Summary: These are heavy, really heavy (that's why I gave only 4 stars) In the rest all other reviewers are right: good optics, rugged design, waterproof, adjustable for each eye. Don't be scared by the color.
Summary: Like MOST marine binoculars these are individual eye focus. This works great for astronomy because you are looking at far away objects. Once you focus, you never have to focus again. Crystal clear images. No fogging. A bit heavy, but wow, what a view. Quality constructed binocular, case and strap. Highly recommended.
Summary: I like it. It's clear and magnifies well. Good for a single user. For multible users it takes adjusting each eye individually each time, which if you are not patient can be a problem. Good for the price for single user.
Summary: The paperwork included in this package shows a center distance focus. It says to focus left eye, then right eye and then use center knob to focus for distance. There Is not center knob to focus.
Summary: We bought these binoculars to leave in a rental for our guests. The problem with most binoculars, even the so-called rubber-clad ones, is that the first time they are dropped or knocked hard, they get misaligned - so when you look through them, you get two images that can't be merged! In other words, they are useless. This is the first set of binoculars which has survived a year of use - and with luck, will survive more years of use.
