Can we adjust for magnetic variation before we put the compass to the map? Or do we have to do it as you showed? Just asking because I had added in my notes that I need to do that first, but then I rewatched your video and you did it afterwards.
Hello Sunny, just seen your message. Measure your grid bearing first, then adjust. Think of it as converting your grid bearing (map), into a magnetic bearing (land).
Adjust for magnetic variation after taking your bearing. You are adjusting from grid to magnetic bearing. Measure grid of the grid (map) then adjust. Thanks, Jane
Nice video but it does not tell why any nunber of degrees are needed to be ADDED when going from map to compass and what to ADD or to net when grid north an magnetic north is used. She also does not state that nearly all maps are made to orientate to true north which us why adjustnents are needed and what to do if magnetic north is east of your location or what to add and or subtract depending on where your grid and magnetic north indicators read with respect to the age of the map as indicated in the key, and how to approximate magnetic to true north by using a Polaris sighting - without Google. And how to plot when compass to map calculations are needed. Complete understanding of this is necessary whenever the need for using a compass is called for.
She gives a general explanation beginning at the 1:45 mark. Then at the 2:10 mark, she advises to go look up more information on how to make the adjustments, as explaining it here would add too much time to a short and quick video. So she does acknowledge it, and does tell you to go find that information somewhere else. I think it was a great way to handle it, regarding what this particular was trying to accomplish.
