The CW-20 detector is characterized by simple control and operation, power is provided by one 9 V battery. The sensitivity level is controlled by a sliding switch. This allows you to adjust the sensitivity depending on whether you are looking for small objects in your backpack or larger objects in the field. Thanks to a special discrimination setting, material that would otherwise interfere with scanning can be ignored. There are three LEDs on the back of the body: green LED - active mode, yellow - low battery, red - find, magnetic anomaly.
The on/off button has a third position for power saving mode. The button can be conveniently switched with one finger, no need to change the grip. On the other side, there is a symmetrically positioned switch to change the level of the sound signal (loud/silent with vibration). The grip area is covered with rubber, the battery compartment cover is equipped with a loop for threading the wrist strap, which effectively prevents the detector from falling directly to the ground.
