This has to be a best buy if you do not need a bino that is not submersible. Clarity and contrast is almost as good as my ED Pentax 8x32. Edge clarity is not as good as the Pentax because of Pentax's aspheric lenses ( at 3x cost).I own the the original 7x26 custom compact single coating
designed almost 30 years ago for NASA. This third or fourth generation upgrade of a classic will most likely be my all purpose field optic.
Pros: Sharpness of original 7x26 NASA design from 30 yrs ago with increased contrast and weather proofing.
Cons: None for the price
