freediving after shallow scuba dive

[ptoot]

Does anyone of you know whether it's bad to go freediving almost immediately after a shallow scubadive (10 meters) of -say- 45 minutes? :naughty

if so: how long should we wait?

Freediving will not be much deeper than the scuba dive.

Thanks!

You are mixing apples with pears in terms of Nitrogen tracking. I wouldn't bother trying to find out if you get bent by doing it. Use the Scuba and flying recomendations as a guideline as to when you can freedive safely afterwards.

All that up and down, compressing and recompressing of Nitrogen bubbles can shunt the bubbles into places where you don't want them like your brain = neurological problems.

Do one discipline each day.

Have a safe dive

Don't do it. Search my posts on other threads about this to find out why

I still have a slight limp on bad days 6 years after freediving post scuba - and that was a 16 hour interval!

(sorry to hear that)

Thank you for sharing your experience and points of view. I flipped a coin and will go freediving tomorrow, scuba will be some other day...

Thanks again for the input, it's tempting to regard shallow dives as completely harmless from a desaturation point of view... I like the 'one discipline per day' rule.

Freediving every day

is no need to flip a coin....
u can allways do freedive prior to scuba dive...never the reverse....
once i was one hour [with 40m max depth] in scuba, and because my body cried for free immersion, i did go at nearly 16m in freedive after 15 minute of my scuba exit....
that was the day of my life.....4 hours of heart fribrillations....
since than i did only one freedive at 17m after a scuba session [2 hours interval]...it was allright, BUT what i did was WRONG

one a day doesn't always work. you need to treat freediving after scuba like flying after scuba, so you may have times when it will take 18 or even 24 hours before you are ready to freedive. My freedive when I got bent was 16 hours (the next day) after a scuba dive to 40m. Get a computer and wait for the no fly signal to go

or just follow Steve (apneaboy)'s rule, which is pretty much what I do these days...

The problem with computers are that they quite often only give you a few hours no fly time. Stick to the tables recommendations and over 24 hours for deco diving then freediving as a minimum.

Apples and pears.

Freediving doesn't give you that much Nitrogen compared to scuba but we treat it so badly that is why it can cause problems.

You can receive good answers of your question by searching this question in Google........

well skaks I think you get a better answer here than in google but welcome to the forums I'm sure your savage into freediving.

all the naui an padi scubadiver instructors that i had asked told me the same thing:
is strictly forbiten to freedive after scubadiving
i took theyr words for good!!!
althought the naui dive table begin wit 12m depth and you dive is at 10 m, allways take those 10 m as 12m for safety...and the 45' take it to be 50'
so!
45 minutes at 10 meters is ennough nitrogen in your body to prevent you for freediving a period of time, named surface time....
normally you must spend a lot of time at the surface, because to calculate the next depth and dive time with this table is usless...you want freediving not scuba
and for that reason you will take a breath from the surface and go with it at 12 meter [for example]
the ascention rate is big...is not allowed even in scubadiving to ascent so quickly, no matter the circumstances are...
in extra i will tell you that the fatigue has a word to say in that action....
i say u can go at 12 meters after at least 2,30 hours of scuba diving at 10m for 45'
why risking?

Is there any risk of getting bent while freediving? (no other activities)


What about freediving after flying?

Yes carlos coste got a bad bend but for mere mortals like me doing regular 10m dives highly unlikely. That said hydrate well and give a decent surface interval between dives.

What about freediving after flying?

Again guessing here but on shallow dives with normal duration I cant see there being a problem but we dealing with so many variables ie shallow dives but for hours on end or just one-two hours or deep dives but only 3 of them, properly hydrated or dehtydrated, fit or unfit.
Imho give plenty of time or ease back on it and keep well hydrated. If in doubt o2.

Eric F has had some bad experiances with dcs from freediving but again he is not my the mere mortals category afaik.
