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 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.”
SEARCHCOIL MOVEMENT
When swinging the searchcoil,
be careful to keep it level with the
ground about 1/2 inch from the sur-
face. Never swing the searchcoil
like a pendulum.

CORRECT
I. Supplies Needed
• a Nail • a Zinc Penny (dated after 1982)
• a Nickel • a Quarter
II. Position the Detector
a. Place the detector on a table,
with the searchcoil hanging over
the edge. Or better, have a friend
hold the detector, with the
searchcoil off the ground.
b. Keep the searchcoil away from
walls, floors and metal objects.
c. Remove watches, rings and
jewelry.
d. Turn off fluorescent lights,
appliances and cell phones
whose electromagnetic emissions may
cause interference.
e. Pivot the searchcoil back.
III. Click on power with the left knob. Set the Gain at the 12:00
position for this demonstration.
IV. Click the right knob to the left to the DISC setting.
V. Press until “VOLUME” is highlighted on display.
a. Press or until number on display is 12.
b. Wave the nail over the searchcoil. Notice volume.
c. Wave a coin over the searchcoil. Notice louder volume.
d. Enter the menu/volume control again.
Use and to change volume as you wave nail over
searchcoil. Notice the volume changing.
VI. a. Set volume at 20. Wave the nail over the searchcoil.
b. Press until DISC is highlighted on display.
c. Press repeatedly, while continuing to wave the nail.
The nail will be discriminated out. The Target-ID at which it is eliminated
depends on the size of the nail.
VII. Wave each object over the searchcoil.
Sweep coins flat and parallel to the searchcoil. This is how
you will usually find them buried.
a. Notice the 2-digit Target-IDs for each object.
b. Motion is required.
Objects must be in motion over the searchcoil to be
detected in this mode.
