I said I was just practicing on the paper chart. Using the plotter to check the accuracy of my work. Nothing more. I don't always get free time to practice plotting on paper. Just kinda surprised...

:) I Mentioned it in more than one post before.

This was the point of my post. I can set my plotter (Lowrance HDS8) to show magnetic for EVERYTHING BUT the course planner, which is ONLY true! I would prefer it to be more consistant.

They used almost the same words I used earlier - they use magnetic because "it is what the compass uses".

I don't know why I would use true, if I had to adjust for variation for every leg. And...

I mentioned (post 11) it is a lowrance HDS8. Great plotter.. but very strange that the course plotting tool is only in true. I called Lowrance to see how to change it.. Never got a call back. Posted...

You have to do 2 steps to go from T to C (var, dev calc). Going from M to C is one (just dev). Since variation wont change, in...

If you start out at magnetic instead of true, wouldn't you be one step ahead? Just account for deviation? mdc instead of tvmdc ? (accounting for changed in variation if it changes in the course)
