No problem, they can just issue a Bushnell, or better yet, Sky Caddy, to every player.
Middle of green distances would be pretty useless at Rustic Canyon, but front of green plus pin sheet would be more helpful. Slower of course but helpful.
That reminds me of Steve Pieracci's math at the Palms, or was it Plantation, at KPV. Added the yardage to front of green to distance off the pin sheet, and somehow came up with 187 instead of 177. Man that was a good looking shot, a laser right at the flag, until it disappeared over the green on the fly! After that we checked each other's math but it didn't help, we got waxed!
