The REM-DD emits an electromagnetic field around its antenna and displays any field disturbances on its 4 different coloured LED’s as well as audible tones.
The sensitivity can be adjusted by the height of the antenna before turning on the device. The field around the antenna can be disrupted by all sorts of materials and objects that can conduct electricity.
The LED’s will light up based on distance and strength of the EM Field in order of Green, Yellow, Orange and Red.
- Auto calibration when turned on.
- Audible sounds.
