I have had two different Shot Scope watches. But when an Apple Watch became a medically-necessary accessory AND I was ‘grandfathered’ (read: NO monthly fees!) I sold my SC watches. For all the things that Arccos can do, they still don’t measure the intermediate distances quickly/easily. Their comments: “that’s a great idea!” I read about the H4 and ordered one - which fell out of the magnetic clip on my first round (between 15-17). SC graciously gave me a nice discount (not free) to replace it. So, I ordered another H4 from SC, and found a nice, small zippered pouch at ‘Bezos mart’ with a caribener, that clips SECURELY to a belt loop. NOW, when I have a water hazard or bunker in my way - I know the distances to and beyond it - without screwing around with a rangefinder. Want to know ‘the rest of the story’ with Arccos? Get an H4!
