My only negative is weight. That being said these are serious quality and will last a lifetime. My main use is for locating water and critters. I have some 10x50 Nikons that are OK. These are only 7x50 BUT!!! I can see the bugs at 300 yards where there is surface water. It ain't happening with the Nikons! Also a ton of my viewing is at dusk or while traveling at night, if there is any moon these are better than night vision.
Pros: LIGHT Transmission, Clarity, Boob Proof
Cons: Weight, rear lenses covers could be better
