A Simple Detecting Exercise

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 low-

pitched 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 conicting signals to your detector.
