- "BOOST" - switch the additional amplification of the received signal:
- "OFF" - normal depth of detection;
- "ON" - about 20% extra depth of detection.
(After turning the switch at "ON" position, the "RETUNE" must be pressed);
- "SIGNAL" – analogue meter indicating the strength of the received signal and the level
of charge of the built-in battery; there are embedded 3 LEDs for indicating the type of
the metal and the condition of the battery:
- "Fe", "n-Fe" - LED indication of the type of metal -
green for ferromagnetic metals and red for non-ferromagnetic metals;
- "Battery!" - LED for indicating less than 10% residual charge of the built-in
battery, whereby it must be loaded (see #11);
- "Battery Check" - button to check the level of battery charge. This button can be used
at any time. When the arrow is in the red sector, the battery should be charged!
4. Eliminating the influence of soil (ground balance).
Golden Mask Deep Hunter Pro3 uses full range automatic ground balance based on
the "flash auto ground balance" system - unique to this model. It doesn't need any
settings and continuously rejects the signals generated by the soil during the searching.
In extremely high mineralized soils the noises can be reduced by the "TRASH" control
knob or by reducing the sensitivity of the detector - decrease the "SENSITIVITY" value
and/or switch Off the "BOOST".
5. Search for metal objects with frame search coil
Golden Mask Deep Hunter Pro3 is designed to be used with big size search coils type
"frame". This is the main way to search for deeply buried metal objects. The search coil
is moved slowly at a constant height (10 cm or more ) above the ground. Coils of type
"frame" are delivered in the form of "coil-cable loop" in length corresponding to the
respective size of the supporting frame and a set of plastic pipes and fittings for
assembling the supporting structure of the frame.
