So there are a lot of threads about Approach S70 not detecting shots.
(My TL;DR : it used to work fine (first three months' of ownership). Last couple of rounds, tee-shots not picked up, fairway shots not picked up. I haven't changed any settings. I haven't changed how watch sat on my wrist. I haven't changed my swing. So why does it just stop working.
Anyway looking at the discussion, it seems that if auto-detection doesn't work, then you should use "measure shot". But I just don't understand that. I am in a round. I don't know that the first (say, tee-) shot wasn't detected until I play the next (second) shot. Yes, I may not have had a reminder to select club, but I don't always notice that. When I have played the 2nd shot, it is too late to measure the first shot.
Better still would be for Garmin to fix the problem, but given that this seems a common issue for a couple of years no by looking at this forum, what is the best work-around
A related question: how do you know from looking at the watch immediately after the tee-shot that the shot has been detected. I know that if I walk, then a detected shot will trigger the counting of the length of that shot, but that takes me walking 5 or 10 yards and so how do I do that whilst still on the tee-box, so that - assuming I can remember - I can switch on "measure shot"?
