When guiding archery hunters, it is important to have an accurate yardage reading when a shot presents itself. Most bow hunters will have their own rangefinder, but I felt it important to be able to provide a backup reading. The Vortex 850 had amazing reviews, and backed by a no questions asked warranty. The Impact 850 is extremely compact, and has great glass. I have used it on the golf course and while shooting the bow and I love it. It will be an invaluable guiding tool and one that will be attached to my bino harness at all times.
