Thanks, Leff. Do you have a suggestion for lead hardness and, since you use a mechanical pencil (I've always preferred them) thickness?
These are the dividers that I use. I use it almost exclusively with the pencil lead in one of the arms (for marking off distances on the chart) instead of dual steel points. I haven't tried the ones that SD mentions, but they can be bought from Weems and Plath also.

I haven't paid much attention to the lead hardness or thickness, but like SD mentions, softer leads will be easier on the charts. I tend towards thinner leads since I find it hard to be accurate with thicker lines (0.5mm is nice).
I learned coastal nav. with the ASA 105 text (by Tom Tursi or something like that). I wasn't blown away by the quality of the book, but it got the job done.
