You’re ready to tee off on the 14th hole at Pebble Beach, but before you step into the tee box, you take a look at your watch — a big taboo. But not if you’re wearing a Suunto G9, with a 12-channel GPS system that accurately calculates pin distance and warns of sand traps and water hazards. It also records the distance you hit the ball and becomes a virtual caddy, able to recommend club selections after “playing” only a couple of rounds with you. Sweet. $725.
