This invisible communication system consists of the spy UHF in-receiver MRF400-B, the UHF FM microphone spy transmitter SM003 and a compact walkie-talkie, with no wires on your body, no neckloop and no other accessories. You can be naked and still having a complete invisible communication with someone else, who has a compact transceiver. This communication is undetectable and non jamming!

What is it for:

This invisible communication system can be used in various situations, like politicians speech, TV presenter speaking, surveillance, presentations, interrogations or to cheat on the hardest exams.

How it works:

It is an invisible communication system and all you have to do is to put the spy earpiece into your ear canal, in order to hear your partner and to have the spy microphone hidden near you, in order to speak to your partner. The partner will use the walkie-talkie to receive your voice and to transmit information back to you. Your partner can be at a maximum distance of up to 200 meters in open field or less (max. 100 m) in a building area.

This system cannot be jammed by GSM jammers and also the receiving signal cannot be detected.

  • Wireless RF Micro earpiece FM receiver MRF400-B, with one AG4 battery
  • UHF FM spy microphone transmitter, with one battery CR2450 (only if the customs allow us)
