Echo Meter Touch Bat Detector
Each of the 45 bat species in North America has a unique ultrasonic echolocation call, none of which we can hear. The Echo Meter Touch Bat Detector lets you not only hear these calls but identify them, as well. It plugs into your device's Lightning or MicroUSB port, using a specialized microphone to capture the sounds, and a companion app to turn them into something our human ears can understand.
