Petterson D240x

The Pettersson D240x is (just like the Pettersson D100 and the Batbox III D) a heterodyne bat detector. However, this detector also offers:

• Sound recording (max. 3,4 seconds)
• After the sound is recorded it is possible to playback it in heterodyne while simultaneously altering the frequency at which you are listening. A sound that cannot be directly identified can thereby be repeatedly replayed and assessed.
• Delayed (time-expansion) playback of the recorded sound (the sound is slowed 10x, thereby also lowering the frequency 10x).

The ideal bat detector for anyone who works with bat detectors professionally.
