Also, there are decoy flags that aren't on the list.

Edit: In the "forest" map the paths make sense but I'm pretty sure the map or flag coordinates are slighly off (with a flag being on a different side of a path than indicated by the coordinates).

The last land nav course I ever did was in the reserves and in the mountains. Instead of traipsing through the underbrush I just followed the fire breaks and occasionally took azimuths off surrounding mountain peaks and only missed one point because I didn't feel like hiking up the steep hill it was on top of.

Not too sure I see the value in online land nav but I also learned it before GPS was really a thing.

Tells you everything you need to know.

The orienteers I've known have been some of the brightest and fittest people I've ever met (going to Cambridge, Oxford), doing all sorts of interesting things, and are some of the best runners you can find. One of my closest orienteering friends was disappointed in running sub-2:40 in his first marathon.

I was a military land nav instructor (although not for the US military) and this was one of our biggest challenges, especially once smart phones become common. People would consider position fixing to be an unbearable waste of time and would inevitably waste hours of time and effort because of it.

1. Plot the point where you currently are on the map.

2. Flag that point; you only get two Grease Pencil Points, but you need to remember this forever.

3. Plot the point you want to get to. Flag that one too. (You'll need to clear the grease pencil in order to do this. Flag your location before you do.)

4. Set Point 1 to location and Point 2 to destination. Open the protractor and read the azimuth from Point 1 to Point 2. This is based on Grid North.

5. Apply the adjustment between Grid North and Magnetic North.

6. Use your compass to orient yourself along the correct azimuth. The compass uses Magnetic North. You had to make all the measurements with your fat, stubby fingers, so hope they were accurate.

7. Start walking, tracking the distance you've gone.

8. Encounter obstacles.

9. Step off the track.

10. Wander into the wilderness and starve.

(You also get a notepad; I assume the notepad is there to give you some hope of recovering if you plan out the path around an obstacle carefully.)

I'm surprised they give you the option to move forward deterministically; that's not actually a thing that humans operating outside can do.
