GROUND REJECT PROCEDURE
the GROUND REJECT control so that there is no
change or at least only a small change in the
threshold hum as you bob the coil up and down.
Start by clicking the small, center knob back to
about 8.
4. Bob the search coil up and down once again. One
of three things will happen to your threshold hum:
1) The tone will continue to get louder as you
lower the coil and disappear when you raise
it.
2) The tone will disappear as you lower the coil
and sound off as you raise it.
3) The tone will remain the same or change only
slightly.
5. If the tone remains unchanged or changes only
slightly, you are probably “Ground Balanced.” You
can fine tune, if required, with the larger knob.
6. If the tone gets louder going down and fades coming
up, continue rotating the small knob
counterclockwise until the tone change is minimal
when you bob the coil. Fine tune with the large knob.
7. If the tone fades going down and increases when
the coil is raised, rotate the small knob clockwise
until the tone change is minimal, then fine tune with
the large knob.
8. With practice, you will learn to click the small knob
counterclockwise as you bob the coil. Listen for the
change in the tone to switch from the down stroke
to the up stroke. Then, while continuing to bob the
coil, rotate the large knob clockwise until the tone
becomes even or until you hear only a slight change
on both the up stroke and the down stroke.
9. If you are having trouble ground balancing, try one
or more of the following:
1) Move to another spot in case you’re over a
piece of buried metal.
2) Reduce your SENSITIVITY setting.
3) Change your MINERALIZATION setting from
LOW to NORMAL or from NORMAL to HIGH.
