The LD-10 leak noise detector enables the user to listen for the noise of a leak through highly sensitive sensors (often called a ground "microphone")

The patented sensitive microphone detects the noise of a water leak that is transmitted along pipes, valves, hydrants and through the ground. The closer you are to the leak, the louder and clearer the leak noise, and the higher the signal displayed on the LD-10's LED meter.

• Light-weight, compact unit, shipped in an ABS injection molded case, with all accessories.
• Six selectable filter frequencies, for 9 different noise-filtering combinations. Frequencies range between 100 and 1200 Hz.
• Select filter frequency ranges to tune in the leak, and tune out unwanted noise below & above the actual sound of the leak.
• Search for leaks in PVC pipe in the lower frequencies, and leaks in steel or cast iron pipes in the higher frequencies.
• Highly sensitive, patented ground microphone.
• Super magnet for steel and iron pipes and hydrants.
• Improved microphone cable and strain relief with a patented wind noise dampener.
• Hand-held microphone switch to protect hearing while moving and positioning the microphone.
• LED color display meter. Great night visibility.
