Pettersson D240x

Heterodyne and Full Spectrum Time Expansion Bat Detector

The bat detectors from Pettersson Elektronik are high quality instruments, designed in close cooperation with leading bat workers for optimum performance in full spectrum recordings. As a testament to Pettersson's "done right the first time" philosophy, this is one of most longest-lived products in the Pettersson line introduced around 2003 and still holds it's value today.

Two detectors in one! Select between HET or TE audio technology at the flip of a switch. A backlit, digital display shows tuned HET frequency. This is used when actively monitoring bat activity so you can hear in real time when the detector is receiving a strong bat call.

Listen to the HET output in real-time for the ideal bat pass while the D240x simultaneously records the full spectrum (10-120 kHz) sound. When a suitable, desired bat has just passed by and the HET clicks are starting to fade, single-handedly stop the full spectrum recording with a button push on the back of the D240x. The D240x will continually replay the full spectrum (and now time expanded) call which can be off-loaded to a separate recording device such as the H2 Zoom or into a laptop running SonoBat or Batsound.

Flip the master output switch to TIMEEXP to listen to your newly recorded bat pass in 10x time expansion and the high quality tonal qualities that only full spectrum recordings can capture.

The D240x records up to 3.4 seconds at a time, then a decision must me made to either save the recording or wait for another bat pass. While best used for active recording, it can be configured to operate passively for up to one full night. Depending on settings, there will either be a ~18 or ~35 second delay between recordings while the previous file is saved to an external recorder or app.
