Compass vs. GPS....Jim, they both have their place. I prefer map and compass for the simplicity. When hiking, I rarely have to navigate to within feet of a target.
Plus, I've cached water off trail, marked the waypoint, and the GPS had me 300 feet (a football field sized error) off target when I got back around to re-supply, with WAAS. A map and compass triangulation had me dead on. I use both when in doubt. On trail, and with a good view, one compass bearing to a feature is all you need to find your place on a mapped trail.
I don't like GPS's in cars, even though I have one, it's just too much of a distraction.
I LOVE my GPS in the kayak or powerboat....it measures speed, plus, it helps me find all those nice creeks and waterfalls that sometimes aren't obvious on a map.
Plus, I don't have to stop paddling to see where I am. This all comes in real handy when out on a craggy lake with lots of coves, or crossing big water in wind and waves.
