When it comes to golf there seems to be a never-ending stream of gadgets. Some of these are helpful, others, well, not so much. Highest on the list of helpful gadgets are GPS units. A good golf GPS unit can do many things that take some of the guessing out of golf.
Most notably: guessing distance.
When club selection is so often dependent on how far away you are from the hole, you need something that will take the guessing out of measuring distances. This is where a good GPS unit comes in handy.
