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.
