Hi Steve and all, I neglected to mention that Karen's dial using just fingers tells north and the time without any other tools than fingers, a rough estimate of the Latitude, a knowledge of the method and of course having the sun out. As a result one can know the time and direction in an unprepared situation within 15 minutes of time and easily 10 degrees of direction. I've found this quite useful when I've been without a watch or wondered what direction something was. It also staves off withdrawal from other sundial watching! :-) Your experience may vary.
Hope this helps! Edley -
