3) camera needs repeatable positioning... cover the bottom of the camera with press-n-seal, mount camera to hat, then smoosh Mighty Putty or equivalent around the corners of the base of the camera.

A cross bar will take adjustment, but those will help aim vertically (and is actually most important... if I'm out of frame at all it's on the vertical axis). Will take some practice and testing to aim the horizontal bars on the reticle, and also to get used to it being...Continue Reading
