The minute hand isn't used - that would cause the angle (or half angle) to change much too quickly (the Sun traverses the sky at 15° per hour, while the minute hand rotates at 360° per hour). It's between the hour hand and 12 o'clock on the watch. The north / south line is half-way between those two. The orientation of north and south then depends on whether it's before or after noon. For best accuracy, the watch must be set to local noon (in the northern hemisphere, Sun due south at noon, regardless of time zone or daylight savings).I need no batteries. In the day time, point the hour hand of an analog watch at the sun.
South is always 1/2 way to the minute hand. If I'm wrong here, I need to go out for a refresher tomorrow.
My tree, plant and bird ID is pretty hopeless (I know some, but it's shocking how many I don't know). Knots are so-so - I know the ones I've known for years, but seem to forget new ones if I don't use them regularly. I struggle with methods of making fire that don't involve using a naked flame (and preferably some scrunched-up paper and lighter fluid), although I can happily tend a fire once it's going. I'm pretty good at navigation and making things. By far, however, my biggest failing is not getting out to practice stuff (sometimes, life just gets in the way, and I do have other interests which bushcraft has taken a back seat to for some time).
