I said this before and I say this again: no accordeons and no valves.

Hi Wallowa your #10

Wow...tiny bore on #3 and a lot of hydrodynamic/wind drag, plus failure point at valve #1....leaking valve or failed valve, forget snorkel...

I know but my wife refuses to change #3 it’s here choice !
This snorkel #1 doesn’t have any valve failure since 1992 !!

do not understand why removal of snorkel before freedive is a 'safety issue'..
I don't argue with the rules established by AIDA instructors (I'm a 3* AIDA, etc.)
I abide by them.
My experiences since 1965: no samba, no blackout (and the rules are now the same by "Apnea Academy" (1* There) and SSI Freediving (2* there) and Lifras in Belgium (3* there)

I explain what I experienced before joining AIDA in 2013.
It was on December 20, 2003 in Sharm El Sheikh in the Red Sea.
I was preparing for the S3 (Lifras) certification. See the test details
Epreuves en eau libre pour le "S3" Lifras

I descended to 21m and set off "horizontally" for 10m.
When I looked at my depth gauge, I was at 24m ( I was in negative buoyancy), that's when I felt a strange unpleasant sensation in my throat... I had my snorkel in my mouth because at that time we didn't talk about the safety rule that I learned later in 2013 at AIDA (no snorkel in your mouth underwater). Since 20/12/2003 I decided to no longer keep a snorkel in my mouth underwater because it can trigger the swallowing reflex... that's what I had at 24 m (~80 ft)
The swallowing reflex : risk is swallowing water... followed by drowning
swallowing reflex
And of course, only those who didn't drown could answer. ;-o ))

when spearfishing you do it to eliminate bubbles escaping snorkel on descent that could spoke fish.....
Yes I know

Regarding "SW blackout" (Google translate will help you)
Syncope Hypoxique
Syncope can still occur 30 seconds after completing the exit protocol (so that the AIDA judges can formalize the dive)

Good post and it is about snorkel use.... :cool:

I think I see the disconnect concerning the AIDA snorkel standards discussion on this thread and what I will term recreational freediving [non-competitive]...the AIDA is primarily for competitive depth-record freediving...whole different game...in fact most if not all competitors lay on their backs to 'breath up and lower heart rate' before the dive and never use a snorkel..."swallow reflex" is pressure related and not due to presence of snorkel mouthpiece [swallowing reflex] again related to extreme static or competitive apnea dives...SWB after surfacing is again an artifact of competitive deep apnea competitions and unrelated to snorkel use..

Look, follow the tenets and skills you have developed......but with or without a snorkel if a person suffers SWB they made a serious judgement error and I would not emulate them....stay safe and enjoy the drops....freediving is a joy.


    • AIDA International: The International Association for the Development of Apnea (AIDA) is one of the most recognized governing bodies for competitive freediving. It manages records, organizes competitions, and sets standards for freediving education.
 
The swallowing reflex can occur when holding something in your mouth... like the mouthpiece of a snorkel !
 
I'm reminded of the (I thought) comical comment made by a "guide" on a snorkeling trip in Maui, while explaining the gear (mask and snorkel) to the customers. "See this? This is a valve, it lets water out of the snorkel. If it doesn't have this, it's not a snorkel - it's just a tube". As I sat there looking at my valve-less SEAC "tube".
