SubSurface LD-7 Acoustic Water Leak Detector

The LD-7 Acoustic Water Leak Detector from SubSurface Instruments is an extremely compact yet powerful device for basic water leak surveying. It has an 8-pound, palm-sized amplifier that amplifies water leak sounds by as much as 56 dB. It has a mute switch that, when pressed, activates the sound so that it can be heard through the headphones and mutes it when released to protect your hearing when moving the sensor.
