Based on the powerful SM2 Recorder Platform, the SM2 Terrestrial Acoustic Package includes two SMX-II weather resistant acoustic microphones. Using the four alkaline "D" size internal batteries, the SM2 can record up to 240 hours spread out through weeks or months at a time. The collected data can then be analyzed with our Song Scope software.

Based on the powerful SM2 Recorder Platform, the SM2 Night Flight Call Package includes a special SMX-NFC weatherproof microphone designed especially for recording distant night flight calls in the sky while attenuating sounds from at and below the horizon such as insects and amphibians. The SMX-NFC has a microphone capsule mounted near the surface of a flat horizontal plate creating a pressure zone for sounds originating from above the plate. The design delivers flat frequency response up to 11kHz and 3-6dB signal gain with a beam angle of 125 degrees. For best results, the SMX-NFC would be mounted on a rooftop or high on a pole to keep it away from crickets and amphibians at ground level.
