METAL DETECTOR

OWNER’S MANUAL

If you do not have prior experience

with a metal detector, we strongly

recommend that you:

1) Adjust the Sensitivity

to a low setting in the

event of false signals.

Always begin use at a

reduced sensitivity level; this device is

designed to work “into-the-noise”, so

expect chatter at high sensitivity.

2) Do not use indoors. This detector is for

outdoor use only. Many household

appliances emit electromagnetic energy,

which can interfere with the detector. If

conducting an indoor demonstration, turn

the sensitivity down and keep the search coil

away from appliances such as computers,

televisions and microwave ovens. If

your detector beeps erratically, turn

off appliances and lights.

Also keep the search coil away

from objects containing metal,

such as floors and walls.

3) Use a 9-volt ALKALINE battery

only.

Do not use Heavy Duty Batteries.
