aimed at recording bats. As well as its very compact size, its main feature is that the user can check battery and SD card status and configure it using an iOS or
Android mobile device via bluetooth. It can run for 240 hours from four AA batteries. There are some preset configurations such as run continuously, run for two hours at dawn and dusk, run for five minutes every hour, etc. Users can also create their own custom schedules and then upload these onto the recorder. The recorder comes with one microphone but there is space for a second (needs to be bought separately).
