Sam Houston, Lancair’s senior test pilot says:
‘I won’t leave the ground without my portable EDS system!’

I can fly the Columbia-300 from Bend, Oregon and all the way to Oshkosh and back on one oxygen charge. My system is about the size and volume of a modest flight bag, but lighter. It seems the guys at Mountain High did to oxygen systems what the transistor did for the radio. Made it smaller and easy to use.
