Ahh, Mike....I see you are (were) looking into Ultrasound.
Step away from the Buy it Now button
You can get an ultrasonic transducer for a few bucks online.....either new or used. If you had an old dynamic mic, you could replace the electret mic with the transducer.
Link to mouser electronics:
You could build one from schematics:

I built one from a kit a couple of years back. It works just peachy-keen. I can hear bats clicking away. I can hear mice - running water - rubbing your fingers together - etc.
Here's a pic of mine..............
