CSI Pro™ 35
Discrimination bench test:
A similar test procedure can
be used to better understand how to set iron discrimination
levels. Pass the iron nail across the searchcoil. With the
factory preset level of zero (0) Iron Discrimination, the nail
produces a Low Tone. If the iron nail registers up to a 26
on the Digital Target ID, use the IRON DISC pushbuttons to
move the Iron Discrimination setting up to 26. Pass the iron
nail across the searchcoil again to verify that it has been
eliminated. If not, raise the Iron Discrimination setting a little
higher using the (+) IRON DISC touchpad until the iron target
no longer produces an audible response.
Iron Audio bench test:
Next, remain in ZERO mode
with your Iron Discrimination level set to remove the iron
nail tested in the example above. Press the IRON AUDIO
pushbutton and pass the nail across the searchcoil again to
hear the distinctive iron sounds. The distinctive Low-medium-
Low response indicates that the target is unmistakably iron.
Flat iron objects like bottle caps or steel washers can
appear to be good conductive targets to detectors. To test
the
CSI Pro
's advanced iron recognition abilities, conduct
another bench test with an iron bottle cap. (Follow the steps
as outlined on page 33 of the previous "Iron Audio" section.)
Final tip:
Record the results of your bench tests and refer
to them when hunting in the field. knowledge of the audio
characteristics and the Iron Audio feature of the
CSI Pro
can
reduce the amount of trash targets that are dug.
