OPERATION
Clockwise rotate the “SENS” control to power on the detector.
1. “DISC” function
By adjusting the Discrimination control you will be able to ignore small
pieces of metallic trash while detecting valuable targets. Discrimination
points are determined by such factors as size, shape, depth, and type of
metal and ground mineralization.
⑴
Scatter some sample targets such as coins, pull tabs and small pieces
of foil on the ground 1 to 2 feet apart.
(2) Turn the Sensitivity Control clockwise to set sensitivity to maximum.
(3) Turn the Discrimination control to counterclockwise.
(4) Put the headset on and turn on the POWER. Hold the search coil
about 2 inches above and parallel to the ground. Move it slowly over the
samples and note the LED and Audio response as you pass over each
one. Keep in mind that MD6000 is a motion detector and responds only
when the search coil is moving.
(5) Turn the Discrimination Control clockwise several points of the white
region and again pass over the targets. Repeat this process at yellow
region and so on to the red region. You will note that as you change
discrimination, MD6000 will reject some targets and continue to respond
to others. You can determine the discrimination points per your needs.
For example, the small nail discrimination may be at some point of the
yellow region and the pull-tab discrimination point at red region.
(6) Some objects such as shallow bottle caps, bent pull tabs or trash less
than 2 inches from the coil may be difficult to reject. The headset will
give out a broken signal that will usually disappear if the search coil is
raised slightly. The strong signal of a good target will just get weaker too
when the coil is raised.
(7) MD 6000 will remain silent when some objects are rejected, however
other objects may “snap, crackle and pop” as they are rejected. This is
normal responses indicating that the powerful discrimination circuitry is
doing its job.
