Compact, lightweight, single-channel bat detector and recorder.
Developed specifically for bat research, the SM4BAT recorders combine innovative design with a new low-power processor and easy-to-use scheduling features. Available in full-spectrum and zero-crossing models, the SM4BAT will make bat research simpler, faster, less costly and more reliable. The SM4BAT FS creates high-quality, full-spectrum recordings that can be easily converted to zero-crossing recordings using free Kaleidoscope conversion software. The SM4BAT ZC creates zero-crossing files that optimize power and data storage.
Small, secure and weatherproof.
Designed around the footprint of 4 D-size batteries and made of rugged polycarbonate, the SM4BAT is less than half the weight and size of the SM3BAT. The integrated mounting bracket and weatherproof security cover keep the unit safe and dry in the most punishing environments.
Longest deployment times available.
The new, low-power microprocessor, combined with 4 D-size batteries, enable the longest deployment times of any other bat recorder available. The SM4BAT FS has a recording run time of 300 to 500 hours depending on bat activity and other factors. The SM4BAT ZC run time is even longer. See Specifications for details.
Easy to program.
To get you started quickly, the SM4BAT features a brand new, easy-to-use, Quick Start menu and Scheduler. Use built-in schedules, or customize them for your specific recording needs.
Available GPS accessory to set clock and location.
When deploying multiple recorders, use a single GPS accessory to automatically set the date, time and location settings of all recorders. The GPS accessory can also be attached to log the recording locations and path for mobile transects.
