IN THE FIELD TECHNIQUES

SWEEP TECHNIQUE
Sweep the search coil in a slow, consistent, side-to-side motion. The detector's
circuitry is constantly calculating the ground's mineralization. A steady,
consistent coil speed is required for the detector to make an accurate calculation.
Keep the search coil about one inch above the ground. Keep the coil even with
the ground. Do not raise the coil at the ends of your sweep.
CORRECT
TONE RESPONSE
Only dig up targets that induce repeatable tones. Each time you pass the search
coil over a possible target, you should hear the same tone. If the tone does not
repeat on each pass, varies in tone, or varies in location, then the target is
usually not of value.
Inconsistent tones are evidence of high oxidation (rusted metal) or irregularly
shaped trash items.
Note, however, that multiple tones may be evidence of multiple targets.
If you cannot pinpoint the location of a very strong signal, lift the coil higher off
of the ground until a weaker, but more precise signal is heard. Alternately,
reduce the sensitivity.
For very weak signals, try moving the coil in short, rapid sweeps, closer to the
ground.
