Vortex Diamondback

I purchased these Binoculars for a rifle elk hunt that my sons and I were going on.
We were able to compare these to a pair of Leupold Pro Guide binoculars and a pair of Vortex Crossfires. The Leupolds were 10x42s and the Crossfires were 8x42s. We all were really impressed with the clarity and brightness of the Diamondbacks in all kinds of light conditions including snow and fog. I would love to see them compared to a pair of Vortex Vipers.
I would not hesitate to purchase another pair for any hunting situation.
