    Cozmo was a great instructor who was able to explain the complexities of how different concentrations of oxygen can help, or in some cases be detrimental, for increasing bottom time and safety. Full disclosure, I am his son. But I am also a public school educator with more than 5 years in the profession, so I know what good teaching looks like. He is very knowledgeable and enthusiastic about the whole diving world and can share his 30 years of diving with you.
