Not sure what your point is. It's hard to hear bats. Badgers can't
see red light. Our eyesight is as good in the dark as that of a cat.
Various instruments can detect what none of us, or any other animal,
can detect. Also, we've a built-in bullsht detector, and the reason
to conduct valid tests to see what works, or doesn't. Dowsing doesn't.
