Wildlife Acoustics Song Meter Mini Bat 2 AA Ultrasonic and Acoustic Recorder

Song Meter Mini Bat 2 (AA) Ultrasonic-Acoustic Recorder: Capture Nature's Essence in High Fidelity

The most versatile and compact wildlife recorder, designed for monitoring bats and acoustic biodiversity with unprecedented energy efficiency and total weather resistance.

The Song Meter Mini Bat 2 redefines wildlife monitoring by merging advanced ultrasonic capture with ease of use. This device allows you to record bats and other species vocalizing in the ultrasonic range for extended periods of up to 50 ten-hour nights. Thanks to its low-noise microphone, it can detect distant and subtle echolocations, while integrating smart-triggering technology that filters out "false triggers," ensuring every stored file provides high scientific and commercial value.

Beyond ultrasonic capabilities, this recorder offers exceptional flexibility. By adding an optional acoustic microphone, it transforms into a comprehensive tool for studying birds, amphibians, and land mammals. Its nature-inspired design allows for seamless integration into the field, reducing analysis time by delivering cleaner and more precise recordings—allowing researchers to focus on what truly matters: understanding ecosystems.
