Oops, I scrolled right past that, sorry.
That looks like a great setup, maybe it's time to replace my two PACT Model 1's.
My first PACT is a "Pre-Model 1" from about 25 years ago, and uses a sealed lead-acid battery. It has no provision for diffusers over the skyscreens, and is a REAL PITA to get to register unless light conditions are ideal. The second one has a different skyscreen design with a "wide angle lens" mounted over the eye and diffusers mounted over them, and works much better. I also bought the optional infra-red thermal printer for it when I bought it, but there are still a lot of times when it misses a shot or several.
