"Congratulations on a first-class idea. I have been diving for more than 10 years. While the concept of the buddy system is meant to provide safety, my opinion is that it is an almost total waste of time. In my experience, 90% of the time the buddy is nowhere near you to perform a rescue. In my case, I am usually paired with a complete stranger on a submarine. Will that person be watching me? Forget it! I used Spare Air for the first time a few days ago in the Caymans and felt really safe and deep for the first time."

"I believe the Spare Air is the most important piece of diving equipment I carry. I have long given up the false sense of security that buddy-breathing and octopus breathers provide."
Larry Toigo, West Des Moines, IA

"I am a PADI-certified Open Water, Advanced Open Water and Rescue diver. I first started using my SPARE AIR when I started doing underwater video, and seemed to spend most of my dive alone. Later, I started reading about the idea of 'Buddy-less' diving, as I would so often dive and mate with someone I did not know, let alone their diving skills. This concern and the fact that I was a Rescue-certified diver led me to the conclusion that a SPARE AIR was the safest and wisest 'back-up' system to use. Not only is it a truly redundant air supply, if you encounter a diver with no air underwater, chances are he will quickly panic if he doesn't get some air quickly, and one of the safest things to do is simply to give the diver your SPARE AIR and get away from him until he calms down. Then you can get to him and help him to the surface. And I must say that I am much more confident getting out of a bad situation by having a SPARE AIR within reach instead of an octopus."

"While diving, I am a proponent of 'Murphy's Law' and I think it is important to have an alternative air source because I am not impressed with the way divers in general practice the Buddy system."
