BRB - Wow. Now that is a sweet setup! Congratulations. Gamechanger for sure. You'll be able to hear a mouse walk at 100 yards. Do you know what SONY headphone model you got? When you get familiar with using it, it would be great to hear someo audio files of things moving about in the night.
I've been eyeballing that exact parabolic dish and mic. How do you plan on carrying the dish? Will you attach it outside to the front of your backpack, the top of it, inside the pack? If outside, how will you lash it down to your backpack--paracord, thin bungee cord, other?
You've got a video camera, a thermal imager, and now the parabolic dish setup. You are loaded for bear!! Mr. Sasquatch, meet your match--our own Mr. BRB!!
My best sasquatching spots all involve a remote pond. I can imagine how that parabolic dish would be able to pickup any sound of something across the pond walking as the sound carries well over water and the slightest noice would be detected, heard, and recorded with that setup.
Way to go BRB and thanks for sharing.
