Audio Recorder Accessories

Disclaimer: This product is sold to listen for such things as water leaks, rodents and more. Not designed for eavesdropping.

The ultimate professional listen through wall system that can hear sound through concrete, metal, wood, brick in fact any solid surface. Some surfaces work better than others and density / thickness can also restrict its performance.

We have received varied results as it depends entirely on the surface you use and many other factors such as distance and volume. Place the Sonde contact microphone to the surface of interest and listen it has variable gain and volume settings. You may need to experiment further with the position for better results and we can not guarantee results first time every time.

It will hear audible sound through any door or single brick / cavity walls. Anything else is not guaranteed and returns for using this beyond it's means is not accepted. Unless it is faulty not hearing through doors, windows, internal walls etc. Another serious matter is the headphones used, included is good quality earbuds but if you use noise cancelling headphones improves the sound hugely.
