SubSurface offers a professional water leak detector with a standard cable. A large meter display (with backlight) of sound loudness, allows the user to pinpoint the exact leak location. The unit includes a lightweight amplifier (31 ounces) with a padded carrying case and a strap. The locator has six selectable filters, split into three "low side" filters (100Hz, 200Hz or 400Hz) and three "high side" filters (600Hz, 800Hz or 1200Hz). A “Limitter" switch which cuts off all loud noises greater than 110dB. A "Filter-Thru" switch turns off all of the amp's filters, allowing the user to hear all sounds from 50Hz to 15,000 Hz. High-sensitivity ground microphone and low "electronic noise" amplifier combine to offer quality sounds for leak detection. Three accessories for attachment to the sensor are included: a ground plate for pinpointing on streets/slabs; a magnet base for surveying hydrants/valves; and a contact rod for surveying at meters/fittings. 920.347.1788,
