As well as the testing and comparison of the 3 microphones which are currently available, from Titley Scientific. These optional Mics allow additional, significant customization of your AnaBat Recording set-ups.
Owners of either The Anabat Swift, or The Anabat Express bat recorders, should be aware of the 3 Microphones currently available, from Titley Scientific.
What follows below, are just some of my findings:
1. The Anabat Omnidirectional Ultrasonic Microphone - US-0 V3
While doing some experimental tests, using The Bat Chirp II (artificial bat, made by Tony Messina); I was able to get (mechanical-looking) sonograms. I'm sharing these here, mainly as a "curiosity".
2. Anabat Directional Ultrasonic Microphone US–D V1
This was at a distance of 50 feet.
Here is just a small section of the sonogram, as recorded by "Mic #2": US-D V1
Until then, Happy bat detecting!
