Automatic bat detector

The automatic frequency tuning of the BATSCANNER offers many advantages:

  • Immediate display of the main frequency, even with only a brief flyby. This also helps to get a first estimation of the species.
  • Miss no bat, just because the wrong frequency is tuned.
  • No tedious search for the optimal setting, which is especially helpful in the dark.
Excellent audio performance

The heterodyne converter is digitally driven. This gives the BATSCANNER a clear sound and only minimal noise. The built-in loudspeaker has been optimized to avoid feedback loops and connected to a headset, one can concentrate even better on the bat calls.

Small and handy

The BATSCANNER sits comfortably in the hand, is leightweight and not too big to take it with you everywhere you go. Thus one is always prepared. Whether on the evening walk or the next bat excursion, the BATSCANNER is the ideal companion.

Noise reduction

Crickets and noise from walking are an annoing problem when observing with bat detectors. The BATSCANNER minimizes this problem by a special handling of lower frequencies. Moreover, with only on button press the frequency is reset so the noise is gone. Nevertheless you will not miss any noctule.
