Cressi Supernova Dry snorkel review

[jadairiii]

In my opinion Farallon one of the best....ample bore clean and clear and bends where they should be.. big fan of Farallon....that snorkel great and that mask was a winner for SCUBA but too high volume for freediving....

Never used the mask. I have made one "modification" to my Farallon. I separated the barrel and rotated it back about a 1/4 of a turn, re-glued it in. I always found that in rough water when I was hunting and looking down the Farallon "ate" water a bit, that modification made a very good snorkel great!

Good mod....comfort with snorkel when spending hours hunting is essential...moldable bite pieces I used but never felt I needed...and as I remember they could accumulate crud....

Remembering that SWB gives almost zero or zero warning....I knew of freedivers [none I would dive with] that went deep for abalone and if in doubt of exertion expended or distance to surface would release wt belt and hold with one hand with the idea that if SWB occurred they would release wts and float unconscious to surface...unconscious and floating at surface almost always means drowning...again in my world this is not what competent or prudent freedivers would practice. Nothing is important enough on a freedive to jeopardize your survival.

Just my experiences and opinions; not for everyone and I could be wrong!

What I really like about this post is that no opinion is dogmatically represented here.

A short story that happened to me during a too long and deep freedive.
When I realized that I probably wouldn't make it to the surface I dropped my weight belt.
Then it went black and the first thing when I regained consciousness was lying high on the surface breathing heavily through my snorkel.
Without the snorkel with my face in the water I could have drowned.

That may be the case most of the time, but with myself I have the impression that the conscious mind slowly withdraws and unconscious behavior makes room.
I have blown out the snorkel over a thousand times, and I registered that I was at the surface by tilting into the horizontal position. If you drop the weight belt it happens by itself.
Keeping the snorkel in your mouth, blowing it out at the right time and surviving for a short time without conscious thought is possible. As a freediver you practise this all the time at a lesser extent, which saves a lot of oxygen.
The diving described by dcvf page 1 # 8 is much safer, but who will give up freediving if he has no buddy or float on the surface to grab ?

Dang! That was not just that you were experienced freediving [muscle memory] and had the skills wired...but were indeed lucky! Close, very close...

Let me add a tip to those that don't do a lot of freediving....if you "overstay" and are swimming to the surface while seriously hypoxic remember NOT to fin hard for the surface....doing so as the ambient pressure drop future reduces oxygen Pp from the CNS, finning vigorously will put the oxygen/blood needed to stay conscious into the leg muscles and future 'starve' the CNS/brain tissue resulting in a more rapid SWB.... stay calm and don't over-exert.....of course if in doubt drop weights which will help you getting to the surface conscious with less muscle movement.

An addendum....it is my opinion and experience that all diving is in fact solo diving, you are it....especially true when freediving as each diver has different agendas, different descent and ascent paths/rates and of course differing bottom times....judgement and skill sets keep you safe not another diver or surface support....again my experience only over decades of diving and diver supervision....but to each their own.
