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 different metal objects, e.g. various coins, gold and silver jewellery,
arusted nail, pull-tab, brass button and aluminium foil.
Take the detector outside, away from known electromagnetic fields or metal objects.
Lay objects in a line, sufficiently spaced apart to allow the coil to pass between the objects.
This test exercise can be used when adjusting the detector’s settings (Sensitivity, pg. 44, Volume, pg. 46, Noise Cancel*, pg. 48, Ground Balance*, pg. 50)
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 (pg. 44). Once stable, the detector will only sound and display numbers when the coil
