I've been lent an old batbox III detector. I've not got any instructions so I'm not sure whether I'm using it right. Anyway, I had my moth trap on last night and I could see a bat flying around, chasing moths. Every time it flew over I could hear a series of clicks.
What I don't understand is that I could hear the clicks through a whole range of frequencies from about 22Khz up to about 45khz. The volume seemed to be loudest at 45. How do I interpret this?!
