Well, first season of being a caddie was awesome, and the start of season 2 is approaching quickly!
I think I over-analyzed things in the beginning, the members of the course definitely know their way around the course and rarely (if at all) ask course management questions. Most of what I do is watch where the ball goes, fix divots/rake bunkers, clean clubs/ball, and hold the flagstick while on the putting green.
About half the people I caddie for have distance measuring devices (laser rangefinders), and they DO let us use the rangefinders to get distances for them. The other half don't have measuring devices and they seem to be fine with us giving them yardages based on us walking off distances from the sprinkler heads for them. There was only one time that I caddied where a guy didn't have a measuring device & seemed upset because I didn't have one for him. There was one hole where I gave him yardage and he overshot that distance by a mile & ended up out of bounds. (In my defense, the yardage I gave him was correct ... but he neglected to account for the SEVERELY downhill shot & had way too much club for that shot)
I know a couple of the older & more experienced caddies bring their own rangefinders, so I'm wondering if I should bring mine along as well. They aren't cheap so by me using it to caddie, I'm only shortening the life of the device before it craps out on me. Would a caddie make more money by bringing our own rangefinder? For the golfers that already have one, I'd be carrying extra weight (we already have to carry alot of items) for the whole round. But for the golfers that don't have measuring devices, would they be inclined to pay more for a caddie with their own rangefinder?
