You can get a really nice portable O2 system for significantly less
than the cost of a handheld GPS. If you fly an airplane that can
get you above 10,000 easily, it really makes sense to have one. Out
here on the west coast, MEAs go up to 10-12K just to fly back and
forth between the largest cities (Portland-San Francisco, San
Francisco-Los Angeles). I spend a lot of time up there.

Thanks for all the info. Any recommendations on manufacturers? How
long does a tank last when you have four people breathing from it
instead of just the pilot?


All the best,
