prey and navigate through their environment by analyzing the
echoes of their ultrasonic calls. These high frequency calls
- typically between 25kHz to 125kHz - are inaudible to
humans, as they are beyond the normal range of human hearing
- about 20kHz maximum.

Equipment used by biologists for bat bio-acoustics research
is expensive, rather bulky, and typically requires larger batteries
for extended field use. This pocket-sized detector, with its
low power circuitry, allows you can determine presence / absence,
or perform censusing and population dynamics studies using a
hand-held detector that will last for weeks with a single 9 volt
battery. This low-cost detector is a perfect educational tool,
as several can be purchased for a high detector-to-student ratio.
