A mini spy bug for room or body surveillance NANO SIZE, featuring a very long microhone. This listening device is designed especially for places where it is difficult to hide a simple bugging device, for example in a car, in a small properties or in offices. Sometimes it is difficult to conceal a spying device due the battery size, however power and distance is required. This is the ideal bug.
It is built using a small size microphone, a 1 meter (3.3 ft) special thin cable and a powerful listening device, spying transmitter.
The spying bug transmitter uses one battery (Alkaline, 9V). Transmitting on the UHF band, for achieving high capabilities and maximal privacy. The range is approx. 200m on urban area and up to 700m (line of sight). Maximal drawn current: 20mA. Maximal output 12Bm. Super sensitive, miniature, just 4 mm diameter microphone. For the best audio, it is required an UHF receiver (we sell 3 UHF receivers) or an UHF scanner. One of the best listening devices on the market!
