D240x Ultrasound Detector

D240x Ultrasound Detector

10,500 kr excl VAT

Very popular heterodyne and time expansion detector with backlit, large digit, accurate digital display, showing the tuned frequency in the heterodyne mode. The frequency and volume controls are on the side of the case, making it easy to adjust. Using stereo headphones, the heterodyne signal is heard on the left channel and the time expansion signal on the right channel. When the built-in speaker is used, a switch is used to select the heterodyne or time expansion signal.

A digital recorder can be connected to the D240X to record the time expanded calls for analysis on a PC. If the recorder has a “voice activated” recording mode, a fully automatic bat recording system is obtained, which can be left in the field for unattended recording of bat calls.
