Jim,that is freaking awesome!!! As far as measurements go the hollow rangefinders that I and I'm sure many others have is from "bobamaker" since he was the only one that recently offered them....and I just measured the interior as it came,with a width clearance of 1". If the right angle sequencing pins made up the 1/8" difference then I'd really like it if they were upright since there is still room with that respect.
Again,it's coming along rediculously AWESOME!! :cheers Thanks so much for picking up the ball and running with it on this for us.
I can't wait to see the final product with battery and a tilt switch :love
