The bushnell yardage pro 500 uses 6X magnification and can display distances in yards or meters. If the course has bushnell yardage pro reflectors or reflective tape on the flag sticks this unit will perform easily beyond 200 yards. Measuring distances from tee boxes to doglegs, bunkers and hazards is simple and fast. On larger targets the model 500 easily works to its rated range. When ranging to the pin, the yardage pro 500 works best when used within 150 yards. Yardage pro laser rang finders are a great practice tool and will enhance your ability to build the touch neccessary to score around the greens.
