I came upon this actually simple, effective idea in a small gem…The Little Red Book of Fly Fishing by Kirk Deeter and Charlie Meyers. The late Mr. Meyers (C.M. in the book) offers up the idea of carrying a small pair of binoculars when fishing to scout a body of water for fish activity. He mentions being higher up on say an embankment. I wonder if this might work from a perch on a pontoon or drift boat on a lake. Couldn’t hurt to have them for hillside observations of deer, elk, bear or tree top eagles. 

This is a nice little book for beginners. Deeter & Meyers provided practical information for the novice fly fisher and good refresher info for us all.
