I've finished 5 rounds with the V5 watch. I previously used the Arcoss which worked very well, but when the batteries wore out so I would have to buy new ones and fork over another $80 for membership I was done.
So far, the V5 is easier to use and works just as good picking up shots and you can glance at the watch and see it picked up the shot. I think it handle putts on the green much better also.
Glad I switched (and so`s my wallet)!
