The CaddyView Version 3 rangefinder with Pin-Validation & Slope functions by Caddytek comes with a “Mode Switching Button” to switch between Non-Slope mode (indicated by a green LED) and Slope mode (indicated by a red LED). It lets the golfer easily adjust this rangefinder to the slope mode in a friendly/practice round of golf or to the non-slope mode during serious tournaments. The “FlagSeeking” technology with the pin-validation function identifies the closest target with a slight vibration to help you get your measurement to the flagstick, no matter what is behind the green. The powerful 6x magnification and fast responding optic also help you range an object’s distance up to 800 yards (250 yards to the flag) effortlessly and clearly. The Magnet Suction Plate lets you attach the rangefinder to the golf cart’s metal frame conveniently for easy access during the round. CaddyView V3 is large enough to use comfortably and compact enough for easy storage. This laser rangefinder from CaddyTek will be a powerful tool for managing your golf game. Enjoy the game with CaddyTek.
