I am starting to work with some possible applications of a device, and I
want to test it to record bats. So I wanted to ask if anyone can give me
some pointers in the right direction.

I have been unable to find a mic for ultrasonics on the internet, just a
few sensors that will require extra electronics to interface it with the
sound card. Maybe I'm thinking of it the wrong way? Maybe I need to
search using a particular name?

What I need is a mic to record up to 80 kHz. A flat response would be
desirable, but at this stage, I'll settle for a reasonable response up
to 80 kHz.

All ideas and suggestions will be appreciated.
