I still like a Douglas protractor, but I use the parallel rules as an antique. The Plotter is my mainstay. After I demonstrate all 3, almost all of my students opt for the Portland Plotter. Jack Portland Plotter? I'll do a search on it. I hate the parallel rules because they are hard to use with the chart spread on a pitching cabin floor. Instead I use my hand bearing compass mounted to aplastic square I can align with north and perpendicular to the edge of the chart. I have a protractor mounted to it so I can rotate it about the compass axis. Works for me. Around here, in most cases, i can ignore the difference between magnetic north and true north. I seriously considered the Fujinon 10X50 binocs with internal compass but decided that I have never wanted to take a bearing on anything with binocs so bought the ones without the compass. So, I still use my trusty Suunto hand compass (the kind with the mirror) that has lasted through many caving and sailing trips. |
