Leon is a class act, and the Meg is really one of, if not the best, CCR's currently made.

I had the great fortune of knowing Leon for a little more than ten years, and working with him for 3 of those.

If there is a better CCR Instructor on the planet (heck, the known universe), I am unaware of who that might be.

A couple of the many things that makes Leon shine are his discipline and honesty. He builds the Meg, was a Combat Dive Instructor and Combat Dive Supervisor in the US Army Special Forces. He has forgotten more about diving rebreathers than most people will ever know, yet Leon goes through the pre-dive checklist on his Meg before every dive, without fail. This level of discipline and leadership simply isnt common.

No matter what CCR you buy and dive, taking a course with Leon would be a rewarding experience.
