Visited my club for the first time in a month on Labor Day for a round with my wife. The first thing I noticed in the cart was they had retrofitted it with a USB charger. I ran back into the shop to let the pro know I thought that was a great addition and a game changer for those with GPS / phones.
One subtle difference maker with my Bushnell is being able to tell a playing partner (hacker) the yardage to clear a hazard on an approach. It seems to give them confidence to be able to cover the distance with a normal swing instead of over swinging with the yardage to the middle of the green in their mind. The time saved from looking for their water ball after 'swinging for the fence' is a nice benefit.
I think the new tech in driver's is important too. I know I'm keeping the ball in play off the tee much more than I did years ago and has been a tremendous help in consistency.
