Golfers crave knowledge. They want to know it all, whether it's learning a new tweak for their swing or understanding the layout of a course they're getting ready to play. For the latter, the Garmin Approach S70 has every feature a golfer could ever want. It builds on the legacy of the beloved Garmin Approach S62 with a new, more vibrant AMOLED display, improved course maps, and number of other tweaks, meaning this watch could become the most powerful tool in a golfer's arsenal.
