I've used Leupold range finders for years and this one is the best. Accurate point to point yardages to flags, bunkers, hills and other players on the course. Easy to use with a single hand and in windy conditions. Crystal clear view finder in all types of light. I've never used the slope device but I'm sure it is excellent. I'll never understand people who use sky caddies and watches for front, middle and back of greens when a rangefinder gives EXACT yardages to your goal. This is a great device!
