Vortex Optics Viper (10x42) Binocular

I recently purchased the Vortex Vipers to use on my annual Colorado elk/deer hunt and can not say enough good about them. The optics are superior to anything I've used in the past, which constist of Pentax, Nikons, and others. They are light weight, great for hunting all day. They are very good in low light situations, glassing early and late, and they are rugged. They are quick to focus and adjust and the adjustments say put until you change them. The eye cups stay extended until you retrack them. All in all, very nice binos. I would recommend them to anyone spending any time in the field.
