Simple Detecting Exercise
Before attempting to recover real targets, it is important to understand how to
interpret the audio and visual signals of the detector.
1. Gather a collection of dierent metal objects, e.g. various coins, gold and silver
jewelry, a nail, pull-tab, brass button and aluminum foil.
2. Take the detector outdoors, away from known sources of electromagnetic
interferences (EMI) and metal objects.
3. Lay objects in a line, suciently spaced apart to allow the coil to pass between
them, as shown in Figure 44.

NOTE
As the coil passes over the nail,
the Threshold ‘hum’ momentarily
disappears (blanks).
