I have a pair of the Cabela's brand 10x42 roof prism binoculars. These are not the "Alaskan Guide" model. I love them. They are chrystal clear, water proof and fog proof. I have had them since 1998. I have used them on hunts in Maine, NH, VT, , NY, Utah, Anticosti Island, and Newfoundland (twice). Some of the hunts had very heavy rain and snow storms and the binos performed great. No leaking or fogging.
