Image stabilized binoculars
The Canon stabilized binoculars are nice but not waterproof. I read several reviews where the stabilization system stopped working after a year. The presumption was that the salt water envioroment was the cause. The Nikon Stabileyes are waterproof but cost more than the Canons. I bought a pair of Nikon factory reconditioned 12x35's on Ebay for $600. They were sold as a "demo" pair but were in reality-factory reconditioned. I am very satisfied with them.
