ive used spare air for years.. i have to admit i sometimes come up with less than recommended air in tank so i like to have it when im doing my deco. and just in case i cut it too tight. i have a back up............i have the 1.7 size which as 5 meters i think gives me about 11 breathes. why do other divers laugh at me when i bring this unit along??????? is the chance of a dive reg or tank malfunction so tiny that a spare air is just not needed? if so its needed for me cause i sometimes come up with minimal air in tank left and i only do it in the shallows............so if i did run out i got 11 breaths to get the remaining 5 meters to the surface. and finally the 1.7 versus the 3.0. i have both and i suppose i can use the regs for each other interchangable? i think so. finally i see you have to get the units sent in every 5 years to get the tank inspected. if i take care of mine is that really necessary? what do you think about regulator on my unit. i have not had it inspected in ten years. dont rubber parts in them go bad? maybe i will go for an emergency breath and nothing comes out? oh well on my tombstone i put . I saved a buck!
