Parallel Ruler
43 in stock
Read the bearing off the ruler. Skip the compass rose. Rigid, fully transparent acrylic - no distortion. You see the line and the hazards underneath it, and you can check by eye that your course doesn't clip a single rock. 45 cm is the right size for the coastal navigation training chart. The built-in graduations let you read a bearing straight off the rule instead of walking it all the way to the compass rose. That's most useful on the Hadera chart, which doesn't have one at all. Every walk across the chart is a chance to drift. Two degrees off and the answer is wrong. Fewer steps, fewer places to lose it. Spec Length: 45 cm Material: rigid, fully transparent acrylic Built-in graduations for reading bearings Sized for the coastal navigation training chart
