6.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, which is set with the
“AUDIO - Silent”
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
Mobile ST
has a very well expressed
“zone” indication from deeply
buried metal objects. 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 coil and has an expressed peak in the middle this
certainly indicates a deeply buried metallic object. If the signal is of a
short duration (small area), but is captured only in the central part of the
coil, then you can also expect a deeply buried metal object. Double
audible responses corresponding to the passage of the front and rear
ends of the coil over the metal object are a sure indication of relatively
small metallic object not deeply buried. After reaching a certain signal
strength (which will be indicated on the indicator
“SIGNAL”
), the
identification of the type of metal through the LEDs mounted in the
indicating
“SIGNAL”
will start to work. The red color indicates non-
ferrous metals and green indicates ferrous metals (iron). To present a
high probability of proper metal type identification, when you detect a
target, move the coil outside the target area, press the
“SMART TUNE”
button and then pass the antenna over the target from a different
direction. Repeat as many times as you want to identify the type of the
metal more securely. With a little experience, anyone can learn to
recognize the nature of the various signals, which will lead to better use
of the great capabilities of the
Golden Mask Deep Hunter Mobile ST.
