Sporty's Pilot Shop tested the Altus oxygen tank monitor and has given it rave reviews. They loved the ability to put psi, flow rate, and time remaining wirelessly on your iOS device. Also, the Siri notifications of FAA oxygen warnings and the built in altimeter amazed. They definitely see the vision and we are so grateful for their willingness to be open minded to this new product.
