Calculating Range

[Captain Birdseye]

Thank you macjim, I have started a career and am waiting for my contact so I can try this method out.

When I have practised, I can use the ruler to make my first bearing, but when it comes to my second, I cannot place a mark on top of my subs position due to a ruler mark already being there, it thinks I just want to move the existing mark, does anyone else have the same issue?

Totally normal, a simple solution is to drag the line a bit over your actual position so it ends behind you.
