For super-accuracy, you would need to write down a bearing and distance every 100 feet. For reasonable accuracy, you can draw a vector on a piece of paper. (It doesn't have to be accurate.) What I usually do is record the bearing and distance and draw the vectors until I get close to the destination. Then I compute my exact location and go from there.

In most cases, the distance you will travel while depending on the compass will only a few hundred feet. The end game is learning how to set up a search pattern to find yourself should you lose the trail.

I use a lensatic compass, so I hold the compass near my face. If I have a camera in my shirt pocket, it will affect the compass.

I'll eventually send you an excel program to draw maps. I think it does use macros. It has been awhile since I've used it.
