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.
- Compatible with Myotisoft Transect

We have a Pettersson D240X, but it is picking up lots of road noise, I am trying to record bats on rocky cliffs next to a busy road. For noisy roadways, do we need another full spectrum detector?
The D240x does have a gain setting and trigger level setting, but it really was made for manual recording. If you are doing 1 night surveys then a Windows 10 device (such as a Surface Pro 4) running SonoBatLIVE https://batmanagement.com/products/sonobatlive connected to the Pettersson M500 microphone https://batmanagement.com/collections/pettersson-collection/products/pettersson-m500-microphone A huge advantage of this system is that it records -only- bat calls for the most part, thanks to a sophisticated noise rejection program. The second advantage is that if some care is done at the start of the session entering a field note and filename start, there is virtually no post processing that needs done and you can go straight to manually reviewing the bat calls of special interest. A disadvantage of this system is that while we are working on a passive solution, at the moment the only available solution runs of the Windows tablet, so you have to power it. If you need to leave the detector for a week or two at a time, the Pettersson D500x would be a good choice. It’s noise rejection system can be set to minimize the number of noise files but will not be as sophisticated as the SonoBatLIVE; so it will still record some noise files that will need removed using automated software such as the SonoBat Data Wizard during post processing. However, the D500x records constantly, unlike the D240x which must suspend for ~17 seconds, etc. so bats would not be “missed” like they potentially might be with the D240 in auto mode. The D500x can also be used manually if that’s what you're used to doing with the D240x, except there is no downtime between recordings and no realistic limit to file length.

Are you able to hook up the D240x with a windows 10 device to run sonobat Live? if so what is required
Hi- SonoBatLIVE works with digital USB powered microphones such as the Pettersson M500 and Binary Acoustic Technology MiniMic and AR-series of microphones. Possibly other USB microphones will work, at least in the near future. Because the D240x is not USB it may not be used.
