The AquaTest T10 is both an electroacoustic Listening Stick  (water leak pre-location sometimes called "Valve Bashing") AND ground microphone combined, designed to find and locate water leaks in mains water distribution networks and supply pipes.

The AquaTest T10 is used single handed with the receiver and microphone combined in one unit. The digital wireless  headphones are activated not by the usual push button but by a touch free sensor, simply place your finger in the activation area and the T10's headphones are activated, take your finger away they are deactivated. The water leak noise level (volume) that you are hearing are shown on an liquid crystal display.

The Sewerin Digital Radio (SDR) radio allows sound to be transmitted, with no interference or loss, from the T10 to the SDR headphones meaning there are no cables to the headphones to restrict your movements and  get in your way.

The inbuilt frequency filters allow the user to filter out unwanted noise frequencies and to concentrate on the water leak noise.
