After detecting a target, do the
following:
1
.
1
.
Walk around the target in a
circle.
2
.
2
.
While
circling
the
target,
continue sweeping the search
coil across the target.
3
.
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
of
the
target's
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
tone
completely
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 identify audible and visual target feedback with
certain types of metal objects.
