Adjust the elbow cup strap so that it is loose

enough for you to slide your arm in and out with-

It should be noted at this point that the detector

may not work as expected indoors due to the high

degree of metals used in modern construction. It

is best to tune and practice out-of-doors to ensure

buried targets will not produce the normal depth

naturally lost and settled in the ground. Due to the

matrix, and the sophistication of the ground rejec-

tion circuitry, it may take a number of years for

freshly-buried targets to respond at true depths and

discrimination accuracy. The best way to determine

true detection depth is in real search conditions.

Your DFX is designed to automatically turn

itself OFF if the trigger on the grip (or another

control) “is not used” for a period of 10-15

minutes. This protects the battery from damage

in case of an accidental turn on during travel or

pinpointing/depth reading (keeping the detector

operating) is encountered during each 10 minutes

of search. If searching an unusually area, free

of concentrations of metal, the DFX will make

to resume searching. So long as a good battery

remains, the DFX returns to the exact settings prior

to turning itself off.

Assembly Instructions

top of the curved "S" rod, about ﬁ ve revolutions.

Use the black cable retainers, one near the loop,

and one near the top of the curved "S" rod, to hold

the loop cable in place.

Unlock control box rod camlock and insert

curved "S" rod so that stainless steel spring clip

buttons line up and lock into the rod on top of the

control box. The "S" rod is designed to curve up

toward the display. However, those who prefer to

assemble the "S" rod to curve down toward the

ground. Turn camlock to secure. Plug loop con-

nector into control box, screw lock ring to secure.

Chapter 1 DFX™ Assembly

Grip the instrument by the handle, with your arm in the elbow cup with strap secure, and sweep the loop/search coil over the ﬂ oor. If the instrument ﬁ t feels uncomfortable, adjust the elbow cup by removing and repositioning the bolt/thumbnut and installing in one of the optional positions. If necessary, readjust clevis/lower rod length with the spring clip buttons so that the search coil can be held near the ﬂ oor without requiring stooping over.

Chapter 2 DFX™ Batteries

Standard Battery Holder

The standard battery holder (blue decal) holds

eight “AA” cell batteries. Alkalines are recom-

mended for use with this battery holder.

Non-alkaline batteries can be used in this holder.

When non-alkalines or rechargeable “AA”

cells are used, detecting time (before replacement/

recharge) may be reduced.

"LOW BAT" will automatically appear on the

display when the batteries become too low to prop-

erly operate the detector.

The battery compartment opens by gently pull-

ing down on the front of each of the two latches

catch and hinging open the door.

The non-rechargeable battery holder can use many

different types of batteries, including rechargeable.

This holder is designed for standard size penlight

Battery lengths shorter than this will likely cause

problems with this power supply.

When the instrument is turned on the battery volt-

The battery will lose its charge during stor-

age. If stored inserted in your instrument, this loss

will be more noteworthy. It is recommended that

the battery be removed from the instrument dur-

ing periods of storage. It is not advisable to store

rechargeable batteries for long periods of time

without use. If however, storage is necessary, store

without a charge (discharged).

Do not discharge the battery in devices other

than your metal detector. Unnecessary discharging

and/or an absolute discharge will reduce battery

life and may damage the battery. Unlike older re-

chargeable battery designs, the rechargeable battery

provided with your detector can be recharged at any

time.

Regardless of whether or not it already has a

partial charge, memory will not occur.

White's has provided the leading edge of re-

chargeable battery technology with your instru-

ment. Disregard all advice which conﬂ icts with the

above recommendations. Care for batteries pro-

vided by other manufacturers, or with other White's

models, may vary.

Charging

There is no harm charg-

ing overnight using the

OVERNIGHT charge

battery's current condition.

However, before charging

with the QUICK charge

condition by inserting bat-

tery into the instrument and

turning the instrument ON.

If the instrument will not

turn ON, or if voltage tests

eight volts or below, charge

ﬁ ve hours with the QUICK

charge. If the battery voltage tests any other volt-

proper QUICK charge time.

To charge, insert the charger plug into the battery

pack jack, located near the plastic tab and

metal contact points.

Plug the charger into a standard wall outlet. (110

volts for USA models).

Again, the QUICK charge setting uses the above

chart for a speciﬁ c charge time. OVERNIGHT is

designed to charge the battery in as little as fourteen

hours. However, no harm will come to the system

leaving it charging for several days.

It is normal for the battery and charger to get

warm during use. However, if either the battery or

the charger gets too hot to hold or deforms due to

the heat, discontinue use and return for testing.

Chapter 2 DFX™ Batteries

Volatile memory

temporarily holds any program

changes or settings not yet saved in a Custom Pro-

gram.

Short-term

or volatile memory is retained so

long as a good battery remains in the detector. To

recover volatile memory immediately squeeze and

release the TRIGGER once the detector is turned

ON. If the battery is removed all volatile memory

is lost.

Long-term

memory (programs saved in

Custom Programs) is automatically saved for up to

ten years regardless of whether a battery is in the

detector or not.

When using fresh batteries, the voltage will initially

check somewhere in the 10 to 14 volt area. Unlike

will quickly drop to between 9 and 10 volts and

plateau there for most of its life. Once the recharge-

able battery voltage drops below this plateau, it will

quickly drop below a usable voltage level (eight

volts) and thus require a recharge.

Low Battery

will

automatically appear on the display when the bat-

tery reaches eight volts.

Like a personal computer, there are times (such as

low battery conditions) when the microprocessor of

a metal detector becomes out of sequence with the

rest of the circuitry. This is often noted by peculiari-

ties in the nondiscrimination or pinpointing (TRIG-

GER squeezed) modes. Symptoms may be blaring

or silent non-discriminate or pinpoint modes, depth

indication inaccuracies or general abnormal opera-

tion. To correct such difﬁ culties "re-boot" by:

2. Turn ON wait for MAIN MENU to appear.

3. Open battery door and remove battery while

detector is still ON.

4. Wait one minute, reinstall battery, turn

detector ON, and check for proper function.

Use of maximum backlight may reduce battery life

by up to 50%, depending on battery type.

Rechargeable batteries gradually deteriorate. As

they age they do not provide the life-per-charge

they did when new. This is expected, and not

grounds for replacement under warranty. Addition-

charging with the QUICK option,

use, or a defect due to a problem with a White's

warranted DFX

charger, is covered.

Chapter 3 DFX™ Quick Start

Search Fundamentals

The loop/search coil must be in motion (sweep-

ing from side-to-side) for this instrument to

respond to metal.

Practice a smooth sweep of

the loop from side-to-side keeping the loop close

to the ground throughout the swing.

Each pass of

the loop should take approximately two seconds

from right to left, two seconds to return from left

to right.

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

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, im-

properly 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

making sounds

Not all sounds are good

targets; some trash targets also make the detec-

tor

beep.

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 typi-

cally produce a shorter, sputter-type sound, that

is often broken or double in nature. Place a steel-

pop bottlecap on the ground. Pass the loop over it

different loop sweep speeds. Note that an aluminum

twist-off bottlecap

cannot

be used as it is a different

type of target. Also note that very old rusty bottle

caps may start reading as quarters due to the elimi-

nation of the iron alloy through deterioration. Once

familiar with the sound typical bottle caps produce,

tion, 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

familiar with the sound of a good target.

Why Air/Ground Balance?

TER. The DFX

Edit feature allowing you to reject or accept targets

based on their V.D.I. reference number. There are

and "-" numbers for ferrous (iron) targets. Rejected

V.D.I. numbers may not appear if the VISUAL

DISCRIMINATION feature is ON. Reasonably

consistent V.D.I. reference numbers (± ﬁ ve digits),

2. Possible Target Identities ("Probable or most

likely target")

To the right of the V.D.I. number, possible target

identities will be represented graphically. These

graphics are called ICONS. A fairly consistent indi-

cation of a desirable target is another vote to dig

the target. One or two possible target icons may

appear. There is signiﬁ cance to which icon appears

ﬁ rst. The ﬁ rst target to appear is always the most

likely, the second is another possibility, slightly less

likely than the ﬁ rst.

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 for-

ward position that accomplishes the same thing as

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

need to be moving to detect the target. The loop

target as pinpointing cannot be accurate unless the

target is swept from at least two different directions.

Once pinpointing is complete, release the TRIG-

GER, or return it to the center position.

Pinpointing takes practice. The standard loop pro-

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

design. This harmonically tuned loop's strongest

traits are in the detection depth and ground cover-

Permission

- Prior to searching and digging you

must have permission to search private property,

from the owner or caretaker.

Laws

- Know the laws that apply to the area you

are going to search. Laws vary a great deal with the

City, County, State, and Country, regarding the use

of metal detectors. Be respectful of private prop-

erty, public property, and the laws which govern the

use of metal detectors.

Tools

- Care must be taken to dig in a way that is

friendly to the landscape. Tools and methods vary a

great deal with the area, season, and types of target

you are recovering. Check with your dealer for

recommended tools and methods for your area.

Trash

- When searching, remove all trash you come

across. This not only makes your future searches of

the area more productive; it promotes the hobby of

metal detecting.

Get Involved -

Your dealer knows of metal detect-

ing clubs and organizations which promote and

protect the hobby. A club is a great way to not only

learn good detecting habits, but to gain permission

to search areas as a group as well as have organized

competition hunts.

Trac Speed allows adjustment of the amount of

ground mineral change required to cause Auto-

tracking to occur. At slower speeds (lower num-

bers) 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 track-

ing 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

TRAC OFFSET allows the AUTOTRAC

A slightly positive offset can be used to enhance

the responses of small metals (gold nuggets) in

highly-mineralized ground. Positive is indicated by

es the ground in the all-metal mode. Discrimination

A negative offset may be used to eliminate par-

types of targets it cannot readily identify. There-

fore, if positive +95 is ACCEPTed, questionable

targets may be dug that indicate this number and

can produce some interesting recoveries.

A good

tip regarding positive +95: If a target indicates

95, and the depth display indicates it as being fairly

deep;

dig it

being fairly shallow, it is more likely to be trash or

a hot rock. HOT ROCK REJECT in the Pro Options

has 20 levels available for the acceptance or rejec-

tion of +95. An operator can adjust HOT ROCK

REJECTION to suit personal preference and area

demands. (See page 42.)

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 posi-

tive 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, AC-

CEPTing down to minus 30 to 40 may not be practi-

cal. 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 valu-

ables 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 identi-

cal to the detector. To select ACCEPT and REJECT

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

will be good targets, and the

REJECT

will be trash targets.

A factory program which uses the law of averages

usually produces more good targets than trash. The

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 ide-

al for all situations. A user should ﬁ rst trust the

of search. Generally multi frequency settings

are better suited to areas that have both mag-

netic (iron) and conductive (salt) components.

Inland areas may vary in this regard with the

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,

Whiteʼs has pre-loaded each of the four custom

EEPROM Program positions for you. These pro-

grams can be erased simply by developing your

own program, starting with any of the nine available

programs, and using the SAVE or NAME feature

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 EE-

PROM positions will save through battery changes.

release the trigger) will maintain changes to a fac-

tory program if a good battery remains in the unit.

To assure you retain special settings it is advised to

tions. 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

NAME. LOAD it when you want to use those set-

tings 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 EE-

PROM 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.

EEPROM DP-SILVER (Deep Silver)

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.

EEPROM HI-TRASH

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.

EEPROM DEMO

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.

EEPROM HI-PRO

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.
