More than a few, lol. Score at the end of my round, pre-editing, was 64, and after editing it was 82. Plus there were also a bunch of tee shots that were automatically added, so I'm guessing I missed between 25-30 tags total. I'm sure I'll get used to it though once I am unaccustomed to the automatic tagging watch.
I'm also so used to the watch that I kept checking my wrist out of habit.
I like the device a lot. My only minor complaints are:
I didn't like taking it on/off the clip on my belt to use as a distance measuring device (at least in winter when my layers cover my belt, so I am going to see about attaching the clip to my bag or push cart somehow.
The vibration is subtle, but once I got a sense of the frequency/duration of it I could tell when the tag was successful.
It is small, but I only fumbled and dropped it once.
I stand just far enough away from the net that I’m not going to hit the frame in the follow through with the club.
The ball shouldn’t ricochet back towards you with that net. The bigger problem is the wind likes to knock it down.
