Learn How to Pinpoint Water Leaks

The LD-12 is the professional's choice for underground water leak detection.



  • Large meter display (with backlight) of sound loudness, allowing the user to pinpoint the exact leak location.
  • Light weight amplifier, weighing only 31 ounces, with a padded carrying case and a strap.
  • Six selectable filters, split into three "low side" filters (100Hz, 200Hz, or 400Hz) and three "high side" filters (600Hz, 800Hz, or 1200Hz).
  • "Limiter" switch which cuts off all loud noises greater than 110dB. If you drop the sensor, you won't hurt your hearing.
  • "Filter-Thru" switch, which turns OFF all of the amp's filters, allowing the user to hear all sounds from 50Hz to 15,000Hz.
  • High-sensitivity ground microphone and low "electronic noise" amplifier combine to offer the very best quality sound for leak detection.
