Great open sea binoculars - Barska Deep Sea 7x50mm Porro Prism Rangefinder Binoculars

I purchased the binoculars for nautical use. I used them on a whale watching trip. Had 5-6 foot swells, but was able to use binoculars with little effort. The reason I gave a 4 for easy to set up and usability is based on the lack of user-friendly instructions for the rangefinder. Eventually I will figure it out. All-in-all, I really like the binoculars.
Pros: Works great on the open sea. Floats. Durable.
Cons: No good instructions on how to use range finder. Caps for upper and lower lenses are loose and don't stay on very well.
