MD Noise Cancel
MD Noise Cancel adjusts the MD Sensor to reduce electrical interference.
Detectors may become noisy due to electrical
interference from power lines, electrical
equipment, or other detectors operating nearby.
The detector interprets this interference as
inconsistent, erratic detections, even when the
detector is held stationary.
MD Noise Cancel Procedure
1. Hold the Sensor Head stationary and away
from the ground and metal targets.

(24")
2. From the Detect Screen, with the MD Sensor
enabled, long‑press the Ground Balance
button to initiate the Noise Cancel process.

Nearby Detectors Procedure
If operating in close proximity with other
detectors and there is interference, the
following procedure should be followed:
1. Enable the MD Sensor on all detectors.
2. Perform Noise Cancel on each detector,
one at a time to ensure that each detector
selects a different operating frequency.
3. Perform Ground Balance on each detector
after Noise Cancel, before commencing
detecting.

3. The Noise Cancel icon and progress bar will
be shown on the LCD. A tone and/or vibration
indicates that Noise Cancel is in progress.
Do not use the detector whilst Noise Cancel is
in progress.
4. After 25 seconds, there will be an audio tone
when the Noise Cancel is complete. The
progress bar will reach 100%, and the icon and
progress bar will disappear.
