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.

BATTERIES 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 for-

ward 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 pendu-

lum.
