Buy with confidence...More than 300 sold on Ebay PinPoint Tech model 777A was specifically designed for the professional plumber for the purpose of finding water leaks. Here for the first time is an affordable high-tech instrument designed for the rapid detection of water leaks. EBay listings (unbranded/generic) in a grey case are variants of a discontinued automotive (usually loud noises) diagnostic stethoscope originally sold by Harbor Freight Tools. These resellers are selling a 10-year-old design. PinPoint Tech model 777 A is a new design optimized for the detection of very weak sounds coming from subterranean water leaks. PinPoint Tech 777 A is specially designed by an electrical engineer to specifically find water leaks with high sensitivity. The Model 777A is an original design utilizing the technology found in instruments selling in the range of thousands of dollars. This instrument will detect the faintest sounds created by escaping water in a pressurized water line. The included six page illustrated manual (exclusive to our PinPoint Tech ) describes the peculiar sounds created by a water leak and what to expect at various depths as well as the sound character from various water lines of different composition. The extremely sensitive transducer microphone (unique to our product) pinpoints the exact location of the leak in the water line. * Threshold sensitivity > -100 dBm * Texas Instrument Quad Op-Amp with an NPN-PNP complimentary audio driver * Advanced design is sensitive and covers a wide range of frequencies (100Hz TO 10kHz) * Adjustable volume control * Comfortable padded ear phones. (May be detached for use with other audio devices.) * 11-inch long-reach probe, plus a 2-inch probe. * Comes with a 9V battery, ready to put into service on arrival. * Kit includes a padded carrying case. * Very fast Priority Mail shipping ( same business day). *
