Notch Volume; Deep; Ground - Omega 8500 Owner's Manual

MENU ITEMS (continued)
Each target category can have its volume adjusted independently.
NOTCH VOLUME – djustable Volume Offset by Target Category
advanced setting affects the Master Volume setting and functions only in
DISCRIMINATION Mode.
Access: In Disc Mode, press and release
Press repeatedly to cycle through the various target categories. NOTCH
VOLUME will be displayed on the LCD and each category will blink when it is the
active. Select desired category and use the
volume offset. This offset will apply to the Master Volume setting. For example,
if the master volume is set at 10, and your Notch Volume offset is -3, the volume
for that target category will be at "7". If you set an offset of -5, the volume would
be "5". Notch Volume range is from 0 to -9. Changing the master volume will
change Notch Volume offsets accordingly. Make note when you set Notch
Volume offsets because there is no indication on the screen when they are active.
This allows 4 settings with varying filters that may increase depth under certain

DEEP

conditions.
D0.Fast filter. Best for target separation and searching in heavy trash. It is
the least sensitive of the Deep settings.
D1.Regular filter. Best for general conditions.
D2.Deep filter plus 60 Hz notch. This is a slower return setting that will
eliminate some EMI. The noise floor will be increased. This mode is best
used in cleaner soils and Sensitivity must be adjusted for proper use.
D3.Deep filter plus 50 Hz notch. Same as D2, but with a 50 Hz noise filter.
Access: Press and release the
to select desired mode.
Deep and Threshold relationship. The DEEP Mode settings can affect the
gain of the detector, most notable in the All Metal Mode. You may have to adjust
the threshold. If Threshold knob seems ineffective, momentarily press
reset internal offsets.
This menu item allows you to manually change the ground balance setting. It

GROUND

is active only when in the All Metal Mode. By contrast, the Ground Grab
feature automatically matches the detectors ground balance with the actual
ground phase; with GROUND you can manually adjust it up or down. This can
be beneficial, depending on the conditions you encounter. For example, if you
are in very clean soil with no mineralization, you could adjust the GROUND
setting up several digits. This would allow a slight increase the capability of the
detector. Or if you are in highly mineralized soil and hearing a lot of "chatter"
you could manually adjust the setting down several digits. This would quiet the
detector down and allow you hear desirable targets easier.
Access: In All Metal Mode, press and release

Adjust the setting while pumping the coil up and down. Some users prefer to
manually adjust ground after a GROUND GRAB operation, to fine tune it. See
the GROUND BALANCING section for more information.
