Leupold GX-3 Rangefinder $400, golf.leupold.com The GX-3 may look like your dad's rangefinder, but it's fully loaded from eyepiece to lens with an assortment of pin-seeking goodies. Leupold's compact laser can accurately pinpoint a target as far away as 800 yards (in case you're playing one of those pesky par 8s), and its fog mode can cut through weather that might disrupt satellite GPS systems. The GX-3 also features a "scan mode" that lets you take multiple readings without resetting, and, most importantly, it's tournament legal, so you won't ever have to leave it at home.

Leupold GX-3 Rangefinder $500, bushnellgolf.com While the debate continues to rage over whether laser rangefinders or digital GPS units offer golfers the best way to gauge distances, this product splits the difference. As the name suggests, Bushnell's hybrid is the first combination laser and GPS rangefinder to give golfers the best of both worlds. While the rangefinder can give you precise point-and-shoot distances, the GPS function (loaded with more than 16,000 courses) gives you distances to the front, center and back of the green. You can even use the "shot distance" mode to find out just how far your drive went.

Garmin Approach S1 Watch $250, garmin.com It may not have a phone, but Dick Tracy would appreciate Garmin's fully functioning sports watch, which also gets you from tee to green. The waterproof S1 comes loaded with more than 15,000 North American courses, and it gives measurements to the front, center and back of the green. The large-print face also provides a running pedometer and distances on individual shots, and the alarm clock makes it the perfect gift for the guy in your foursome who's always late—or for Jim Furyk.
