iPhone of golf GPS technology," what then would you call this? Savant GPS has just come clean with what's likely to be the most sophisticated GPS rangefinder to date. The simply-titled OnPar measures in at 4.17- x 2.8- x 0.63-inches and features full touchscreen (3.5-inch) operation. It's also claiming to be the planet's first "GPS rangefinder with a dynamic hole layout display and GPS positioning that provides instant distances to anywhere and remaining distance to the green, personalized club averages, and simple score and shot tracking." The unit is designed to hold up to 300 golf courses with no membership fees or course map fees, and it'll be available for the taking (er, purchasing, we should say) early next month for an undisclosed price.
