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. Power Up
Press .
IV. Wave each object over the searchcoil.
a. Notice a different tone for each object:
Bass Tone:
Nail
Low Tone:
Nickel
Medium Tone:
Zinc Penny
High Tone:
Quarter
b. Motion is required.
Objects must be in motion over the searchcoil to be detected in this mode.
V. Press
twice to enter the DISC. LEVEL program.
Then press
.
a. The word “IRON” disappears from the display
VI. Wave the nail over the searchcoil.
a. The nail will not be detected
b. The nail has been “discriminated out.”
VII. Press
four more times.
a. The words FOIL, NICKEL, PULL-TAB, and S-CAP+ disappear.

4. GROUND GRAB
®
COMPUTERIZED GROUND BALANCING
All soils contain minerals. Signals from ground minerals interfere with the
signals from metal objects. All soils differ, and can differ greatly, in the
type and amount of ground minerals present. This detector incorporates
ground balancing algorithms which eliminate interference caused by the
ground minerals found in most soils.
The GROUND GRAB
®
Computerized Ground Balancing feature allows the
user to more precisely calibrate the detector’s internal circuitry to the specific
ground you are searching. We call this calibration process
ground balancing.
We therefore recommend that you use GROUND GRAB
®
Computerized
Ground Balancing to most accurately calibrate the detector to the specific
ground conditions where you are hunting. It is a quick and automated
process, and will instantly grab the ground reading of any patch of ground
you are standing over. This process will maximize the detector’s target
identification accuracy and depth detection capability.
The Process is as follows:
1. Find a patch of ground which is free of metal.
Use the DISCRIMINATION Mode, with no targets discriminated out.
2. Enter the
ALL METAL Mode
of operation.
3. Hold the detector with the searchcoil a foot or two above the ground.
4. Press-and-Hold .
The GROUND GRAB
®
Computerized Ground Balancing line is
illuminated.
5. Lower the searchcoil down to within 2 inches of the ground.
6. After successfully ground balancing, release
.
You have successfully ground balanced after a 2-digit number appears in
the middle of the screen. After 3 seconds with the same 2-digit number
displayed, you will hear a repeating high tone, indicating that ground
balancing was successful.
If the detector is not able to ground balance, “ _ _ ” appears, a low-pitch
warning sound alarms, and the message “Raise Coil” is illuminated. You
could be over a piece of metal. If so, find another patch of ground. The
detector will also not Ground Grab
