a simple deteCting exerCise

Pass the coil across the objects, one at a

time, and observe the LCD and the detector’s

sounds as it detects each object.

Note: If you are getting signals from a clear

patch of ground, there may be unknown buried

metal objects.

Before attempting to pinpoint or recover real

targets it is important to understand how

to interpret the audio and visual responses

correctly.

If the detector is making popping and

crackling sounds and displaying numbers

when the coil is not over one of the metal

objects, try reducing the detector’s Sensitivity

(p. 46). Once stable, the detector will only

sound and display numbers when the coil is

passed over a target.

A good way to become familiar with detecting

is to test the detector against a range of metal

objects. This exercise is a simple lesson on how

the detector interprets metal objects.

Gather a collection of dierent metal objects,

e.g. various coins, gold and silver jewellery,

a rusted nail, pull-tab, brass button and

aluminium foil.

Take the detector outside, away from known

electromagnetic elds or metal objects.

Lay objects in a line, suciently spaced apart

to allow the coil to pass between the objects.

This test exercise can be used when

adjusting the detector’s settings

(Sensitivity, p. 46; Noise Cancel, p. 48;

Volume, p. 52; Ground Balance, p. 56)

Don’t worry if the detector isn’t producing

a sound over the nail, this is because the

detector begins in the default Pattern 1, a

setting which rejects signals from common

junk targets.

The X-Terra coil is waterproof.
