Prizm™ 6T
A.
VCO (Voltage Controlled Oscillator) Pinpointing. VCO produces a
progressively higher pitched tone as the target signal becomes progres-
sively stronger during pinpointing.
Press and hold P/P to activate the pinpoint mode. Then press TONE ID
to enable or disable VCO pinpointing.
VCO is a feature that only operates in the Pinpoint and All Metal
modes. When ON, the stronger the target response, the higher the
pitch of the sound.
VCO is an excellent aid to pinpointing. Slowly “X” the loop over the
suspected target area. The highest pitch sound indicates the center of
the target.
At the point of the highest pitch sound, the target depth feature indi-
cates its most accurate depth.
7. Trac Lock (Ground Tracking Lock) locks the ground rejection level
at its current setting, indicated on the right side of the display with a
padlock icon. Unusually inconsistent grounds (spotty bits of significant
mineral among lower or higher mineral base) can cause difficulties for
the automatic system. The ‘average ground” setting chosen by the
automatic system may not be ideal for eliminating ground noise and
providing reasonable stability (few enough signals to recognize metal
targets). Allowing the 6T to track to a troublesome spot of mineral
(sweeping or pumping over it until it no longer responds) then locking
the Trac feature at that level, allows greater overall performance in
VCO audio. VCO audio varies the pitch of the beep as the search coil
nears the center of the target allowing improved pinpointing and better
multi target separation. VCO only performs when operating in the P/P
and All Metal mode. VCO will not function in the DISC mode.
