Fishing big water most the year or at least water with color to it made me kind of forget how important polarized glasses had been in spotting fish.
I remember back to the day of beating the banks when I was a high school and college kid. I felt naked without them.
Now, with this clear water we have, I've found I need them more than ever again.
On one recent trip there were two of us with glasses and one without. The client that had them saw about 15 steelhead while guy that didn't have them only saw one fish. That's an eye opener
One problem with beeing able to see the fish though is that they can see you too. Sometimes that's not the greatest. Try and avoid wearing bright colors so that you don't stand out like a beacon to the fish.
When choosing polarized glasses there are a couple different colored lenses. The amber is best for low light/over cast and the smoke is best for bright sunny days.
