I would have thought that the "mock compass" would be the easiest for a beginner to use rather than the map screen. For those of us that are a bit map challenged and have to turn our maps in the direction we are going, the arrow is so much easier.
I was a rank beginner when I wrote that and immediately found the map more informative and easier to orient myself and know how close to the cache I am.
If you follow the instructions on that page you don't have to turn maps in any direction. The map always points in the direction you are moving and shows the cache in relation to you and the direction you are going.
I have my map set as north always facing up. To use the map in the way that you mention, I'd have to reset my map display to course up. I prefer to know what direction I'm headed. It's just a personal preference for this simple mind. I have read very little of your guide because by the time it came around, I was no longer considering myself a beginner. I'm sure that there is stuff in your guide that I could learn from, but since what I'm using is working for me, I think that I'll just stick with it.
