Bats use inaudible ultrasonic ‘sounds’ like a sophisticated radar system to avoid obstacles and locate prey. The bat5 detector takes the inaudible high frequency ultrasound and converts it to frequencies between 100Hz and 12kHz which are in the range of human hearing. The detector can be tuned to receive a range of frequencies from 10 to 130 kHz. The sounds are heard via a built in waterproof loudspeaker, and there is a socket to connect standard stereo ‘walkman type’ headphones. A separate constant ‘low level’ output is provided for connection to a tape recorder or PC sound card.
