One of the more obvious changes is

the logo on the side of the box, which

now reads “White’s DFX Spectrum E-

Series”. Also printed on the control box

is the start-up procedure and a target

identification display scale. On the

underside is a “Hot Key” shortcut chart

that enables easy access from the

search mode to the most needed

adjustments. Among the less obvious

changes are: dual frequency operation,

four new user-designed programmes,

adjustable sweep speed, and a digital

signal filtration system.

Set Up

The pre-set programmes in the DFX

allow the user to push a couple of pads

to begin searching while the detector

automatically controls the adjustments

for you. Beginners will find this facility

the best option until they become

familiar with the many adjustments

that the more accomplished detectorist

will want to access.

Looking at the display panel you

will see five push button control pads.

Reading from left to right they are

marked: Menu, Arrow (down), Enter,

Arrow (up), On/Off. The detector is

turned on by pressing the On/Off pad,

at which point an automatic battery

test is carried out. The screen will

momentarily show the battery voltage

followed by the main menu. To

recheck the voltage, squeeze and hold

the trigger while pressing the down

arrow. When the battery strength

becomes too low for proper function

of the detector, the words “Low Bat”

will automatically appear on the

display.

The main menu offers a number of

choices commencing with “Preset Pro-

grammes”. To access this setting simply

press Enter after which a choice of five

preset programmes appear on screen

with an arrow pointing to the first

“Coins”. By pressing Enter (a bleep sig-

nal will be heard each time it is

pressed) and following the instructions

on the screen to raise the search coil to

waist level, press Enter again then

lower coil to ground level. The detector

will now be correctly ground balanced

and ready for operation in the Coins

programme. While the coil is held at

waist level the DFX’s circuitry is mea-

suring air temperature and other vari-

ables that effect electronic circuits.

When lowered to ground level and the

Enter pad is pressed again, the DFX is

cancelling out the ground mineralisa-

tion effect (or ‘Ground Balancing’ the

detector). In this and the other four

preset programmes no further adjust-

ments are needed. Nevertheless, any

number of control adjustments are

available to meet almost any need or

style of detecting.

The last screen to appear will be the

search screen, at which point you will

also hear the threshold hum. After

sweeping the coil across the ground lis-

ten for a repeatable solid signal and

look at the display. The icon will show

what is likely to be below the search

head and the VDI (Visual Display Iden-

tification) number can be checked

against the chart on the control box.

The SignaGraph section of the screen

provides even greater information.

Because this is a motion type detector

the search coil must be kept moving to

respond to a target. (See Mixed Mode).

Other Menu Options

We have already covered the first

option on the VDU, Preset Pro-

grammes. The other options are: Basic

Adjustments, Pro Options, and Custom

or EEPROM programmes. Within these

headings there are a number of set-

tings, such as RACHET PINPOINT,

COARSE GEB, PREAMP GAIN and

many others that may not be familiar to

users of different makes of detectors.

With more than a little help from the

manual, I will try to explain in detail

what these terms mean.

EEPROM stands for Electrical

Erasable Programmable Read-Only

Memory, which is a memory chip that

allows the storage of up to four custom

programs despite battery changes and

years of storage. These four “memory

slots”, along with the five Preset Pro-

grams, add up to a total of nine pro-

grams that should fit just about every-

one’s needs. The four EEPROM

programmes can be erased and replaced

with your own custom programmes.

Setting them is a simple operation and

I will cover this in the field test part of

this report.

The first five Preset Programs are in

permanent memory, with a similar

looking name of EPROM (notice that

one E is missing for Erasable). Changes

made in these programs will return to

factory settings when you change from

one program to another or change bat-

teries. However, if you have made

changes and forget to save them in a

custom program before turning off the

machine, all is not lost. With a good

battery still intact, squeeze and release

the trigger immediately upon turning

the detector back on, and the circuitry

will revert to the last settings used.

Otherwise, settings will revert to fac-

tory preset.

Preset Programs

The following is an explanation of

each Preset Program.

Coins - All controls are set to han-

dle rubbish contaminated areas such as

parks, responding to most coins and

larger jewellery. Discrimination is high

in order to eliminate signals from items

like nails, foil, ring-pulls, and “hot

rocks”. If possible, though, try to start

with a program of low discrimination,

as good items can be missed along with

the bad. This is true for all metal detec-

tors due to various reasons such as the

conductive properties of different met-

als. This program will save you a lot of

digging in badly contaminated areas.
