I can see this is a fairly common issue. I have had my S70 for 2+ months and it has been a very frustrating issue for a $700 watch. Today 8 drives (driver & 3 wood) did not record. And my swing speed is NOT slow. Tried practice swings first, after, hoping it detected movement but NOTHING. Once off the tee it reacts fairly well until around the green, but after reading other forum member's comments I'll try using the Measure Shot feature. Also just downloaded the latest update and see how that goes, but if the watch needs to detect the striking of the ball I'm not too optimistic.
Any other suggestions are GREATLY appreciated.
