Detect. Analyze. Discover.



Our industry-leading ultrasonic recorders are engineered to help you record more bats, thanks to low-noise microphones that detect even quiet and distant echolocations, advanced triggering that records more bats, and built-in technology that detects and removes “false triggers” if they occur.  

The result? More bat calls and less time spent in analysis sifting through thousands of unusable files.
