Product information
This is a simple to use heterodyne type bat detector which is used to translate the inaudible high-pitched bat chirps into an audible sound. Listening to the ultrasonic echo-locating bat chirps is fascinating for identifying the species, locating and tracking bats.
Bats use inaudible ultrasonic sounds like a sophisticated radar system to avoid obstacles and locate prey.
The bat4 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 15 to 130khz.
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.
The detector uses the Heterodyne principle.
Ultrasound is picked up, amplified, and mixed in a special way with another signal generated in the bat detector.
This design is used by amateurs and professionals alike and is earning a good reputation for performance, quality and reliability.
The detector can also be used for listening to ultrasound from Rats, Crickets, etc
It is simple to use - even by absolute beginners.
British Bat Identification Field Guide also available.
