I was a map & stopwatch man until I was offered a second-hand Magellan 310. It only has 100 landmarks and one 10-leg route. But it does tell you where to point the aircraft. OK, so it won't tell you zone boundaries, frequencies or runway directions, but I like looking at maps and doing pre-flight planning.
I'm now a GPS convert. I find I'm spending less time worrying about where I am and more time concentrating on the flying, although I still draw lines on maps and would never fly without one.
Having praised the basic model Magellan, I'd like to upgrade to a Pilot 3, but it costs 4 hours flying and I question whether I would get the value from it.
