BATTERIES
The detector requires a single 9-volt ALKALINE battery
(battery not included).
Do not use ordinary zinc carbon batteries.
Do not use "Heavy Duty" batteries.
Rechargeable batteries can also be used.
If you wish to use rechargeable batteries, we recommend using a
Nickel Metal Hydride rechargeable battery.
The battery compartment is located on the back side of the housing.
Slide the battery door to the side and remove it to expose the battery
compartment.
BATTERY LIFE
Expect 20 to 25 hours of life from a 9-volt alkaline battery.
Rechargeable batteries provide about 8 hours of usage per charge.
SPEAKER VOLUME AND BATTERY CHARGE
You may notice the speaker volume drop while one battery segment is
illuminated.
With one segment flashing, low speaker volume will be very apparent.
BATTERY INDICATOR
The remaining battery life is proportional to the percentage of the battery icon
illuminated.
After the battery indicator begins flashing, expect the detector to shut off within
10 minutes.

OPERATION and CONTROLS
GROUND BALANCING
continued
When operating in ALL METAL Mode the goal is to eliminate the
sound as the coil is being pumped over the ground. In some soils,
the sound is not completely eliminated. If the ground balance
adjustment is incorrect, there will be a difference in the sound as the
searchcoil is either moving toward or away from the ground. It may
sound like you are either pulling the sound out of the ground, or
pushing the sound into the ground.
• If the sound is louder as you raise the searchcoil, increase the
ground balance setting.
• If the sound is louder as you lower the searchcoil, reduce the
ground balance setting.
NOTE: Experienced users often prefer to adjust the ground
balance to get a weak but audible response when lowering the
searchcoil. This is called adjusting for positive response.
Positive and Negative Response
The purpose of ground balancing is to adjust the metal detector to
ignore ground minerals. If the setting is incorrect, ground minerals will
give either a positive or a negative response, depending on which
direction the adjustment is off.
POSITIVE RESPONSE
If the G.B. setting is too high a number, the response of minerals will
be positive. This means that when the searchcoil is lowered to the
ground in PinPoint or All Metal Mode, the sound will get louder as the
searchcoil approaches the ground. The sound will grow quieter as the
searchcoil is raised. What, if anything, you will hear in Discrimination
Mode depends on the discrimination setting. When searching in All
Metal Mode, if ground balance is properly set to cancel the ground,
and you sweep over a positive hot rock, the rock will give a "zip"
sound similar to that of a metal object.
NEGATIVE RESPONSE
If the G.B. setting is too low a number, the response of minerals will
be negative. When the searchcoil is lowered to the ground in
PinPoint or All Metal Mode, the machine will be silent. The machine
will sound off as the searchcoil is lifted away from the ground. What,
if anything, you hear in Discrimination Mode depends on the
discrimination setting. When searching in All Metal Mode, a negative
hot rock will produce a "boing" sound after passing over it, making it
difficult to know where it is located. It will not have the sound and
"feel" of a metal object.
