Bats use echo location, similar to sonar, for locating food and navigating through the darkness.
This sound is a frequency so high people cannot hear it as bats fly around searching for food, communicating and going about their nightime business. But now you are able to hear everything they transmit. Our Bat Detector changes the frequency of sound being received a range which we can hear. It works by first reciving the sound through the small tranducer located on top. The sound then goes through the device, which is just bigger than a pack of cigarettes, where it is changed and then sent to a small speaker.
