20 A Simple Detecting Exercise
Detector Sounds (cont)
The Audio Response is the sound produced
by the detector when a target is detected
and not ‘rejected’. When using Coin and Coin
& Jewellery Mode, a highly conductive target
(e.g. a large silver coin) will generally produce
a high-pitched tone and a low conductive
target (e.g. foil) will generally produce a lowpitched
tone. Large targets or targets close to
the ground surface emit louder signals.
When a ‘rejected’ target is detected, the
Threshold ‘blanks’ (becomes silent), indicating
that a target is located underneath the coil,
but has been rejected by the Discrimination
Pattern (p. 30). Blanking is a useful way
of distinguishing between desired and
undesired targets.
Note: As the coil passes over the nail, the
Threshold ‘hum’ momentarily
disappears (blanks).
Large objects close to the coil may Overload
the detectors electronics. When this happens,
Safari displays an Overload message and
emits an Overload sound until the coil is
moved away from the source of the overload.
Overloading is not harmful to the electronics
of the detector.
It is important to understand the sounds
produced when you make a valid or invalid
button press. You will usually encounter these
sounds while adjusting settings via the Main
Menu.
Tip: When detecting do not wear steel-toed
boots or shoes with metal eyelets. These can
send conflicting signals to your detector.
