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).

“Limitter” 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.
