Yes, his stuff is good, same for the Hill People Gear vids, Michael Bane wrote a pretty good book on the subject.
The whole comms thing as Paulides, GJM and others have cited is an often overlooked aspect of this general subject. Mrs. Fatdog put her foot down a few years ago about this and I am not allowed to head for the forest either 4wd or hiking, without being actively tracked and having the sat phone in tow along with the cell. She knows she will be a widow some day, just doesn't want to fight the insurance company over if I am missing or dead.
One of the things the rescue services, like the Clay Co. rescue team who finally responded to this poor girl's call for help always preach over and over again, if you need help in the TNF and cannot tell us your GPS coordinates it will take us a lot longer to find you. I think a lot of people wander into the woods in this part of the country and always assume they will be able to find bars on the cell signal and it will give responders their location too. Ain't so unless you have the new Apple sat capability.
