X-Terra Controls

The machine couldn’t be simpler!

Furthermore, there are some really

clever features built into the operation

of the machine that you are bound to

notice - but more on that later. For now

let’s examine the control panel.

Power. This turns the unit on and

off. It also erases patterns and enables

factory preset. Power for the X-Terra is

supplied by four 1.5 volt AA cells that

are held inside the control box via a

hinged door. These should power X-

Terra for 25 hours (alkaline cells).

Menu Select. Accesses and scrolls

through detecting settings.

Pinpoint/Detect. This has two

functions: (a) assists in locating the

exact position of targets, (b) exit menu

settings and returns to “Detect”.

Plus and Minus. Adjusts settings

and scrolls to the left (-) or right (+)

through the discrimination segments.

Patterns. Scrolls through the differ-

ent discrimination patterns.

Accept/Reject. Turns on/off indi-

vidual discrimination segments.

All-Metal. Toggles between the

selected discrimination pattern and the

all metal pattern.

Ground Balance. Activates the

manual adjustment to compensate for

different types of soil. This function

couldn’t be easier and quicker! Just

press, bob the coil up and down a few

centimetres above the ground and -

using either the plus and minus button

- find where the two tones merge into

one and dip in volume; press Detect

and you are ground balanced. Bear in

mind that this might not be possible

over wet salt beach conditions, but it is

possible to use the X-terra on salt wet

sand by adjusting sensitivity and dis-

crimination accordingly. Similarly, if

there is a difficulty ground balancing on

any soil, reduce sensitivity and try

again.

Keypad Layout

This is very nice indeed with the

most used buttons falling to easy reach

of the thumb or forefinger. An espe-

cially nice touch is that the Pin

Point/Detect and All-Metal buttons are

strategically located so you can jump

from one to the other with consider-

able ease. Also, if “iffy” signals are

heard that might be deep iron or some-

thing breaking through a created

discrimination pattern simply press

All-Metal and look at the screen. If a

low tone accompanied by a -9, -6, or -3

number appears the target is probably

ferrous. Re-press All-Metal and it goes

straight back to your created pattern –

no need to touch the Patterns button.

This is one of the clever features

referred to earlier.

Probably the most important button

is the Menu Select. This takes you

through the adjustable functions in the

detector:-

1. Volume from 1-20

2. Sensitivity from 1-20

3. Noise Cancel of which there are 3

channels: 0 which is Pre Set, +1 and -1.

Meter Layout

The meter is divided into eight dif-

ferent areas of information for your

attention.

1. The two discrimination patterns

are icons shown as 1 & 2. (Note there

is also an icon for All-Metal shown on-

screen as AM).

2. Ferrous area -3, -6, -9.

3. Non-Ferrous + 3 to + 45

4. Depth indication – five arrows in

a V shape scrolling down (reasonably

accurate on coins to about 20cm).

Note on Discrimination: Where

some discrimination has been selected

a small black block at the bottom of the

meter will be illuminated, typically this

will be ferrous based with -3, -6 and -9

rejected. You can decide what your dis-

crimination pattern will be for a site

you would like to search. For example,

if beach detecting, you decided pull-

tabs and whole cans were a problem

you could select to reject block number

+ 12 and + 36. Another clever feature

of the X-Terra is that the Overload func-

tion can help in identifying shallow

cans. However, on a site that could

reward with hammered coins it would

be best to accept numbers + 3 to + 18

(and possibly lower and higher depend-

ing on how worn and/or clipped coins

might be).

5. On the meter there is something

I have never seen before on any detec-

tor and that is a visual icon showing

when the headphones are connected.

Seeing this at first I found it rather odd,

until I discovered its real function and

again it is where the clever side of

Minelab design shines through. X-Terra

can remember two different volume

levels one being with headphones and

the other without and it will revert to

either one automatically when you

insert or remove the headphones -

ingenious! The headphone socket is

quarter inch and is recessed inside the

control box, which has a rubber dust-

proof cover which should be kept

closed when not in use

6. Battery level indicator icon –

shows two black blocks for a new set.

There is another clever side to the vol-

ume output of X-Terra, and that is if

you operate without headphones the

volume level diminishes as the battery

cells become depleted to preserve

usable power so you can detect for

longer than another conventional

machine.

7. ID Number Blocks – these are

very large digital numbers, which cor-

respond to the conductivity of detected

targets. The numbers will be positive

when targets are non-ferrous and with

a minus slash for ferrous items if oper-

ating in All-Metal. The four tones will

also range from low for ferrous to high

for very conductive.

8. Pin Point function – has an outer

solid circle in which another complete

circle will be produced concentrically

when the coil is right over the centre of

the target. The further the coil is from

the target the inner line will drop down

and come fully up the closer you get to

the buried target. Visually this is a treat

and is a delight to use as it provides

some of the best pinpointing I have

come across. It also features an audible

rising crescendo tone, which peaks

when you hover over the target.

In your Factory Discrimination Pat-

tern - or one that you will build and use

yourself - there are “Discrimination

Segments” or blocks assigned to all the
