USG 116Hnb principle

Principle of the UltraSoundGate 116Hnb recording system

What are the advantages of Avisoft-UltraSoundGate 116Hn over other bat detectors?

  • Increased dynamic range (16 bit A/D conversion instead of 8 or 12 bits).
  • Unlimited continuous recording time (the only limitation is the size of the computer harddisk).
  • Realtime spectrogram display during recording (can also be disabled).
  • Acoustic monitoring through the PC soundcard using the virtual bat detector mode of the Avisoft-RECORDER software (heterodyning or aliasing technique).
  • Very rugged full metal housing suited for rough field use.
  • Optional GPS data logging by attaching an USB or Bluetooth GPS receiver to the PC.
