What if their grandmother had two wheels? Why ... she'd be a bicycle!Dan I like you but this is a bit cavalier....
Even a diver with good buoyancy shouldn't be doing this without appropriate training. What if they go OOA at depth and switch to the "pony" bottle? What if they add a second slung bottle and now they are doing gas switches at depth without knowing the gas switch procedure--if they've been carrying one bottle for years, then carrying two bottles shouldn't be a big deal, right? What if they don't mark it appropriately and someone on the boat mistakes it for their stage?
Recreational nitrox certifies you to 40% mixes. Much better idea to use those mixes you've been trained in to try to make your safety stop safer.
Carrying one slung bottle and knowing enough to not use it below 20 feet does not impress me as complex enough to warrant a course.
