The AR180-EXT is a professional quality ultrasonic receiver that is designed for ultrasonic recording and acoustic analysis. It employs a directional, wide bandwidth ultrasonic element along with ultrasonic to digital conversion technology to produce a high quality, digitally sampled, acoustic stream that is injected directly into a laptop computer or field recorder to perform ultrasonic monitoring, and analysis.

The AR180-EXT system is specifically designed for bat monitoring applications which require that the detector is mounted quite a distance away from the recording device. The system consists of an ultrasonic microphone element and a ultrasonic digitizer unit. The two units are separable up to 250 feet and are connected using industry standard CAT-5e or CAT-6 cable.

The AR180-EXT is shipped with a 20 foot cable.  Longer cables can also be supplied, but with an additional charge
