Great for the price. I bought a nice pair of binoculars in 1969 and they worked great until last year when my boat sank and it didn't survive. (Water has entered the left lens) In fact, the right side is still working. But anyway, on the Bar Marine Corps they are really understandable and I like the features, buoyancy, water resistance, range finder and glowing compass. They're only good for one person because of the individual focus adjustment, but for a hundred bucks you can buy a pair for everyone in the boat and have plenty of spares in case one falls overboard and swims away. Of course they are not Swarovski, but at my age,
