FEATURES
1. SENSITIVITY - Set the sensitivity at a level that does not result in false
signals from the ground. Very strong ground may result in the symbol on
screen and a loud sound - this means the sensitivity is too high.
2. GROUND BALANCE - With the default setting, the detector will use XGB
to automatically ground balance. Tap to lock the ground balance to the
current setting. Tapping when the ground balance is locked will update
the current ground setting to what is under the coil.
3. GROUND SCAN - Hold to put the detector into Ground Scan mode. e
top bar displays the ground strength and the two digit numbers display the
ground type (phase). Useful for tracing paystreaks.

4. IRON CANCEL - Tap to silence hot rocks, trash and mineral changes in
both audio modes. Hold to adjust the Iron Cancel setting (tap the
button to cancel high-wrap hot rocks). Note that this setting may decrease the
detector’s sensitivity to very small gold, but is necessary in dicult ground
conditions.
5. VOLUME and THRESHOLD - Tap to adjust the volume with the up and
down buttons. Press and hold for one second to adjust the threshold with
the up and down buttons (“th” displays on the screen). With the volume at
levels over 8 you can enable Boost 1and Boost 2for maximum sensitivity.
6. AUDIO MODE - With the displayed on screen, the detector is in “BEEP”
audio mode (high tone = good target, low tone = bad target). e default
setting (without on screen) is a traditional All-Metal audio mode with
greater sensitivity to small targets.
7. SAT - SAT can smooth out ground inconsistencies. Press and hold for
one second to adjust it (“Sa” displays on screen, 2 is the default setting).
8. PINPOINT - Hold for non-motion pinpoint mode. In dicult ground
this mode may be aected by mineralization.
9. BACKLIGHT - Tap to enable the backlight (this reduces battery life).
10. FREQUENCY SHIFT - Hold when turning the detector on to shi
frequency (useful when there is EMI). Use and to change frequencies.
Power o to save the selection.
11. FACTORY RESET - Hold when turning on the detector. Press and hold
button when “Fd” is on screen to reset the machine to factory default.
