NDAR15MAN,
I don't have an answer but I will tell you what Tom Austin told me. I have zero experience going hands-free. When the Hogster came out, I was determined to find a way to run it hands-free. I thought what a great option, a small thermal that can be used hands-free, as a handheld scanner, and a weapon's sight.
After figuring out what I thought I needed to put it all together, I asked Tom will this work. His answer was, yes it should all work together. However, just because it would physically work, doesn't mean you should do it. He said due to the weight of the Hogster, and the counter-weight required, it would feel like your head was being squeezed in a vice. After he told me this, I decided to drop the project.
My experience may not apply to your situation, but it may. Most compact thermals could somehow be MacGyver'd into a solution whether it should be or not.
