Golden Mask Deep Hunter Pro5 

is a professional treasure and

relic hunting metal detector designed primarily to detect deeply
buried metal objects and discriminate between ferrous and non-
ferrous metals.

Golden Mask Deep Hunter Pro5 

is an advanced pulse induction

metal detector, with newly developed full range 

“flash automatic

ground   exclusion   balance”,   “trash   reject   control”  

and

discriminate   between   ferrous   and   non-ferrous   metals.   Its
powerful performance is based on the very high quality state-of-
the-art sophisticated electronics.

Golden   Mask   Deep   Hunter   Pro5  

can   significantly   reduce   the

negative effects  of power  line and other electrical interference.
This detector

  

offers remarkable stability, sensitivity and accuracy

that is achieved with the use of very simple and intuitive settings. 

Pulse induction is based on  the processing of short and intensive
magnetic pulses which are emitted by means of a search coil.
Those   magnetic   pulses   produce   electrical   eddy   currents   in
conducting   metallic   objects.   Eddy   currents   will   be   stored   in   a
metallic object around of the search coil but will quickly die away
after the magnetic pulse emitted by the search coil has ended.
The eddy currents and their time delay are read by the receiving
phase by the search coil which now acts as a receiving coil. The
received signal is amplified to drive an audio response via built-in
loudspeaker or headphones when a metallic object is within the
field of the search coil.
