GROUND BALANCING

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™ and MANUAL GROUND balancing feature allows the
user to more precisely calibrate the detector's internal circuitry to the specific
ground you are searching.
We therefore recommend that you use GROUND GRAB™ 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.
AUTOMATIC GROUND BALANCING PROCEDURE USING GROUND GRAB™
1. Find a spot of ground where there is no metal present.
2. Hold the detector with the searchcoil about one foot
above the ground.
3. Enter the GROUND GRAB™ Mode.
4. Push and hold
5. Physically pump the searchcoil and detector up and
down over the ground.
Lift it about 6 inches above the ground and lower it to within
1 inch of the ground, about once or twice a second.
6. A 2-digit ground value will appear on the display. This is the
Ground Balance setting.
7. When the 2-digit ground value stabilizes, release the button.
Note: GROUND GRAB™ will not automatically balance over highly con-
ductive soils, such as a wet salt water beach. Automatic balancing is not
possible in soils with ground values less than 40. The screen will display "--"
and an alarm will sound if over metal or in ground with a value less than 40.
MANUAL GROUND BALANCING
In most situations, it is preferable to use GROUND GRAB™ to automatically
ground balance. Generally, it is best to first let the detector automatically
cancel interference from ground minerals. However, for gold prospecting,
searching on a wet saltwater beach, or searching in an area with so much
metal trash that there is no clean ground for the detector's internal computer
to sample, we recommended that you manually ground balance. Manual
ground balancing requires a bit of skill, acquired with some practice.
