I get some ppl don't like wearing watches (like shotscope). But I'll give my experience bc I've been very pleased with the shotscope v3 and it was my favorite golf purchase in the last few years. Best thing off the bat is price vs arccos, much rather pay onetime 240 versus a yearly subscription. Its small and I don't notice it while swinging. I barely interact with it during the round as it's just pick the club and swing (no remembering tap function). It's been accurate, you will usually have to make some minor edits to your round after but never takes me more than 5 min (plus I honestly like to review my round). However biggest compliment I will give is to the shotscope support. They honestly take feedback from users and introduce them into the app. I have submitted two suggestions and within a few weeks the additions were added (simple stuff like describing their statistics better). Anyone who has used shotscope over the last year can see how much the app has improved.
