I started a Bushnell PinSeeker 1500 review in 2005 with the sentence "Tiger Woods has long said that the secret to good golf is always being pin high." A lot has changed since 2005, but Tiger's advice still rings true.
What has changed is that three years ago rangefinders and GPS units were a rarity. In 2005, these types of devices were illegal. Since 2006, they've been legal for tournament play under a local rule, and it seems as though every serious golfer has one (or more!) in their bags. The market has expanded quickly, and the early guys in - Bushnell with laser rangefinders and SkyGolf with GPS - are being challenged at every turn.
One of the challengers in the laser rangefinder category is longtime rifle scope-maker Leupold (& Stevens) with their GX-I and GX-II laser rangefinders. These rangefinders notably improve upon the venerable PinSeeker 1500 in just about the only ways I think a laser rangefinder can really be improved: by adding features, making it smaller, and shaving a hundred bucks off the asking price.
I've put the GX-I to a thorough test. Read on for my results.
