SEARCH TECHNIQUES

Target Verification
After detecting a target, do the
following:
1. Walk around the target in a circle.
2. While circling the target, continue
sweeping the 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 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 metal detecting,
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."

Do not twist the Cable or Plug. Turn Locking Ring
only. Use minimal finger pressure to start the
threads. Do not cross-thread. When the Locking
Ring is fully engaged over the threaded connector,
give it a firm turn to make sure that it is very tight.
When the Locking Ring is fully engaged over the
threaded connector, it may not cover all of the
threads.
Tighten both LOCKING COLLARS.
