HETERODYNE BAT DETECTOR

This sensitive heterodyne bat detector is ideal for the amateur enthusiast looking to explore the hidden world of bats.

This device will allow you to listen to bat ultrasonic sounds while bats are flying and tune in to the different frequencies from the various bat species by way of an adjustable frequency dial from ≈20kHz to about ≈120 kHz..

Other than bat ultrasounds this device will enable you to listen to other animals, insects, splashing water, pins dropping and rattling keys producing ultrasounds.
