Chapter 4 GM24k Controls Controls Sensitivity Control With the SENSITIVITY control, you increase the signal strength coming from the ground. You might expect increased signal strength to always find more nuggets at greater depths. However, high Current ground mineralization will “bounce” the signal back and mask good targets. -

Chapter 4 GM24k Controls Sensitivity Adjustment (cont’d) 5. The object of increasing the SENSITIVITY is to get the maximum available depth from the detector WITH-OUT causing the overload message to appear, which indicates an overload of the circuit. 6.In addition, any increase in SENSITIVITY adjustment should NOT BE at the expense of maintain- ing a smooth and constant THRESHOLD “hum”. -

Chapter 4 GM24k Controls Target ID The GM24k features two types of Target ID. The most obvious is the large numbers displayed in the center of the screen when the coil passes over a target. These two digits represent a scale from 0 to 99, with higher numbers equalling a higher chance that the target is non-ferrous. -
