Listen Through Walls Wireless; with superior UHF sensitivity contact wall microphone

This is a professional high-end Listen Through Wall unit utilising UHF amplifier technology for unsurpassed 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 20 inches thick!  The unit is so sensitive that you can not only place the direction of person/s behind any solid wall but also hear the slightest of whispers!

Furthermore, as the unit is wireless, you can simply attach the contact wall microphone to any wall surface without the need to be physically at the location and listen from some 800 meters away on the supplied Receiver!

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.

Please Note:  Listen through wall devices operate effectively on thicker solid walls as opposed to thinner walls or walls made of plaster board.  Brick walls that have a cavity layer will not work effectively.
