Lots of negative on the forum, so want to bring some positivity. As a pretty serious golfer/golf nerd I was a bit skeptical with how good this can be. Since new software update it has exceeded my expectations and that of all my golfing friends. Prior software I think the estimated spin seemed to be biggest issue where it seemed low so consistently about a half to a club long throughout the bag, but 3.70 has my yardages and shot shapes seemingly perfect. I even hit on a TrackMan Sim to test against and carry distances consistently within 2 yards with club and ball speeds virtually identical. Keep up the good work with updates!
