Summary: Quite ok, but it has a worse contrast in lower light conditions in comparison with dome other versions in this price, like Barska 7x50 Waterproof with fully multi coating. But it has good field of view and autofocus is also ok.
Summary: These bino's look to be a direct substitute for the Tasco Marine 7x50 bino's which I have two sets of to compare the Konus to. The Konus actually hold a few line more of resolution versus the Tasco, they are lighter than the Tasco and provide a more rigid tripod attachment for glassing for prolong periods of time while hunting.
Pros: Lighter, than Tasco Marine 7x50, better designed tripod attachment for prolong viewing, excellent eye relief
Cons: carrying case is a much lighter material than the Tasco Marine bino, and no Rubicon coating for glare
