The LD-8 features excellent sensor sensitivity, leak sound amplification, and audio clarity. Selective noise-cancelling notch filters help reduce hum from nearby transformers, power lines and the like. This audio clarity lets you use your own ears to determine the location of the leak. In addition, where ears fail, you can reference the two-digit display, to compare the loudness of leak sounds at nearby locations.
The LD-8 includes both a short contact rod for listening at hydrants, and a long contact rod for listening at below-grade meters and valves.
Some other features include an amplifier with push on/off switch, volume control, two digit display of loudness, and three-range sensitivity switch. The stereo headphones are made from soft and plush leather, ensuring comfort for the entire day. The sturdy but lightweight carrying case weighs 10 lbs and fits neatly behind a seat.
