    Re: Estimating height of eye

    Bruce, you wrote:

    Yes, this is my preferred method under many circumstances. To elaborate a bit on your description, I go right down to the water's edge, and then turn around and look straight level at the rocks or other features on the shore side. Most of us can get a level this way that's accurate within a few inches without any special tool, but you could also bring along a common bubble level and sight along it. You look for a spot at that height, level with your eyes from the first spot, where you can stand, and you walk to that second location. Then you repeat the process. I'm comfortable with this procedure for heights of eye within less than 5%.
