I'm interested in the purchase due to the "deal" with the MAS. I did a search for the ProM 75mm and still came away with some questions I need clarified before I jump in. Didn't find any good information on the MAS's.
It seems there are two MAS made specificaly for the Contour a 75mm metal one and an 80mm plastic one. I'm wondering how we got a plastic 75mm one? Is this just a 'generic' MAS that we can use on our contours? If so does this need to be calibrated like the metal one giving all pertinent info, mods, filters etc. I guess I could of made this simple and said give me more info on the MAS?
