Retired and play weekly.I tried Arccos years ago and was happy with it . Just got new clubs and tried it out.This new Gen 3 version is great. Its very easy to install. Just screw sensors into top of grips and tell caddie App what club you installed. I was really impressed by how accurately it tracked my shots. Its like having a caddy in your phone. Can't wait to use other features which will give me more information about my game and help me become a better golfer.
