Trying out the detector
Figure 5.2
Dont try this at home!
If you attempt to begin detecting while you are inside your home,
you will quickly find that there are many metallic objects (such as
nails or reinforcing in the floor) which will result in almost
continuous detection. There will also be interference from TV sets
and other household appliances. Placing the sensitive detector
coil near large metallic objects can result in temporary saturation
of the sensor, meaning that it then cannot detect small objects.
Therefore it is best to turn your detector off and head outside, as
far away as you can from sources of electromagnetic disturbance.
Sweeping the coil
The Explorer II will perform at its best when the coil is kept in
close proximity to the ground. This will increase detection depth
and response to small objects. Becoming practised at sweeping
the coil is very important, as variation in coil height at the end of
each swing can cause confusing sounds and reduce detection
depth. Each sweep of the coil should overlap the last one (Figure
5.2). This will ensure good ground coverage.
You think youve found something?
When an object is detected, the Explorer II emits an audio
response and visually displays a target classification on the
control panels screen.
Before you attempt to pinpoint or recover the object which
is explained later in this chapter it is vital you understand
how to interpret these audio and visual responses.
This is explained over the next few pages.

Audio Overload
Sometimes it is possible that a
large object close to the search
coil will overload the detector’s
electronics. When this happens,
the Explorer II emits a low warble
which will repeat until the coil is
moved away from the source of the
overload.
