BENCH TESTS
As you operate the CSI 250 you will quickly grow
more efficient in its use. You can also conduct
bench tests to become more familiar with your
detector’s operation. To conduct a bench test:
1. Place the searchcoil on a flat, non-metallic surface
that’s several feet from other metallic objects.

Method 2 - Press the + or - DISCRIM pushbutton
to position the Upper Scale cursor above the
Lower Scale segment corresponding to the target
to be detected or ignored. Determine the target you
would like to accept or reject and press the ELIM
pushbutton.
Sensitivity
The CSI 250 has 8 sensitivity settings for achieving
maximum depth. However, you many not always be
able to operate at full sensitivity. Electromagnetic
interference, irregular ground mineralization and
other environmental conditions may sometimes
require that you operate at reduced detection
sensitivity.
Use the + and - Sensitivity pushbuttons to adjust
sensitivity to the appropriate level, usually as high as
possible while maintaining stable operation.
