For birding and scenery viewing while hiing mountains, the light weight of these binoculars is appreciated, especially over my 7x50s. (But, those larger ones were purchased for another purpose, anyway.) My wife and I both like these Eagle 87x42s. A good bang for the buck.
Pros: light weight, good optics
Cons: none
