Ouch, yeah NM is so high altitude. I'd guess it was tough to maintain any golf course.
There were some spots just outside of Los Alamos, where I played "mental golf" My wife and daughter both looked at me and in unison said, "It's not a golf course."
I use a GoPro Hero 4 silver and it has been more than fine for recording video and working with my Evolvr coach. You can get one for pretty cheap too. Using 1080p mine goes up to 60 fps, but the Hero 4 black can go up to 120 fps at 1080p I believe. Models newer than the 4 would definitely work as well but obviously cost more.
I like the small form factor of the GoPro, I currently just use a small "Gorillapod" that I secure to the top of my golf bag and that seems to give me the perfect height to film my swings. When I'm not filming, the camera and Gorillapod fit in the side pocket of my golf bag no problem.
Plus I use the GoPro in my drone and attached to the boat while fishing.
I disagree that my proposal would require that. Since it modifies the rule by defining a drop point closer to origin than where the ball is thought to have actually ended up, it should be workable just like the ball unplayable rule, just taking a one stroke penalty for the luxury of being allowed to drop and not playing the ball as lies. Stroke and distance would still be in the rule if no such drop point was identifiable.
