SEARCH TECHNIQUES
Target Verification
After detecting a target, do the
following:
1. Walk around the target in a
circle.
2. While
circling
continue
searchcoil across the target.
3. Sweep once every 30° or 40° of
the circle.
If the tone does not change
and the Target-ID value is
consistent as you circle the
target, you can be highly
confident
identification.
If the tone or Target-ID
changes as you circle the
target, you may have multiple
targets or an irregularly shaped
object.
If
the
disappears at different angles, the target may be trash or a low-
value metal.
If you are new to the hobby, dig all targets. With practice in the
field, you will soon be able to correlate audible and visual target
feedback with certain types of metal objects.
Pinpointing in Discrimination Mode:
1. Sweep over target in narrowing side-to-side pattern.
2. Take visual note of spot on ground where "beep" occurs.
3. Step 90° to the side of the target.
4. Sweep searchcoil over same area, at 90° to 1st sweep pattern.
5. This pinpoints the target location with an "X."
