Product Description
The LD-7 Acoustic Water Leak Detector from SubSurface Instruments is a compact, easy-to-use solution for basic water leak surveys and pinpointing. Designed for occasional or entry-level users, the LD-7 features a palm-sized amplifier that weighs just 8 pounds and delivers up to 56 dB of amplification to isolate leak sounds clearly.
Its push-button mute switch protects the operators hearing by muting sound during sensor repositioning and activating it only when needed. The system includes a 3-point ground plate for pinpointing leaks on pavement or concrete, plus a magnetic base and contact rod for surveys at hydrants, valves, and meters.
Advanced filtering blocks out environmental noise such as wind, traffic, and nearby machinery. With 5 high-frequency filters, 3 low-frequency filters, and 2 notch filters, the LD-7 ensures cleaner audio in challenging environments. The included stereo headphones feature soft leather ear pads for comfort during extended use.
Powered by two AA batteries, the LD-7 offers up to 30 hours of continuous operation. All components come packed in a heavy-duty ABS case compact enough to store behind a truck seat or in a small cabinet.
