I thought arccos had a better set up with stats layout ect, but I didn't like the putting feature or the subscription fee, shot scope is pretty good the putting is probably the better of the systems when used correctly you need to give the watch time to catch up if your too quick it will give false gps readings like ball position, I prefer the manual putt as I like to practice my stroke when waiting, as a stand alone GPS watch it's very accurate too, basically the putting works in 2 ways auto or manual, auto works like any other club the watch reads the tag and pins the GPS position on the course but will change from yardage to the putting side when you are 5/10 yards from the green, once you sink the putt press pin on the watch at the pin to set the pin position, watch then goes to the next hole, manual, once your at your ball you would need to press + on the watch to mark were the ball would be for every putt you have once sunk press pin, same as auto mode, quite simple.
