The Pettersson D240X is a combined heterodyne and time expansion detector. It allows you to convert ultrasonic bat calls into distinctive audible sounds, whilst capturing fragments of time that contain useful call information.
Key Features:
- Easily adjusted with wheel frequency and volume controls on the side
- Easy-to-use functions like a back-lit screen with a large digit display, which shows the frequency in the heterodyne mode.
- Compatible with stereo headphones: hear the heterodyne signal on the left channel and the time expansion signal on the right channel
- Built-in speaker - switch between the heterodyne or time expansion signal
- Compatible with digital recorders such as the R-05 Edirol or Tascam DR-40 enabling you to record the time expanded calls for analysis on a PC. If the recorder has a "voice-activated" recording mode, the detector can be left in the field for unattended recording of bat calls
