5. Do not use (or leave) the detector in a humid environment, wet bushes, snow and/or
water – the electronic block could be damaged (it is not sealed). When you connect the
antenna to the electronics, you should prevent the ingress of water or moisture in and
around the contact pins of the connectors.
6. Work with the detector in industrial areas and places with a large amount of metal
junk in the soil, and with presence of industrial electromagnetic interferences, can lead
to instability and/or inability to work. This requires reducing the sensitivity of the device
with the "SENSITIVITY" knob, which will reduce the depth of detection, but this is the
only way to achieve stability in such conditions.
7. After extensive work with the detector, with repeatedly accession and separation of
the search coil (antenna) connector, the connector could be damaged, that's why these
activities should be carried out very precisely and carefully. Contact points of the
connector should be kept clean and dry.
8. If the indicator "SIGNAL" shows a negative value (arrow deviates to the left of zero)
after lifting the antenna from the ground, this means that under the antenna was a
metallic object. In such case, move the antenna to another location, turn on the device
again, press briefly the "RETUNE" button and start the search.
9. Switch-on the detector for about 15 minutes in the area of search before starting to
search for metal objects. During this time the Deep Hunter electronics are self-adjusted
to the ambient temperature and the detector reaches its optimum parameters.
10. Do not attempt to use the detector after the built-in battery is discharged. This can
result to damage of the battery and/or the electronics.
