Officials at Leupold, the Beaverton, Ore., company that makes rifle scopes, binoculars and other sophisticated optical devices, say the release this past winter of its new GX-1i and GX-2i rangefinders, and the unveiling in April of a more economical, entry-level device called the PinCaddie, show that the company continues to make improvements in its golf product offerings. The GX-1i and GX-2i incorporate Leupold’s DNA (digitally enhanced accuracy) engines and advanced infrared lasers so the devices provide even faster measurements with accuracy displayed to the nearest half yard. They also utilize the company’s exclusive PinHunter Laser Technology, fog mode and seven selectable aiming reticles to make it possible to nail precise distances in any and all weather conditions. In addition, these devices employ a Prism Lock system that makes holding them steady less of an issue. Both are designed to be compact, rugged and waterproof, and they weigh 6.1 ounces (173 grams). There are differences between these devices, though. Significant ones. The GX-1i is tournament legal under the Rules of Golf, offering line-of-sight distance measurement only. As for the GX-2i, it may not be used legally in competition because it offers a wide range of other features. Such as True Golf Range, algorithmic software that also reads slope, altitude and temperature. In addition, a Club Selector component combines a player’s specific hitting strength and the TGR to automatically recommend the appropriate club for each shot (after golfers have input data on their usual distances).
