Thank you for your videos Skipper. I'm currently studying DS and find your explanations clear and easy to understand.

Hi Brent, you did a simple examples. Great. But what if we have compass that gives us deviation W (e.g. 270). Is math applied? In such case we have 270+4. Right?

So when navigating do you use the chart and use True or the compass and use magnetic? Or both.

at 18.15 seconds the slide shows a title of True to Compass but is it not supposed to be Compass to True? i think...
