Operating Instructions:
The
HEADHUNTER
metal detector is one of the
simplest metal detectors to use. It employs fully
automated, ground balanced motion-discrimination
circuitry. The searchcoil must be in slight motion to
maintain audible target signal. The following is the basic
startup procedure for Diving & Wading.
1.
Turn
HEADHUNTER
power ON. Set Volume to level
where you can hear target signals comfortably. This can
be accomplished by passing a coin back and forth under
the searchcoil. Regulator bubble noise can reduce your
hearing range and volume level should be increased
accordingly.
2.
Turn the Sensitivity control fully clockwise to the
maximum level. If you hear chatter or static, reduce
level until no interference is audible. In salt water, it may
be necessary to reduce sensitivity. Your
HEADHUNTER
is
equipped with a quality "stay put" segmented
potentiometer for the Discrimination control. Sensitivity
and Volume are continuous turn controls. The Sensitivity
and Volume adjustments should be made according to
how your detector reacts in salt and fresh water.
3.
Next adjustment will be setting the Discrimination level.
After learning where unwanted items will be
discriminated out, you can adjust this before entering
the water. If you want to change Discrimination levels
once operating in water without having to view the
control, just simply count knob clicks from the "0"
position. Again, bench testing will teach you what click
count setting certain objects are eliminated from audio.
4.
Swing your coil back and forth slowly over the water's
bottom. Keep the coil as close to the bottom as
possible. Solid sounding audio signals should always be
investigated. Pinpointing a target is accomplished by
raising the searchcoil off the target and slowing the
sweep until the audio signal is centered under the coil in
opposing sweep directions.
5.
Retrieving targets submerged in water is more difficult
than on land or wading. Some hunters just fan the
water to move the sand while others will carry a special
digging tool. Always carry a small "goody" bag to deposit
and transport your finds. Please remove and dispose of
all trash you find. No one likes digging it up more than
once!
