Bat detector

Bat detector
The detector makes sounds at frequencies of 10-300 kHz audible to human beings. The conversion is ca ried out either by a superheterodyne circuit or a frequency divider. Although it enables listening to bats, and a number of other mammals, as well as insects, the detector isparticularly useful for testing ultrasonic alarm equipment.
