The ultrasonic packages are based on the powerful SM2 Recorder Platform. Stereo 192kHz Option
The stereo 192kHz option includes a two-channel 192kHz 16-bit sample rate card and one SMX-US weatherproof ultrasonic microphone. With two channels, it's like having two bat detectors in one. A second ultrasonic microphone extended on a cable can be used to monitor bats up to 100 meters away. For example, one microphone could be mounted at nacelle height and another near ground level to meet the requirements of many wind farm pre-construction surveys. Alternatively, the second channel could also be used with a conventional SMX-II acoustic microphone to record birds, frogs, and other wildlife either simultaneously or at different scheduled times with bat monitoring. Bat echolocation calls up to 96kHz can be recorded, sufficient for monitoring nearly all species present in North America. For details and specifications, please refer to the Song Meter SM2BAT 192kHz Stereo Ultrasonic Recorder. supplement to the Song Meter SM2 User Manual.
Mono 384kHz Option
The mono 384kHz option includes a one-channel 384kHz 16-bit sample rate card and one SMX-US weather resistant ultrasonic microphone for recording bats at higher frequencies. The second channel can still be used with a conventional SMX-II acoustic microphone to record birds, frogs, and other wildlife at different scheduled times, but not simultaneously with ultrasonic monitoring.

Original full-spectrum recordings preserve amplitude and harmonic details of original signal. Compatible with Sonobat
Output triggers can be split into individual .wav files, scrubbed to separate files likely containing bat echolocation calls from noise, and digitally compensated for microphone frequency response to work with Sonobat. Compatible with Legacy Zero Crossing Analysis
Alternatively, output can be converted to zero crossing files compatible with legacy zero crossing analysis tools, while preserving the original full-spectrum recordings for later analysis. |
"The calls collected were of very good quality and the detector worked precisely as programmed. Very good coverage. A separate comparison test was done side-by-side with the Petterson 240X... The result was 6 bat calls of high quality by the 240X and 112 calls by the SM2." More... Joel Tigner, Batworks, LLC, South Dakota, USA "I field tested the SM2BAT this winter, and overall I was impressed with the unit... Here is my top 10 list for why I like this detector for passive monitoring:" More... Cori Lausen, Birchdale Ecological, British Columbia, Canada CompetitionThe above testimonials from leading bat biologists confirm that the SM2BAT solution detects more bats at a fraction of the price. See our competition feature chart to find out more about the SM2BAT's superior capabilities to competitors like the Anabat SD2, Pettersson 500X and Binary Acoustics FR125/AR125.
