Anabat Express Passive Bat Detector

D1000X Ultrasound Detector

The D1000X is a professional ultrasound detector, based on the latest technology. The detector has heterodyne, frequency division and time expansion systems and also a built-in 16-bit recording system using a Compact Flash card as storage medium. It is equipped with our well-known, high-quality capacitance microphone which has been further improved to give lower noise, wider dynamic range and lower distortion.

The D1000X has a built-in “recorder”, relieving the user from the hassle of operating a separate recording device or laptop with connecting cables. It can be configured to work in a variety of operating modes, but thanks to the use of “Profiles”, switching between different modes is made instantly. Each profile contains all the selectable settings such as sampling rate, triggering mode, time expansion factor and LED intensity and can be prepared in advance and saved in the detector.

At any time, either the direct ultrasonic signal, the heterodyne signal or the frequency division signal can be recorded onto the CF-card. Spoken comments can be recorded by speaking into the microphone while recording in the direct mode, or in a special comment recording mode (at a lower sampling rate). The recording time is limited only by the available space on the CF-card. Upon completion of a recording in the direct mode, the signal will be automatically replayed in time expanded form, if this function is enabled. Time expansion factors from 1 (original speed) to 30 can be chosen. The recordings can be made by manually starting and stopping the recording or through level-activated (and optional frequency selective) triggering. In the latter case, the detector can be set up for unattended capture of calls. Pre- and post-triggering modes with a variety of different settings can be used.

The wav sound files on the CF-card are stamped with date and time and can be read directly on a PC, using a standard CF-card reader. The D1000X also has a serial GPS input, making it possible to save GPS position data in the files.

D500X Ultrasound Detector/Recorder Mk I

The D500X is an ultrasound recording unit intended for long-term, unattended recording of bat calls. In contrast to time expansion bat detectors, the D500X records full-spectrum ultrasound in real time with virtually no gaps between recordings. The recorder is equipped with four slots for CF cards, which typically makes it possible to leave the unit in the field for more than a month. The triggering system allows the device to automatically start recording as a sound is detected.

D230 Ultrasound Detector

A combined heterodyne and frequency division 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 frequency division signal on the right channel. When the built-in speaker is used, a switch is used to select the heterodyne or frequency division signal.
