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.

Three accessories for attachment to the sensor:
