I have afew of his books (couldnt tell you which one, got SOOO many survival books!) but he often talks about his "possibles bag". I get the impression this is his survival kit, he DOES carry a firesteel, tinder, matches in Matchsafe, and some cordage) but he certainly seems not to carry too much hi-tech gear.
His courses here in the UK are supposed to be excellent but places are booked up MONTHS & MONTHS in advance
