QUICK-START DEMONSTRATION
I. Supplies Needed
• A Medium-Size Nail
• A Quarter
•
A Nickel
• A Zinc Penny (dated after 1982)
II. Position the Detector
a. Place the detector on a
table, with the search coil
hanging over the edge.
(or better, have a friend
hold the detector, with
the coil off the ground)
b.
Keep the search coil
away from walls, floors,
and metal objects.
c. Remove watches, rings and other jewelry or metal objects from
hands and wrists.
d. Turn off appliances or lights that cause electromagnetic
interference.
e. Pivot the search coil back toward the detector body.
III. Power Up
Press the ON touchpad.
The detector will beep
several times and the
sensitivity setting will
be indicated on the
right of the display. Two
illuminated segments
indicates 3/4 sensitivity.
IV. Wave each Object over the Search Coil
(
pass the flat side of the coins
parallel to the coil)
a.Notice a different tone for each object.
Low Tone:
Nail
Medium Tone:
Nickel & Zinc Penny
High Tone:
Quarter
b.Motion is required. Objects must be in motion over the
search coil to be detected.

IN THE FIELD TECHNIQUES
When pinpointing a target, try drawing an “X”,
as illustrated, over where the tone is induced.
PINPOINTING
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.
TARGET DEPTH ESTIMATION
After verifying a desirable
target, pass the coil again, but
raise the coil 1” over the
ground, progressively higher
with each sweep. Note the coil
elevation at which the signal
disappears. With practice, you
will be able to approximate
target depth.
