8. Using the detector

To inspect an area carry search head in scanning movement flat and parallel over

ground. Make sure that searched strips overlap and avoid dead spots. The detector

operates on a static mode showing metal objects by an audio alarm as long as the

search head is held over a detected object. The intensity of the signal corresponds to the

signal strength received from the target. Objects provide the strongest signal when the

search head centres over a target.

Small objects at close distance will generate a strong but short peak signal, which is

spread over a small surface. Several small objects generate a wide spread signal.

Large targets even if buried at depth will generate a signal spread over a large surface.

A - Signal shape for a small shell lying horizontally

B – Signal for a large object

Fig. 4 different detection alarm signals

If the audio signal is spread over a large area lift search coil to improve pinpointing and

determination of size and distance of the located metal.
