I too am having a falling out with Arccos. Subscription cost is high and having to replace sensors at a cost is a double gut punch.
I would ask what you want to use the watch for away from the course. I love Garmin watches and have used them for years in running and triathlon and the golf features are awesome. But away from the course they lack a lot of the “smart” capabilities of an Apple Watch. I would consider a new Apple Watch and look at apps that might come close, I think The Grint is trying to add a lot to the watch app. Just my two cents.
