The CW-20 detector is characterized by simple operation and handling, powered by one 9 V battery. The sensitivity level is adjusted using a sliding switch. This allows you to adapt the sensitivity depending on whether you are looking for small objects in a backpack or larger objects in the field. Thanks to the special discrimination setting, you can ignore materials that would otherwise interfere with scanning. On the back of the body there are three LEDs: green – active mode, yellow – low battery, red – detection, magnetic anomaly.
The on/off button has a third position for power-saving mode. The button can be conveniently switched with one finger, without changing your grip. On the other side there is a symmetrically placed switch for changing the level of audio signalling (loud/silent with vibration). The handle area is covered with rubber, and the battery compartment cover is equipped with a loop for threading a wrist strap, which effectively prevents the detector from falling directly to the ground.
