It is sad to hear about someone getting lost and then end up dead. I don't know if most people who go out into wilderness like that are just following trails, and or using a compass while they are hiking, exploring etc.
If one is to ENSURE of NOT getting lost ANYWHERE, BRING A COMPASS, LEARN HOW TO USE IT, LEARN how to read maps, bring a protractor, paper and pen or pencil as well! Also maps of the area if you can get them.
Also, get a backpack of ALL supplies like water, (they even have the water purification packs if you happen to find water anywhere they also come with purification osmoses bottles to make ANY water drinkable), MRE's, (they are easier to pack and light weight), first aid kits, small portable tent, batteries and a flashlight, AND A BEACON STROBE LIGHT for emergencies, (at night anyone, aircraft flying in the area can spot a beacon strobe light miles and miles away at night, etc, (regardless of you planning only making a couple hours or a day trip out of it). 100ft of 1/2in, 100ft of 3/4in ropes, (rappelling) and carabiners. EXTRA clothing! Never know when you might need them!
Yes all this stuff can weigh about 30-50 lbs, but one should get used to packing it, it could save your life! LEARN your pace count for 100 Meters, keep track of every 100 meters you travel. (with feet side by side, step off with your right foot, every time your left foot hits the ground is about 1 meter, (at NORMAL walking in case anyone doesn't know), They have plastic beads on parachute chord, (called Ranger Beads) for pace counting.
If you don't know how to use a compass and going out into those areas, you are only asking for trouble as well as NOT being prepared for supplies.
Prior military personell, (mostly grunts), can vouch for using a compass, (the military kind ONLY), NOT the compass on the clear plexiglas board.
Using the (military compass), by tracking your coordinates, WRITING DOWN, your degrees, (South 166% 352 meters as as example), heading the direction you want to go by AIMING your compass, (towards an object like a lone tree, particular mountain that stands out, etc), if you make a turn WRITE DOWN your degrees, meters traveled, when you need to find your way back out, do a reverse azimuth, (by aiming the compass numbers opposite of what you wrote down, (example, if you traveled north at 360 degrees, your reverse azimuth would be south 180 degrees).
My opinion, I don't care how much someone says they been in and out plenty of times, if I AM GOING WITH THEM, you can bet your behind I am NOT going to get lost or stranded!
