Search Fundamentals

Walk forward slowly. Take small steps no greater

than half normal strides. Make sure each pass of

the loop overlaps the last by at least half the length

of the loop. Do not lift the loop at the end of each

swing. Keep it close to the ground at all times.

To become comfortable with sweeping the loop

takes some practice. Try to loosen up and fi nd a

comfortable grip on the handle. Premature fatigue

may result from gripping the handle too tightly, improperly

adjusted rod or elbow support, and limited

body movement. Hold the handle loosely. Adjust

the rod and elbow support for comfort and keep the

elbow strap loose. Use your arm, shoulder and even

your back a little to allow a smooth even sweep of

the loop.

Now that you're sweeping the loop smoothly over

the ground, you will notice that the detector starts

As the loop is swept over the ground, ignore the

display and concentrate on the sounds the detector

makes.

As the loop is passed over metal that is likely trash,

the sound will be inconsistent. Trash targets typically

produce a shorter, sputter-type sound, that

is often broken or double in nature. Place a steelpop

bottlecap on the ground. Pass the loop over it

several times to become familiar with this sound at

different loop sweep speeds. Note that an aluminum

caps may start reading as quarters due to the elimination

of the iron alloy through deterioration. Once

familiar with the sound typical bottle caps produce,

an operator may pass over such targets and continue

searching without consulting the display information,

saving more time for evaluating possible good

targets.

As the loop passes over metal that is likely a good

target, a more consistent and smooth sound will be

heard. A good target typically produces a longer,

more solid sound. Place a quarter on the ground

and sweep the loop over it several times to become

familiar with the sound of a good target.

Pinpointing the Target

Once the decision has been made to dig, move the

loop off to one side of the target area, squeeze and

hold the TRIGGER on the handle, and "X" the loop

over the spot where you believe the target to be.

Note that the TRIGGER also has a locked forward

position that accomplishes the same thing as

squeezing and holding it.

While the TRIGGER is being held, the loop doesn't

need to be moving to detect the target. The loop

may be moved slowly over the area. The display

will indicate depth in inches and will also show

the strongest reading to aid in pinpointing exactly

where to dig. The shallowest reading on the depth

display, the loudest sound coming from the speaker,

and the two bars lining up with each other, indicate

the center of the target. Don't forget to "X" the

target as pinpointing cannot be accurate unless the

target is swept from at least two different directions.

Once pinpointing is complete, release the TRIGGER,

or return it to the center position.

Pinpointing takes practice. The standard loop provided

with the DFX™ is a high-powered, 12 inch

design. This harmonically tuned loop's strongest

traits are in the detection depth and ground coverage

areas. If pinpointing becomes diffi cult or critical

9. Backlight

Used in dark conditions to light the display,

improving visibility.

Select BACKLIGHT with the ARROW controls

and press ENTER. Use the ARROW controls

to select the desired BACKLIGHT level. The

BACKLIGHT level will be visible on the display.

The current level is shown on the right side of

the display. The graphic control knob shows the

relationship of the current setting to minimum

and maximum levels. Minimum is 0 (no light).

The maximum backlight setting will reduce

battery life by as much as 50% depending on the

type of batteries and how long it is used. Lower

BACKLIGHT settings will have signifi cantly less

drain on battery life.

When the detector is fi rst turned on, it is

normal for the backlight to be on during the

opening display and BATTERY CHECK. If the

BACKLIGHT is off, it will fade when the MAIN

MENU display appears. If the BACKLIGHT is

ON, it will continue until turned off manually or a

different program is selected. BACKLIGHT can

be saved as part of a custom program, for example

a NIGHT HUNT program.

When Backlight is ON and the TRIGGER

is squeezed and released to begin searching,

"BACKLIGHT ON" will appear continually on

the display to warn you of the extra battery duty.

10. Viewing Angle

Adjusts the display for visibility in low or high

temperature conditions.

Select VIEWING ANGLE with the ARROW controls

and press ENTER, use the ARROW controls

to make changes. The current level is shown on

the right side of the display. The graphic control

knob indicates the relationship of the current setting

Basics of Pro Options

intricate adjustments available on this model. The

PRO OPTIONS are divided into fi ve major categories

of menus, structured similar to the Basic

Adjustments. Methods of entry, adjustment, exit,

and reentry remain the same.

To enter the PRO OPTIONS from a search mode,

press MENU and the MAIN MENU will appear.

Use the ARROW controls to select PRO OPTIONS

and press ENTER. The PRO OPTIONS menu will

appear on the display. There are two pages to the

The ARROW controls are then used to select the

desired PRO OPTION category.

The six major categories have options specifi c

to their titles. For example, all the options under

AUDIO have to do with the way the audio circuits

of the instrument behave. Once a category has been

selected and the ENTER control pressed, the ARROW

controls can then be used to scroll through all

the options even beyond that category i.e., beyond

PRO OPTIONS, back to PRESET PROGRAMS,

and BASIC ADJUSTMENTS. The categories will

only reappear if MENU is again pressed, or at specifi

c times during scrolling (to offer short cuts).

From this point forward, we will assume that you

know how to use the MENU control, the Arrow

Controls to make a selection, the ENTER control

to enter or select that option, the Arrow Controls to

make adjustments, and the MENU to exit. Remember,

squeezing and releasing the trigger returns to a

search mode. Arrow Controls can be used to return

from the search mode to the last menu or adjustment

display used.

Pro Options

Be aware that changes you make to a

Program are only in effect as long as

you continue using that Program. If the

detector is turned OFF, the Trigger must

be squeezed and released to recover short

term (volatile) memory upon turning the

detector ON. If you want to keep the

changes you made to a specifi c program

over an extended time period (days or

weeks), or through battery changes, the

entire Program must be saved in a Custom

EEPROM Program position.

1. Ratchet Pinpointing

Pinpointing feature, automatically detunes for easy

target-center locating.

ON - Automatically aids in pinpointing. When the

TRIGGER is squeezed and held for pinpointing,

RATCHET PINPOINTING will shrink the size of

the signal as the loop is passed over the target area

several times. The signal will not fade completely

unless the loop is moved too far away from the

target center.

OFF - When OFF, the signal will remain original

size giving some indication of its size and shape.

Manual shrinking is completed by squeezing and

releasing the TRIGGER several times as the loop

is passed over the target. Manual shrinking can

completely eliminate the target. If the target no

longer responds after manual shrinking, move the

loop away from the target, squeeze and release the

TRIGGER, and again sweep the loop over the area.

If the target is a metal, it should again respond.

until experienced at

pinpointing.

2. S.A.T. Speed

Self-Adjusting Threshold (auto-tune) smooths the

THRESHOLD, OFF (0), or ON (1-10).

Without S.A.T. SPEED (a setting of 0), changes in

the ground (and the passage of time) will tend to

produce changes in the THRESHOLD sound. The

TRIGGER will have to be squeezed and released

repeatedly to maintain the THRESHOLD. This is

particularly noticeable in non-discriminate modes,

although S.A.T. SPEED will also tend to add

stability to discriminate modes. S.A.T. SPEEDs

1 through 10 will automatically correct for such

THRESHOLD changes.

S.A.T. (auto-tune) is a feature that has been used on

metal detectors dating back to the 1970's. It adds

a loop-motion requirement to modes which are

ordinarily non-motion. It is also known to produce

some variations in the responses to hot rocks (rocks

more mineralized than the surrounding ground)

which change with different speed selections.

Only enough S.A.T. SPEED required to maintain

stability is recommended. Typically normal coin

searching requires slower (lower number) speeds,

beach hunting and relic hunting require slightly

faster speeds (higher numbers), and prospecting

requires the fastest settings (highest numbers).

greater stability particularly in non-discriminate modes or

when sensitivity levels are maximized. Typically, faster

S.A.T. SPEEDs (higher numbers) improve performance

in more mineralized ground. Slower S.A.T. SPEEDs

(lower numbers) improve performance in milder ground

conditions. Settings from 0 - 10 are available.

3. Tone I.D.

Assigns each V.D.I. number its own distinct tone or

pitch. Target ranges can easily be identifi ed by their

sound. The higher the V.D.I. number, the higher the

pitch of their sound. Reject targets still break up or

"cutout".

Tone I.D. is used in the discriminate or motion modes.

When ON, each V.D.I. target number has its own

audio frequency or pitch (191 different pitches). The

higher the V.D.I. number, the higher the pitch. Where a

target indicates on the V.D.I. scale can be immediately

recognized. The sound that rejected targets produce

will still be canceled or modifi ed (broken up) by the

discriminate circuit.

The 191 different pitches or tones activated with

TONE I.D. cannot be adjusted as to their pitch. Each

V.D.I. number's sound is predetermined by the factory

and is not adjustable, nor will they shift with TONE

(AUDIO FREQUENCY) adjustments.

and relic searching.

Can be used in combination

4. V.C.O.

Voltage Controlled Oscillator produces a higher pitched

tone the stronger the target becomes.

Voltage Controlled Oscillator is a feature that will only

work in the non-discriminate modes. When it is ON,

the stronger the response the higher the pitch of the

sound. An excellent aid in pinpointing, V.C.O. will only

function when the trigger is squeezed for pinpointing

when activated in a discriminate mode. It will function

full time in the non-discriminate (ALL-METAL)

modes.

D.C. SENSITIVITY settings will dramatically change

the performance of V.C.O. D.C. SENSITIVITY settings

above a level of 35 may peak the audio pitch too

soon to allow V.C.O. to be useful. D.C. SENSITIVITY

settings of 35 or below (lower numbers) are recommended,

particularly in trashy areas where targets are

close to each other.

can work well in combination

with MIXED MODE to

(Audio section)

5. Modulation

Allows motion modes to produce different volume

levels based on target depth.

Modulation is used in the discriminate or motion

modes. When ON, it allows the depth of the target to

dictate the volume of the response. Thus deep targets

can be easily recognized by their lower-volume sound.

If OFF, the discriminate or motion modes will produce

the same volume of response on all detected targets

regardless of depth. The use of MODULATION allows

for the singling out of deep targets in the standard

discriminate mode. It may save time by eliminating

the checking of each target with the depth indication in

the pinpoint mode.

TRAC VIEW offers a way to observe Autotracking.

When ON, "TRACK" will appear momentarily

on the right-hand side of the display just above the

This information is valuable when attempting to

determine an appropriate Trac Speed. It may also

be a valuable aid in determining the relative ground

conditions. Reoccurring "TRACK" would indicate

diffi cult ground. In average ground it is desirable

with different

TRAC SPEEDs to determine

if, and how often,

adjusts Ground Balance.

8. Trac Speed

Trac Speed allows adjustment of the amount of

ground mineral change required to cause Autotracking

to occur. At slower speeds (lower numbers)

it takes a signifi cant change in the ground to

cause tracking to occur. At faster speeds (higher

numbers) it takes very little change in the ground

mineral to cause tracking to occur. The end result,

more tracking occurs at higher numbers than at

lower numbers. Too much tracking can cause errors

in the ground balance setting. Not enough tracking

can result in the ground balance setting never

catching up with changing ground. TRAC VIEW

is used to see how much tracking is occurring.

Generally, a faster (higher number) TRAC SPEED

is needed for more consistent ground conditions.

Slower TRAC SPEEDS (lower numbers) is needed

for more inconsistent ground conditions. "TRACK"

appearing every three to fi ve sweeps of the loop is

the ideal setting when the ground conditions will

allow.

to track the ground slightly more or less than what

would normally be considered perfect, mostly for

experts that prefer a slight offset.

A slightly positive offset can be used to enhance

the responses of small metals (gold nuggets) in

highly-mineralized ground. Positive is indicated by

a slight increase in threshold as the loop approaches

the ground in the all-metal mode. Discrimination

and depth may also be improved.

A negative offset may be used to eliminate particularly

troublesome "hot rocks" in areas that are

otherwise diffi cult to search. Negative offset is indicated

by a loss or slight decrease in the threshold

as the loop approaches the ground in the all-metal

mode.

12. Fine G.E.B.

FINE G.E.B. is used to make smaller adjustments

to the Ground Balance range on either side of the

COARSE setting. The FINE setting combines

with the COARSE setting to determine the actual

ground rejection level. To determine exactly what

level the automatic Air/Ground sequence selected,

it is necessary to check both COARSE and FINE

levels.

Manual Ground Balance will rarely be used for

perfect balancing as the automatic balance is

extremely reliable. It is generally used to offset

Ground Balance for the same reasons AUTO

In COARSE or FINE, lower numbers indicate a

Ground Balance setting toward the negative side

of the V.D.I. scale (iron). Larger numbers indicate

a Ground Balance setting toward the positive side

of the V.D.I. chart (salt). Bad ground conditions

(high mineralization) may be described as either

(positive or high numbers). COARSE and

FINE settings of 0 represent a ground rejection

similar to a V.D.I. number of -95. COARSE and

FINE settings of 255 represent a ground rejection

level similar to a V.D.I. number of +10. This V.D.I.

range from -95 to +10 represents the ground rejection

range of this instrument. If ground balance

(either automatic or manual) occurs near the 255

COARSE setting, signifi cant loss in sensitivity can

be expected to targets which indicate in the V.D.I.

number range of 1 to 10. However, manual ground

balance doesn't exactly work like a discriminator,

where V.D.I. numbers are simply REJECTED. The

actual phase of Ground Balance is out of sequence

with most targets; thus some responses will occur

even if COARSE & FINE G.E.B. are matched

exactly to a particular targets V.D.I. number.

Allows for changing which targets V.D.I. or reference

Program you are using.

Select DISC. EDIT and press ENTER. Now use

the ARROW controls to view the V.D.I. numbers

from negative -95 to positive +95 that appear on

the right side of the display. These are the same

reference numbers that are listed on the top righthand

side of the control box (V.D.I. SCALE or target

chart). For each V.D.I. number, a √ will appear

to the left indicating whether the current program

will ACCEPT or REJECT targets that display that

number.

Use the ENTER control to change any desired

V.D.I. number to ACCEPT or REJECT status.

If you do not save the entire Program into a Custom

Program, the changes you make in EDIT are

only in use as long as you continue to use that

program. The only exception being the temporary

short-term or volatile memory as previously described.

If you make EDIT changes in Coin, and

then switch to COIN & JEWELRY, you lose all

editing you completed in the Coin Program. Each

time a factory Preset Program is ENTERed, all

unsaved settings are overwritten by the factory

recommended settings. Only the Custom Programs

will save your custom settings through Preset Program

Accepting a wider range of V.D.I. numbers will

have an impact on detection depth, particularly for

very deep targets that are diffi cult for the display

so that the positive +95 V.D.I. number is rejected.

The fi rst 30 to 40 negative numbers below zero also

impact detection depth. Most iron indicates further

into the negative numbers. Thus the fi rst 30 to 40

negative numbers can often be ACCEPTed without

digging much iron. ACCEPTing from the positive

numbers down as low as minus 30 to 40 has

the largest impact on the lower end of the positive

numbers. Sensitivity to small jewelry is increased.

However, sensitivity to foil is also increased. On a

beach or in a park that has lots of small foil, ACCEPTing

down to minus 30 to 40 may not be practical.

While ACCEPTing these minus numbers, a

reduced sensitivity setting may help eliminate some

of these small bits of unwanted foil.

ACCEPTing all V.D.I. numbers will produce the

best overall detection depth however, with the

amount of trash in most areas, searching with no

rejection is seldom practical. TONE I.D. is a more

practical choice. The idea of discrimination is to

ACCEPT V.D.I. numbers most likely to be valuables

and to REJECT the V.D.I. numbers most

likely to be trash. Digging ease, and acceptability in

an area will also decide the amount of ACCEPTed

V.D.I. numbers desired. No metal detector can

reject all trash while accepting all valuables. The

deeper you want to detect, the more trash you will

need to accept and dig.

The detector sees metals electronically; thus some

valuable and non-valuable targets may look identical

to the detector. To select ACCEPT and REJECT

V.D.I. numbers is to gamble that the areas you

A factory program which uses the law of averages

Select BLOCK EDIT with the ARROW controls

and press ENTER. The ENTER control can be

used to select either ACCEPT or REJECT. The

ARROW controls can then be used to drag that

BLOCK EDIT not only saves time if large sections

of the V.D.I. target numbers are to be changed, it

also allows peace of mind in the certainty of how

all the V.D.I. numbers are set. In the same amount

of time it takes to view all the V.D.I. number's current

As with EDIT, LEARN changes will only be temporary

If LEARN has been used to develop a discriminate

program, the ACCEPT or REJECT V.D.I. numbers

can be reviewed by using the EDIT feature.

17. Recovery Speed

Speeds target responses, so several targets that are

close together can each respond.

When a metal is detected, it takes a fraction of a

second for the detector to process the signal before

it can respond to another metal target nearby. The

time it takes to process the fi rst metal target signal

so that the second metal target signal can respond

is called RECOVERY SPEED.

There are advantages and disadvantages to fast

(high numbers) and slow (low numbers) RECOVERY

SPEEDS. Faster RECOVERY SPEEDs work

well in high trash areas. However, they will have

some diffi culties with very deep targets as well

as double responses on shallow targets. Slower

RECOVERY SPEEDs do not work very well in

high trash areas. However, they will have better

responses on very deep targets. Slower speeds

also have more defi nitive discrimination sounds.

A custom setting needs to be found that suits the

preferences of the individual and the conditions in

the area. As a general rule, the closer together the

metal targets are in an area, the faster the recovery

speed should be. The more spacing between targets,

the slower the speed should be. Don't use the

fast speed if you don't need to.

against iron occurs.

The advantage of higher BOTTLECAP REJECT

settings is that in high-trash areas more decisive

iron rejection occurs. Trash becomes easier to identify

by the broken sounds they produce.

The disadvantage of a high Bottlecap Rejection

setting is if an iron target is close to a good metal,

detector to cancel both responses. Another disadvantage

is that all targets, iron and non-iron, tend to

start sounding more broken at high levels of BOTTLECAP

REJECT. The operator needs to fi ne tune

BOTTLECAP REJECT according to their preferences

and the conditions being searched.

Some ground conditions make it diffi cult for the instrument

to recognize iron. BOTTLECAP REJECT

allows compensation for these areas.

19. Hot Rock Reject

(Discrimination section)

described or categorized

as either negative/magnetic

(cold rock) or positive/conductive

(hot rock). Typically

a negative or magnetic

“cold rock” will respond in

the search mode, however,

once the trigger is

squeezed for pinpointing it

ceases to respond. A positive

or conductive “hot rock”

will continue to respond

during pinpointing.

If hot rocks are a problem

in the area being searched,

in most cases a HOT

ROCK REJECT setting can

be found that will minimize

their target like responses

compared to real metal

target responses in the +95

category. Settings from

1 - 20 are available.

Hot rocks (rocks higher or different in mineralization

than the surrounding ground) respond as +95

on the V.D.I. scale. Unfortunately in some ground

conditions very deep, small, or unusual real metal

targets may also indicate +95. In the past an operator

would either accept +95 with the DISC EDIT

feature and hear hot rocks as a target response

“beep”, or reject +95 and not hear a target like response

from + 95 target types.

The HOT ROCK REJECT features allows a compromise

between total rejection or total acceptance

of the + 95 V.D.I. indication. Disc Edit Accept or

Reject of +95 will only control the visual displaying

of +95 with the Visual Discrimination feature ON.

To reject or accept +95 with the audio discrimination,

Audio DISC must be on, and the HOT ROCK

REJECT feature adjusted for your preference-regarding

+95.

A HOT ROCK REJECT range of 0 to 20 is provided.

At 0 the same characteristics can be expected

as EDIT ACCEPT +95 has provided with past

Whiteʼs models. At 20 the same characteristics can

be expected as EDIT REJECT +95 provided with

past Whiteʼs models.

At 10 a compromise between accepting +95 and

rejecting +95 is achieved. A hot rock may or may

not produce a target like response depending upon

many factors such as the actual size of the hot rock,

degree of difference between the hot rockʼs mineralization

and the surrounding ground, the current

ground balance setting, and the Sensitivity/Gain

settings.

Hot Rock Reject provides for 19 shades of gray between

totally accepting all hot rocks (0), and totally

rejecting all hot rocks (20).

20. Sweep Speed

(Discrimination section)

or speed hunt would

indisputably be a situation

when an operator would desire

the best performance

with a faster loop sweep

speed. Another area well

suited to faster loop sweep

speeds are large areas that

have few metal items near

each other.

Typically high trash areas,

or older areas that deserve

a slower more methodical

search, are ideal for

slower loop sweep speeds.

Settings from 1 - 20 are

available.

The quickness the loop or search coil is passed from

side to side is critical for modern metal detectors

to perform properly regarding detection depth and

discrimination. Sweep Speed is often a personal

preference feature. Individuals may like or dislike

a particular model based on itʼs required ideal

sweep speed. Additionally an individual may prefer

a quicker sweep speed for a particular area or type

of searching and a slower sweep speed for another

area or type of searching. Most metal detectorʼs

sweep speed is designed into the electrical circuit

and not adjustable.

The SWEEP SPEED of the DFX is adjustable in all

settings except a GROUND FILTER setting of 2.

A GROUND FILTER setting of 2 has a fi xed (not

adjustable) sweep speed.

An adjustment range from 1 to 20 is available. 1 is

the slowest ideal (best performing) loop or search

coil sweep speed, 20 is the quickest ideal (best performance)

sweep speed.

SWEEP SPEED regulates the ideal (best performance)

loop sweep speed by controlling the width

of the target signal the detectors electronic circuit

samples or analyzes. By expanding the sample window

(lower number settings) a slower loop sweep

speed becomes ideal. By narrowing the sample window

(higher number settings) a quicker loop sweep

speed becomes ideal.

RECOVERY SPEED is highly interactive with

SWEEP SPEED and GROUND FILTERING.

Generally faster RECOVERY SPEEDS are better

suited to faster SWEEP SPEEDS. Generally Slower

RECOVERY SPEEDS are better suited to slower

SWEEP SPEEDS. GROUND FILTERING adds

new dimensions to these features. SWEEP SPEED,

RECOVERY SPEED, and GROUND FILTERING

all have a dramatic effect on the way the discrimination

responds to both trash and valued metal

alloys.

21. Ground Filtering

(High Pass Filters or

Differentiators)

(Discrimination section)

often described or categorized

by the amount

of electronic fi ltering used

to distinguish between the

ground, trash, and valued

metal alloys. Typically the

fewer the fi lters, the quicker

the metal detector can

respond between several

metals targets close to

each other. However, detection

depth in mineralized

ground quickly diminishes

with fewer fi lters. Audio

discrimination sounds are

not as pronounced with

reduced fi ltering. The more

the electronic fi lters the

better the detection depth

in mineralized ground and

audio discrimination becomes

more pronounced.

However, more fi lters

equals slower responses

and several targets near

each other become diffi

cult to sort out or respond

separately. Settings from 2

- 6 are available.

GROUND FILTERING is adjustable with the

DFX. The fi rst two primary fi lters are contained

within the hardware (electrical parts). The remaining

fi lters are contained within the computer software

allowing full user adjustment.

The DFX GROUND FILTERING has an adjustment

range from 2 through 6. At a setting of 2

SWEEP SPEED is not adjustable (fi xed).

Selection of 2 fi lters allows for the best performance

in high trash areas of medium to low ground

mineralization. Combined with the RECOVERY

SPEED, and BOTTLECAP REJECTION the DFX

will pull some good targets from previously heavy

hunted high trash areas.

Selection of 3 fi lters will allow for better depth

performance than 2 in slightly higher ground mineralization.

Selection of 4 fi lters allows for the traditional high

end Whiteʼs fi ltering ideal for medium to high mineralized

ground.

Selection of 5 or 6 fi lters allows for new levels of

fi ltering for extreme ground conditions. Although

some models have been described as having 6 fi lters

in the past, two of those six were dedicated to visual

indications alone. The DFX 6 fi lter selection dedicates

all six to ground rejection, discrimination,

and audio detection. For those who search extreme

mineralized ground conditions the DFX with its

multifrequency salt/conductive mineral cancelation

and new levels of ground fi ltration will provide for

performance levels never before available.

22. Visual Disc.

When ON, REJECTed V.D.I. numbers and their

associated ICONS are prevented from appearing

on the display. When OFF, all V.D.I. numbers and

associated ICONS appear.

VISUAL DISC. "ON" eliminates both the V.D.I.

on the display. In other words if Visual Discrimination

is ON, and a specifi c target is rejected (for

example 0-IRON) then 0-IRON will not appear on

the display. If VISUAL DISC. is OFF, all the display

indications will appear regardless of whether

the specifi c V.D.I. number is ACCEPTed or REJECTed.

Visual Discrimination is based on the current discriminate

program.

Visual Discrimination has the advantage of eliminating

is that much of the visual display information

OFF will speed the remaining

24. V.D.I. Sensitivity

Controls how strong a target must respond to produce

a display indication, and controls a third digit

(fraction) of the V.D.I. number.

V.D.I. Sensitivity controls the intensity (strength)

of the target signal needed to activate the display

indications. A low V.D.I. Sensitivity setting would

require a strong target signal to trigger the display

indications. A higher V.D.I. Sensitivity setting

would require very little target signal to trigger the

display indications.

To provide greater specifi c target resolution, levels

of 86 and above will provide a third V.D.I. digit

(.0) to better evaluate targets. During EDIT only

the fi rst two digits can be programmed ACCEPT or

REJECT.

As with all sensitivity levels, if set too high for

the area, the detector will become unstable and the

display indications unreliable.

Low ground mineralization is typically a good

indication that high V.D.I. sensitivity settings are

appropriate. Heavy mineralization or electrical

interference are conditions where a lower V.D.I.

Sensitivity setting is appropriate.

This feature is designed to allow adjustment of the

display stability. However, because the instrument's

display and audio tone are closely associated in

many of the audio modes, the V.D.I. Sensitivity

may increase or decrease overall audio sensitivity.

(Display section)

level (smaller

numbers) offer fewer and

more reliable display indications.

However, some

deep targets may or may

not respond with a display

indication. Higher V.D.I.

SENSITIVITY levels (higher

numbers) produce more

display indications, but less

reliability. Levels of 86 and

above produce a third V.D.I.

digit (.0), providing greater

resolution. Settings from 0

- 99 are available.

25. D.C. Phase

Measurement of the ground mineralization, or

measuring the phase (V.D.I. reference number) of a

specifi c metal target during pinpointing.

When D.C. PHASE is ON, and the TRIGGER

squeezed and released, normal searching begins.

When a target is located, or when the operator

wants to measure a target or the ground, the TRIGGER

is squeezed and held as if to pinpoint. When

the loop is held stationary over the target or ground,

the D.C. PHASE is shown on the upper-right side of

the display. The depth reading can be used to help

center the loop over a target for more accurate indications.

The audio tone will also assist in centering

the loop over the target.

Metal targets in the ground will produce a measurement

which represents the target indication ± the

ground measurement. To measure the target alone,

move the loop off to one side (being sure to hold

the loop directly on top of the ground mineral),

and release and re-squeeze the trigger. Then move

the loop back over the target. This should allow a

proper D.C. PHASE reading for the target alone.

The relationship between D.C. PHASE, Ground

Balance, V.D.I. number and Discrimination is complex.

Results are not always repeatable in varied

ground conditions. Ground and target responses can

distort the detection fi eld of the loop in a number

of ways, by bending, refl ecting, absorbing and thus

altering the phase and amplitude the detector measures.

This in turn produces inconsistencies in the

relationships of these features.

When considering specifi c numbers it is important

to know D.C. phase is provided by the 15 kHz

channel without normalization. The V.D.I. scale

is distorted/expanded in the lower end of the scale

(foil/nickel) and compressed in te higher end of the

scale (copper/silver).

Adjustments and Pro Options

performance. By measuring

the ground and taking

notes, such conditions may

also be recognized in other

areas and dealt with by using

similar settings.

The D.C. Phase of the ground has a relationship

to the proper Ground Balance setting. This is of

particular interest to those who use the optional

COARSE or FINE G.E.B. (Manual Ground Balance).

Manual Ground Balance has a range that

covers V.D.I. numbers from -95 - +10. A Manual

Ground Balance Coarse setting of 0 equals a

D.C. PHASE of negative -95. A Coarse setting of

255 equals a D.C. Phase of +10. As mentioned

under COARSE and FINE G.E.B., Ground Balance

is not the same as EDITing these V.D.I.

numbers for REJECT. However, if your ground

measures -90, ACCEPTing

V.D.I. -90 will produce operational problems as

the detector will see the ground as a target. With

the same logic, if a target measures -90, and the

ground measures -90, and the detector is Ground

Balanced to this -90 ground, such a target will be

virtually invisible to the detector. These conditions

would be extremely rare however; the point is

there must be a difference between the target and

the ground for the target to be detected.

(Multi Frequency Method section)

30. 2 Frequency (Best Data)

Transmits and processes data continuously at both

3 kHz and 15 kHz frequencies (salt eliminated).

Automatically chooses to use only the data from the

most reliable frequency (based on both magnitude

and phase) for each specifi c target.

Gold, nickel, and other lower conductive metals respond

more reliably at higher frequencies. Copper,

silver, and other higher conducting alloys respond

more reliably at lower frequencies. 2 Frequency

(Best Data) uses the multi frequencymode to cancel

ground and salt and then selects the most ideal

frequency for that particular target alloy on a target

by target basis.

31. 2 Frequency (Correlate)

Transmits and processes data continuously at both

3 kHz and 15 kHz (salt eliminated). Compares

data at 3 kHz and 15 kHz. Target signals that do

not provide reasonably predictable information at

both 3 kHz and 15 kHz are automatically rejected.

Iron typically doesnʼt compare predictably between

frequencies and thus improved iron rejection can be

expected with the use of Correlate.

Differences in the target signal at 3 kHz and 15 kHz

are predictable regarding valued metal alloys such

as gold, copper silver, etc.. If the two signals do

not match within a reasonable range of predictability,

most likely the target is not a valued metal and

therefore is rejected.

Only one of the four available multifrequency

methods, BEST DATA, CORRELATE, 1 kHz,

and 15 kHz, can be "ON" at any one given

time. For example if BEST DATA is "ON",

the remaining three multifrequency options

are automatically "OFF". To turn BEST DATA

"OFF", requires the selection of one of the three

remaining methods. In other words, an operator

never turns "OFF" a multifrequency method,

they simply select the desired method and turn

it "ON", all other methods are automatically

turned "OFF."

The MULTI FREQUENCY selection in use

appears continuously on the bottom of the LCD

display during searching. The ideal multi frequency

or single frequency setting will depend

on many different factors such as the amount,

degree, and type, of ground mineralization, the

types of metal alloys most desired, as well as

personal preferences. No one setting will be ideal

for all situations. A user should fi rst trust the

factory preset settings for the general types of

searching and then experiment to fi nd the most

ideal settings for that particular area and type

of search. Generally multi frequency settings

are better suited to areas that have both magnetic

(iron) and conductive (salt) components.

Inland areas may vary in this regard with the

soils moisture content. For example dry soil may

present mostly iron type characteristics possibly

making one of the single frequency modes a

better choice. The same area when the soil is wet

may exhibit conditions similar to a combination

of both iron and salt due to nonferrous metallic

type mineralizationʼs greater electrical activity

when wet. For example soils containing silver,

copper, or nickel oxides/nitrates react differently

in conditions from wet to dry. These soil traits

can occur naturally and are typical of areas with

mineral springs or volcanic origins. However,

be particularly aware of this wet/dry phenomena

in farming areas where the soil mineralization is

likely altered for agricultural purposes.

V.D.I. Normalization - Used in the 1 frequency

operating modes to correct the skewing of the traditional

(6.59 kHz) V.D.I. number display calibration.

2 Frequency modes require Normalization and thus

it is automatically ON in both the 2 Frequency (Best

Data) and 2 Frequency (CORRELATE) operating

modes. It is not an option in 2 Frequency modes.

When operating in the 1 Frequency (3 kHz) mode

Normalization ON recalculates the V.D.I. display

information to represent traditional V.D.I. display

calibration at Whiteʼs traditional frequency 6.59

kHz.

When OFF in the 1 Frequency (3 kHz) mode the

V.D.I. scale is distorted/expanded in the higher end

of the scale (copper/silver) and compressed in the

lower end of the scale (foil/nickel). This distortion

can be used to provide higher display or discrimination

resolution in this copper/silver coin area of the

scale. DISC EDIT will have to be confi gured to take

advantage of this expanded resolution.

When operating in the 1 Frequency (15 kHz) mode

Normalization ON recalculates the V.D.I. display

information to represent traditional V.D.I. display

calibration at Whiteʼs traditional frequency 6.59

kHz.

When OFF in the 1 Frequency (15 kHz) mode the

V.D.I. scale is distorted/expanded in the lower end

of the scale (foil/nickel) and compressed in the

higher end of the scale (copper/silver). This distortion

can be used to provide higher display or discrimination

resolution in this foil/nickel area of the

scale. DISC EDIT will have to be confi gured to take

advantage of this expanded resolution. The advan-

1 Frequency (3 kHz) - Operates at 3 kHz exclusively.

Provides for superior high iron mineral rejection

and depth when salt is not present. Also provides

for better depth on higher conducting metals such as

copper and silver alloys.

1 Frequency (3 kHz) provides an alternate search

mode when iron (without the presence of salt) is

extreme and the primary target is higher conducting

metals such as copper or silver. Some of Whiteʼs

early 1970 models operated at 3 kHz and are still

revered for there performance in high iron black

sands.

1 Frequency (15 kHz) - Operates at l5 kHz exclusively.

Provides for superior performance in medium

to low mineralization (without the presence of

salt) and/or when lower conducting gold and nickel

range targets are the primary targets.

1 Frequency (15 kHz) provides an alternative

search mode when the ground minerals are not

severe (without the presence of salt) and/or when

the low (foil/nickel) end of the scale. In the 15 kHz mode the opposite occurs.

The high end compresses and the low end expands.

Factory Pre-Loaded Custom

EEPROM Programs

Whiteʼs has pre-loaded each of the four custom

EEPROM Program positions for you. These programs

can be erased simply by developing your

own program, starting with any of the nine available

programs, and using the SAVE or NAME feature

(pages 16-17).

The fi rst fi ve Factory Preset Programs are burnt

into permanent memory EPROM (Electronic,

Program-mable, Read, Only, Memory). Although

you can make changes to these programs while in

use, and you can modify and copy/save them to the

EEPROM positions for future use through battery

changes, the Factory Preset Programs will always

revert to their original factory settings. Only the

programs saved in one of the four available EEPROM

positions will save through battery changes.

Short term memory recall (ON and squeeze and

release the trigger) will maintain changes to a factory

program if a good battery remains in the unit.

To assure you retain special settings it is advised to

Save or Name them in one of the EEPROM positions.

Once you modify and Save/Name a factory

program to one of the EEPROM positions it is no

longer a Factory Preset Program and thus will save

for future use.

EEPROM stands for a special type of electronic

memory chip (Electrical, Erasable, Programmable,

Read, Only, Memory). This memory chip allows the

user to store up to four of their own programs for

future use through battery changes and storage.

To use a custom EEPROM Program Simply;

1. Turn the detector ON and wait for the

Main Menu.

2. Press ENTER to enter the Preset programs.

3. Use ARROW DOWN to scroll down the

Preset Program pages/screens until you see

thecursor beside the EEPROM program

you desire.

4. Press ENTER.

5. Press ENTER again to LOAD the program.

6. Air/Ground Balance and your ready to search

using the program stored in that position.

To store the current settings you are using do the

same thing only instead of LOAD, select SAVE or

NAME. LOAD it when you want to use those settings

again. Save or Name if you want to save the

DFXʼs current settings.

The idea is that once you have determined your

preferences for the particular features and settings,

you can store that entire program in one of the EEPROM

positions and have it ready for use whenever

you desire, without having to go through all the

options. Save your settings for future turn on and go

use.

Pre-Loaded EEPROM Programs

A good general purpose program where the

majority of the trash is iron and small/

medium foil and the majority of the ex

pected targets are coins.

Popular performance modifi cations include:

Turning ON V.C.O..

Ground Filtering adjustment 2 for lower

minerals 3 medium minerals.

AutoTrac Offset +2.

Remember...if consistently digging a

particular trash target, simply make note

of the typical V.D.I. reference numbers,

go to Disc Edit and change those specifi c

V.D.I. numbers for rejection. Re-save

any changes if future use is desired.

Provides a primarily coin program targeted more

toward trashy public areas. Rejects common

aluminum at the sacrifi cing of some jewelry.

Jewelry 18 K and above in the medium size

category is not likely to respond. However, areas

of common abundant aluminum trash can be

searched with good coin results as well as 14K

jewelry in the medium to small category. The

only way to get all the jewelry is to dig all the

aluminum, lead, and brass, which can be tedious

to the point of frustration in trashy areas.

Popular Performance modifi cations include:

Tone I.D. ON

V.C.O. ON

Ground Filtering 2 for lower mineral areas,

4 for more mineralized areas.

Auto Track Offset +2

Visual Disc ON

D.C. Phase ON

Re-save any changes if future use

is desired.

AC Sensitivity 65

1 Frequency (3 kHz)

Re-save any changes if future use

is desired.

Primarily a showroom or bench program for

testing or demonstrating, likely the fi rst

EEPROM slot an individual would choose to

save their own program in place of.

A high performance general purpose program not

for the meek at heart. Advanced features TONE

I.D., V.C.O., wide open DISC EDIT acceptance

of all nonferrous (valued alloy) targets, and high

Sensitivity/Gain, make this program really sing

for those who can handle the various audio

pitches and depth of information. If you like

silent search, this isnʼt the program for you

Sensitivities and Gains may need to be reduced

in areas of heavy electrical interference.

Popular Performance modifi cations include;

Mixed Mode ON

Tone I.D. OFF

Autotrac Offset +5

Ground Filtering 2 for lower

mineralization, 4 for higher

mineralization.
