sensitive to identifying small objects and should be used for such
searches. In addition, the purpose of the round coil is to replace
the “frame” in inaccessible areas and provide an opportunity for
individual work, without an assistant. The movement with round
coils should be done very slowly.
Unlike traditional
VLF metal detectors
, using the principle of
inductive balance, the
Golden Mask Deep Hunter Pro5
can
detect metallic objects without motion. The movement is only
necessary to identify the type of metal, a speed of about one m/s
is sufficient for the discrimination system to function properly.
The search height above the ground surface with the round coils
antenna
must be constant (about 10 cm or more)
.
If you hold the coil too low or touch the ground, you will
experience faulty signals. All activities and settings recommended
for the use with “frame” coils apply as well to searches with “hand”
the round coils.
7.Indication of the presence of a metal object within the coil
area:
The signal from a metal object, located in the area of the
search coil is indicated by increasing the frequency of the sound
signal (“ticking” sound).
Most weak signals an operator is able to notice are improved by
doubling the preset frequency of the sound with the
“AUDIO
TONE On/Off”
knob. This is perceived accurately by the human
ear and therefore it needs to be set very precisely, so that the
sound frequency without the presence of a signal to be only a few
Hz (slow “ticking” sound).
Each “signal” has “start” and “end”. The
Golden Mask Deep
Hunter Pro5
has a very well expressed “zone” indication from
deeply buried metal objects with the use of a frame coil. The
length and width of this “zone” is a guide to the depth/size of the
metal objects. When this length is greater than the size of the
search antenna and has an expressed peak in the middle this
certainly indicates a deeply buried metallic object. If the signal is
