STROKE SAVER

RadarGolf golf ball finder

For every golfer tired of searching for errant shots -- and the inevitable penalty stroke when you can't find your ball -- there's now a high-tech way to track them down. RadarGolf's golf balls are embedded with a chip that emits a radio signal to a handheld device, which then directs golfers to their ball. (The ball conforms to USGA specs and is comparable to Callaway's HX Red.) Cost: $200 for the handheld scanner and the first dozen balls. Replacements are $40 a dozen, but it should be many rounds before you need to reorder (888 723-2701, radargolf.com).
