The detector requires a single 9-volt
ALKALINE
battery (battery not included).
Do not use ordinary zinc carbon 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 3-segment battery indicator has 4 stages of indication.
These indications are accurate for a 9-volt alkaline battery.
Segments Illuminated
Battery Voltage
3 -segments
more than 8.3 volts
2 -segments
more than 7.0 volts
1 -segment
more than 6.2 volts
1 -segment flashing
less than 6.2 volts
After the battery indicator begins flashing, expect the detector to shut off
within 10 minutes.
A rechargeable battery will usually illuminate all segments throughout
most of its useful charge. But as soon as it drains to the 2-segment level,
it will then discharge very rapidly.

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 one inch from the
surface. Never swing the coil like
a pendulum.
