IN THE FIELD TECHNIQUES

(motion modes only)

When pinpointing a target, try drawing an “X”,

as illustrated, over where the tone is induced.

PINPOINTING IN MOTION MODES

Accurate pinpointing takes practice
and is best accomplished by
“X-ing” the target area. 

1.

Once a buried target is indicated
by a good tone response,
continue sweeping the coil over
the target in a narrowing
side-to-side pattern.

2.

Take visual note of the place on
the ground where the “beep”
sounds.

3.

Stop the coil directly over this
spot on the ground.

4.

Now move the coil straight
forward and straight back
towards you a couple of times.

5.

Again make visual note of the
spot on the ground at which
the “beep” sounds.

6. 

If needed, “X” the target at

different angles to “zero in” on
the exact spot on the ground at
which the “beep” sounds.

COIL MOVEMENT

When swinging the coil, be
careful to keep it level with the
ground about 1/2 inch from the
surface. Never swing the coil like
a pendulum.

VI. Wave the Nail over the Search Coil

a. The Nail will not be detected.
b. The Nail has been "Discriminated Out."

VII. Press the  “DISCRIMINATION-

” touch pad twice.

Five “R”s are now displayed.

VIII. Wave all objects over the

Search Coil

The Nail and Pull-Tab will not be detected.
The other objects will be detected with their own distinctive tones.

IX. Press the NOTCH touch pad.

A flashing “R” will appear
under the Iron-1 segment.

X.  Press the DISCRIMINATION 

touch pad three times.

The flashing “R” will move to the 5¢
segment.

XI. Press the NOTCH touch pad again.

The “R” will disappear under 5¢.

XII. Wave the nickel over the search coil. 

The nickel is detected.

XIII. Wave the penny over the coil.

XIV.

Press the ZAP touch pad.

An “R” will appear.

XV. Wave the penny over the

search coil again.

The penny (the most recently
detected item) is eliminated
from detection.

XVI. Press the PINPOINT touch pad.

Hold one of the metal objects motionless over the search coil.

• All Metal objects are now detected.
• Depth and Target indicator do not illuminate in this mode.
• One monotone sound indicates the presence of any type of metal.
