Full spectrum bat detectors record all frequencies simultaneously to provide real time output and high quality recordings with complex call structure details preserved. This enables very precise sound analysis using manual techniques or auto-identification software. The Active Full Spectrum Bat Detectors are designed to be hand-held and are optimised for transect surveys. The range of detectors include ultrasound microphones that connect directly to your phone or tablet such as the EM Touch and Pettersson M500 as well as self-contained detectors such as the Anabat Walkabout and the Batlogger M.
