Listen Through Walls Stereo; with superior sensitivity contact wall microphone

This is a professional high-end Listen Through Wall unit utilising extremely sensitive duel stereo amplifier technology for superior listening quality.  Constructed in the finest of materials and designed to government standards - the quality and engineering is truly magnificent enabling the user to listen through solid concrete walls up to 36 inches thick!  The unit is so sensitive that you can place the direction the person/s behind any solid wall.

This LTW device is equipped with an automatic sound filter which helps eliminate unwanted background noises plus a sound limiter for reducing any possible foreground bangs that could damage your ear drum.  The transducer casing is made of full aluminum and coated with special plastic providing an excellent shielding against radiation such as GSM or ISM interferences.
Unlike many LTW devices, this unit does not use a contact pin therefore, can easily be attached to the wall by use of our 'magic' putty which leaves no marks or residue once removed.
