About this product

PLEASE NOTE: the Song Meter Mini lithium-ion battery lid is no longer available. Instead, a dedicated lithium-ion version of the Song Meter Mini 2 Acoustic can be purchased with greatly increased battery life. 

The Song Meter Mini 2 is a smaller, more lightweight and affordable alternative to the Song Meter SM4 Acoustic Recorder, which provides the same high quality recordings. It builds on the technology of the original series with a redesigned hinged lid and significantly improved battery life for the AA model thanks to an increased capacity of 8 batteries. It also features a 1/4" tripod mount for easy field deployment using off-the-shelf products.

This is a simple, yet innovative device for recording birds, frogs and other species that communicate vocally. It is weatherproof, robust and is easily mountable using screws, rope or cables such as the Python Lock. The recorder comes complete with a field serviceable microphone for high-quality recordings and a second microphone (available separately) can be added for stereo recordings. 

The schedule, set-up and status of the recorder are operated via Bluetooth using an app that can be downloaded to your iOS or Android phone/tablet. There is also an option to set the location and time zone of your Song Meter Mini 2 using the GPS from your mobile phone. The app is simple to use and allows you to manage multiple recorders at once. Checking the status of your recorder can also be done using the LEDs on the unit itself.
Power is supplied internally using 8x AA batteries which last for hundreds of hours and recordings are stored in 16-bit WAV format on an SD card. The SM Mini 2 Acoustic is compatible with Kaleidoscope Pro software to help analyse your recordings.

The starter bundle includes the detector, 8 x lithium AA batteries and a 64GB SD card. 

Please Note: The stub microphones of the SM4 are not compatible with this device
