Professionally made Spy Audio Transmitter Listening Device
This sub miniature listening device is professionally made for discrete listening of conversations within rooms up to 100 meters away. The microphone is of a high quality and omni directional for all round sensitivity, therefore does not need to be directed to the sound source. It will pick up conversations as far as 30ft away and discreetly transmit it to the mini pocket receiver where you can listen to the conversations in real time, for the most discrete covert listening. The transmitter can work up to 100m away from the receiver in open air. Just simply connect to a 9V battery no special set-up required.
