I hear more negative snorkel stories than I do happy ones.
Plus a snorkel doesn't work underwater which is a big possibility in our local surf conditions. Been there done that, thank goodness for a reg in my mouth. Not one of my regular dive buddies uses a snorkel and they all use long hoses.
More reason to practice. We were required to do a 50yd duck and swim on snorkel for my scientific class. UCSD came up with the test I believe, to simulate a surf entry with scuba (although we didn't test suited with scuba).
I also did a heavy surf entry at Big Creek fully suited in scuba, using my snorkel to save air; so I know it's possible. You won't believe how much air you use just to count 60m of kelp
There are pros and cons for everything I guess. I'm learning that with this long hose thread
One really nice benefit I rarely see mentioned with a long hose is it wraps tightly to your body not protruding out far from your head.
This keeps the kelp monster from pushing the reg around in your mouth and even worse your buddy using their special fins (AKA hands) when swimming and accidentally pulling the reg out of your mouth.
I would say that a 90 degree or 360 swivel would work just the same
It is a proven fact many panicked divers will grab the reg from your mouth. With a long hose it already is the one you are trained to donate and your back up is bungeed close to your chin for easy delivery into your mouth. You will always know right were your backup reg is. Too many times I see people with their octos dragging in the sand. The chances of them finding it quickly are slim.
This was one thing that I forgot to mention. Using a config where your would wrap the hose around your head, I just imagine an OOA grabbing your reg and pulling your head towards them.
We often scooter dive and need to be able to perform air shares so a long hose is mandatory in my book.
Something I never thought of =]
I have now had two instances where I have had to share air. Both times I was glad to have a long hose. If you want to be close, grab hold of them. If you want a little distance then you can separate a little and the person OOA hangs onto the hose so it doesn't get pulled out of their mouth. The long hose gives you that option. The short hose does not.
Plus you can easily share air when someone is low on air before they run out. We have done that to lengthen safety stop times when someone was low on air. We have also shared air when one of my buddies was low just to extend the dive and not have to surface. He still had over 500 psi in his own tank to safely ascend, should the need have arisen.
