Control Box

4.1 Rear Panel Controls

4.1.1 Power Switch
The Power switch controls the power supply from the battery to the control
box. Always switch the detector "Off" before connecting or disconnecting
the coil or battery, and when not in use.
4.1.2 Channel Switch (Ch1, Ch2, Both)
The Channel switch selects the channel used for searching: Ch1, Ch2 or
Both. Searching is usually done in the Both position which gives the
maximum sensitivity to the greatest range of targets. When detecting in
highly noisy ground, the selection of Ch1 rather than Both might improve
the stability of the threshold. However, sensitivity to certain types of targets
is reduced when using only Ch1 and is not recommended.
4.1.3 Threshold
The Threshold is used to adjust the loudness of background sound. Minelab
recommends a soft audible headphone signal which is comfortable to listen
to for extended periods.
4.1.4 Boost Switch (Shallow, N, Deep)
The Boost switch can be used to enhance the signals produced by different
types of targets.
In the Shallow position, signals from small targets close to the surface of
the ground will be amplified, allowing easier detection of such targets. This
option is best suited for quiet ground. For normal detecting conditions use
the N position which responds to all signals without boosting. The Deep
position is recommended when looking for big targets at greater depth in
noisy ground. In this mode random soil signals are smoothed, making
small changes in the audio signal from large deep targets easier to hear. It
may, however, mask some signals from very small targets near the surface.
