Thoughts and opinions...please. A friend of mine has a problem with depth over about 20 feet or so. Just wondering how many people had issues trusting their life support equipment when they first started diving. I mean, if you're at 20 feet and you have catastrophic failure of your 1st stage, you can simply surface fairly quick. But if you're at 60 feet, it's not going to be as easy (I usually carry a pony bottle with me, so this problem don't really cross my mind). I'm just curious if this is a normal issue, or one that is mainly limited to new divers getting use to breathing underwater. Fire away!!Thanks!
