Golf gps units have come a long way very fast. Remember when they first came out and were not legal for competition play. Thankfully the USGA saw the light and made them legal, after all it just leveled the playing field so the average golfer could have a caddie also.
The first gps units were hard to operate, had bad graphics, were not very accurate and only told you how far to the green. But now these golf GPS units have gotten hugely better in all areas. The graphics are life like, you have measurements to and over the bunkers and the ponds. And you can access the information before the group behind you hits into you.
These are a great addition to the golf equipment you already have and can lower that handicap score just by keeping you out of trouble, and save some of your golf balls from swimming.
Come back later for more GPS units 101 and the rest of the story.
