I don’t have the Viper, but I do have the HD series, which is the top of the line for Vortex. Everything is excellent about the binocular with one exception.The center focus is terrible. I’ve been on 2 hunting trips in the past 2 months and I was refocusing it everytime I turned around. I called Vortex and they suggested I send them in. I started looking at the Vortex line at a local store and they have same problem on the intire line. Outside of this I like everything about the binocular. To me it’s bad enough where I’d probably buy a differentd brand.
