10.Rejection of small metal objects
and “noises” of ground
.
Often, in an area where large metal objects are searched for and
the metal detector is set to high sensitivity, many (unwanted)
small metal targets
and/or ground “noises” could be indicated.
Decreasing the sensitivity and/or use of “Silent” mode
sometimes could return acceptable results, but the Golden Mask
Deep Hunter Pro7
provides the ability to eliminate small metal
objects without reducing the sensitivity. This is accomplished
with the
“
REJECT
/GB
”
knob. The lower the value selected with
this it, smaller metal objects are detected
and ground “noises”
could be heard. After doing some tests with multiple "samples"
of different metallic objects with different sizes, you will find
which values of the
“
REJECT
/GB
”
settings are the best for your
needs.
The
“REJECT/GB” is a 10-turn potentiometer and should be
used its full 10 turns to find desired value for the small metal
pieces
and ground “noises” which have to be rejected.
11.Charging the built-in battery.
To ensure longer life of the built-in battery it must be charged
with only the supplied charger. You should regularly check the
charge level of the built-
in battery with the button “Battery Check”
(inspection is possible only when the detector is switched “
On
”)
and you must turn off the detector once the red LED "Battery"
(located in the lower right corner of the indicator) is lit.
To charge the built-in battery:
1. Turn “Off” the detector, remove the coil jack and plug in
the charger jack into the connector labeled “Charge” on the front
panel of the device.
2. Place the detector in an upright position near a power
outlet with voltage 110-240V and connect the automatic charger
into the outlet.
