OWNERS MANUAL
If you do not have prior experience with a metal
detector, we strongly recommend that you:
1) Adjust the Gain to a low
setting in the event
of false signals.
Always begin use at
a reduced Gain level;
increase Gain only after
you have become
familiar with the detector.
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 Gain down and keep the searchcoil
away from appliances such as computers,
televisions and microwave ovens. If your
detector beeps erratically, turn off
appliances and lights.
Also keep the searchcoil away from
objects containing metal, such as
floors and walls.
3) Use a 9-volt ALKALINE battery.
Do not use Heavy Duty Batteries.
