Overview  

Ultrasonic Recorder

Power extended deployments by connecting an external power cable—or record bats for up to 48 ten-hour nights on battery power alone. Maximize data capture (and minimize data collection efforts) with dual SDHC/SDXC memory card slots.

KEY FEATURES

  • Capture high-quality recordings of even distant and quiet bats via cabled, low-noise ultrasonic mics.
     
  • Record less noise with advanced triggering and technology that detects and removes “false triggers” if they occur.
     
  • Program your recorder’s location, settings, and schedule via the on-unit keypad and backlit display.
     
  • Deploy confidently in harsh elements and rugged terrain, thanks to the weatherproof enclosure.
     
  • Secure your recorder by adding a cable lock, padlock, or steel armor.
