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  swing ing  the  searchcoil,
be care ful to keep it level with the
ground  about  1/2  inch  from  the
sur face. 

Nev er 

swing 

the

searchcoil like a pen du lum.

QUICK-START  DEMONSTRATION

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 lights or appliances,

whose electromagnetic emissions may cause interference.

e. Pivot the searchcoil back.

III.

Click on detector 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. 

a. Wave the nail over the searchcoil.

b. Press 

+

repeatedly, while continuing to wave the nail.

• Notice the change in sound.

• Sound changes from a HIGH tone to V.C.o. tones (see

page  25).

VI. Wave each object over the searchcoil.

Sweep coin flat and parallel to the searchcoil. This is how

you will usually find them buried.

a. Notice the tones and 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.

VII.

Press the 

+

button several more times until the Disc value on the

display 

=

60.

VIII. Wave the nail over the searchcoil.

a. The nail will not be detected

b. The nail has been “discriminated out.”
