Comprehensive Operating Manual & Guide to Metal Detecting
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 only.
Do not use Heavy Duty Batteries.
