I'm guessing here, but does it shift the inaudible bat sonic emissions
down into human hearing range? Maybe a parabolic dish with headphones?
Or does it use radio wave reflections to track the target? Possibly,
it detects their infrared signature and plots it on a miniature cathode
ray tube in an eye-piece? Or maybe resonance in the bat wings it found
through laser refraction?
In any case, I hope you blow those little #@%$%#$s out of the sky!
