Didn't Rodney whip this out in "Caddyshack"? No, but this digital slide-in device measures swing path, impact position, face angle, swing tempo and stroke speed. By turning the club left or right, you control menus on the LCD screen. Includes a metronome tone, grip sensor and digital data storage. Distributed in the U.S. by Adams Golf.$1,000 / dixxgolf.com
Nokia N93 Golf edition

Comes loaded with playing tips and tour-pro swings. Available in the U.S. this summer.$1,100 (estimate) / nokia.com
Suunto G6
A stylish scorekeeping watch (four games to choose from) that logs performance stats, like fairways and greens hit and putting average. The G6 also collects swing data -- tempo, rhythm, backswing length and speed -- with every swing you take. Download the data onto a computer and use Suunto software to analyze stats and track progress.$449 / suuntosports.com
Nintendo Wii
Send the kids to bed early. Nintendo's newest game system offers Wii Sports, where you swing a remote control like a golf club, and the motion is mimicked by a caricature on your TV screen. Swing too hard, or yank it left or right, and you're in virtual bogeyland. A new golf game, Tiger Woods PGA Tour 07, is due out this month.$250 / nintendo.com
Bagboy Navigator
Nice wheels. No kidding, these high-tech aluminum rims with steel ball bearings keep the going smooth, as do twin 140-watt motors powered by a 34-amp, dry-cell battery. An on-board compass controls direction, even on sidehills. Adjustable to fit every bag and every golfer, and folds for easy transport in the trunk.$1,500 / bagboycompany.com
Skycaddie SG4
Range finders are so 2006 compared to the SG4, which draws from a downloadable database of more than 11,000 precision-mapped courses. It points out up to 40 targets or trouble spots per hole (as many as three at a time) and shows the full depth and shape of the green from any angle. Doesn't require aiming.$350 / skygolfgps.com
