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. Expect chatter or

internal noise 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.
