This device removes any barriers between you and object you are tracking. With it you can listen to and if you have a recorder you can record the conversations directly through the wall. Whether the wall is brick, concrete, plasterboard or other you will be able to hear crystal clear what is happening on the other side.
For even better sound quality special headphones are provided to make sure all of what is said on the other side will be comprehensive.
The device has a lithium-ion battery that allows 50 hours of nonstop operation per charge.
There are four levels of sensitivity and a knob for adjusting the sound volume.
All accessories of the listening device are packed in a convenient metal briefcase.
