Considering they're electronics, they are bound to become outdated. First rangefinder I ever had was lucky to range a deer at 400 yards. Then I had a rangefinder that would range deer out to 600 and compensate the angle telling me what I should hold at for a shot. Now my rangefinder ranges deer out past 1200 yards and takes into consideration the barometric pressure, temperature, and predetermined ballistics.
Throw in the warranty on the RF of only 2 years and the optically better EL Swarovision and a light Leica 1600-b fits my preferences more.
