The next, very important control is the normal /
heavy soil switch. As we already mentioned, for
mass searching, and for maximum quality of
operation and detection depth on the most soil
types we would recommend operation in the
normal mode.
In the normal position of the switch(Figure 7) the
detector will be deeper in the ground.
Sometimes, while operating on very heavy and
wet grounds in the
normal mode of operation is
possible to experience the so called affect of the
hole. especially when using bigger sized coils.
While passing the coil over an open hole in the ground, you could hear audio
signal from the detector, even if in the hole there is no metal object. To avoid
this unpleasant affect, please, switch to the
heavy soil mode of operation.
Tone 1/tone 2 switch. This switch does not affect the quality of operation and
the sensitivity of the detector. It is for a choice of the frequency of the sound ,
which will be heard from the detector’s speaker when passing over a metal
target. In
tone 1 position the frequency of the sound is 1140 Hz (high pitched
sound). In tone 2 position the sound is with a 570Hz frequency (low pitched
sound). Of course, every operator chooses the sound he prefers.
Pinpoint button. Once you have decided to dig
you should find the exact location of the metal
target in the ground. Move the coil off to one
side of target area, press and hold the
pinpoint
button, and slowly, carefully keeping the coil at
a constant height over the ground surface, pass
the coil over the spot you believe the target to
be. A continuous tone will be heard as long as
the coil is over the target. The loudest and the
highest pitch sound coming from the speaker
indicates the exact center of the target.
