OPERATION
Operation Instructions:
The HEADHUNTER PULSE metal detector is a very easy
detector to use. It's a turn on and go detector. It employs a
fully automated circuit retuning so that the threshold level
remains steady in all ground conditions. The search coil
must be in motion to maintain an audible target signal. The
following is the basic startup procedure.
1) Set TUNE control approximately to the halfway position.
2) Set FREQ (Frequency) to approximately the 4 o'clock
position.
3) Turn HEADHUNTER power ON. You should hear audio
tone. Set volume for comfortable level.
4) Re-adjust TUNE control so that you just hear the
threshold tone. Begin searching by sweeping the coil back
and forth as close to the bottom as possible. Keep coil flat
to the bottom with no rise at the end of your sweep. Pay
careful attention to the rise of the threshold sound. A
target underneath the coil will increase the threshold
audio. On very deep or low conductive targets the
threshold audio change could be very slight.
5) The settings explained above are just suggestions for a
fast start up. Maximum sensitivity is obtained by setting
the FREQ control for best response on a given target and
adjusting the threshold control so that the audio
background level is just audible.
A US nickel is a good standard to use for setting the
maximum sensitivity toward jewelry.
FREQ (Frequency) Control
This is a very unique control that is able to re-tune the
sensitivity of the HEADHUNTER PULSE (PI) detector to be
responsive to selected metals with out losing its depth
toward the selected metal. Unlike other PI detectors,
turning the frequency control back from the higher
frequency position will not result in a loss of depth for the
detector.
In its more clockwise positions, the detector will be tuned
most sensitive toward low conductive metals such as small
