I’ve just switched back to Game Golf after using Arccos for 12 months, you do have to pay the fee, which I think was £89.99, but that wasn’t the issue.
My issue was the amount of editing I was doing after the round, sometimes it was perfect, then next time out I’d get to random holes (happened on different holes over different rounds) and all the remaining shots in the round were recorded on one hole! So you get to review your round for example and find the 11th has you playing it in over 40 shots and nothing recorded for holes 12-18.
Hopefully Game Golf is back for good, but after just 3 rounds I’ve missed no shots and the GPS is no worse or better than Arccos, but I’m not spending time editing post round.
I know it’s not for everyone, but I find the tagging no issue and it’s part of my PSR.
