The 'Echo Meter Touch 2' is a new Apple device attachment from Wildlife Acoustics that can be used to detect, record and identify sounds made by bats.
The device takes the form of a block-like add-on that plugs directly into the Lightning port of an iPhone or iPad. When this device is used alongside the Echo Meter app, it becomes a smart detection tool for a variety of bat sounds. The device is able to pick up on sounds and displays them on-screen as spectrograms, as well as determines which type of bat the sounds most likely came from.
Knowing that the device has appeal for both bat enthusiasts and professionals, the attachment is available in two versions.
