Freediving after diving?

[Nsearch]

Is it safe to freedive after diving? I've been diving on the barge just about 12 miles wsw from Ft. Desoto (the one with all the huge jews on it), I believe it may be called the Permit Barge? Anywho.....earlier this yr the vis was just incredible and after my second dive (max depth is 60 fsw) I was swimming around and decided to take the anchor line down with gun in hand. I successfully made it down 3 times with time to spare down there.....got a funny look from another diver :D but I didn't shoot any fish.

I was just wondering if this is a bad thing to do, whether I were diving comp air or nitrox.

Thanks.

I would think that so long as you don't do it immediately after coming out of a decompression dive, you should be ok.

True......thx Marcus. Have another easy question for ya....how do change the text that's under the avatar image next to your screen name? Your's is *Member what?*, mine is Member. Can't find out how to change that......thx.


Anyone else have any opinions about freediving after diving?

Freediving after diving on compressed gases has been know to trigger DCS. I do it all the time, but would not recommend it after several dives or one deep dive.

Deep dive being 80+ or what? Everyone's opinion of a deep dive can be different.....

Thanks though.....I didn't think it would be the smartest thing to do after diving :)

This is one of the many stupid things that I actually learned to stop doing before I ever hurt myself. You can check out why here: http://www.wkpp.org/articles/Decompression/why_we_do_not_bounce_dive_after_diving.htm

Thanks swimndive, good info!

Unfortunately, this is one of the things that isn't taught when getting your certification.

Thx swimndive, that article pretty much explains the *why* in don't freedive after diving. Guess I was lucky :eek:

coming from someone who does it just go for it

freediveing after diveing isnt that god of an idea the repetive dives can jump start dcs. The bubbles in your system well be compressed, move alitte and the reexpand.
this is how it was explained to me, free dive first to see if there are any fish on the wrecks, then dive them.

You should check out Deeperblue.net. The site has alot of good freedivers and you could search previuos posts to answer your questions.

Freedivers can and do get bent just freediving, if it's intense enough. I just completed the Performance Freediving Advanced Course taught by Kirk Krack and his record holding associates, it was very informative. He really knows his stuff, and has had DCS from just aggressive freediving.
As in all things, moderation is the key. I freedove as the human bottom finder to find fish, all day long for years, then followed that up with tanks on spots from 50 to 70 feet in the days before affordable Lorans. Fortunately there were plenty of fish in those depths, and I didn't push it deeper. I never got bent but I was in great shape and maybe I was just lucky too.
Using a dive computer with a desaturation time feature would be wise to monitor the level of N2 you have absorbed. And then using a freediving computer, like a Mosquito or D3 from Suunto would at least give you a record of the freediving you have done. There are no guidelines, to my knowledge, but some things in diving are still experimental.
I would avoid variable balast freediving until you really know your capabilities with constant balast freediving. It's a good way to get in over your head, and black outs are unforgiving! Keep a one up, one down watch on each other. Just so you know... about 90% of freediving black outs occur after the diver has hit the surface and breathed!

Insearchoffish: By the way the Permit Barge, aka Betty Rose, is NW of Ft Desoto in 45 ft of water. It sounds like you might have been on the South Jack Wreck in 60 ft, not a barge, but an old unknown ship, note the boiler in the center of the wreck.

Good diving & be safe!

I wouldn't take the chance, remember after you breath compressed gases you have displaced nitrogen thruout different body compartment, tissues ....And remembering that the laws of physics demand that it takes a while to completely Off Gas.

If you are in great shape, who knows, Probably may not get hit. If there is a chink in the armor, e.g. "Age","out of shape",?higher Fat/ muscle ratios", "slight cold","a buried subtle infection you may not be aware of" all of these can and do affect metabolism" .

Not worth the chance displacing existing nitrogen gases in the body, either driving them deeper into tissues or vice versa.

I wouldn't do it, but than again I am conservative!

this is something that is very well taught here in Italy, also because most of our dives are deep (below 30mt - 120 feet) and the bubbles in your body are recompressed and moved somewhere else when you freedive.
What we do here is diving in the afternoon when searching a new spot, and the go spearfishing early the morning after.
We can only do spearfishin without tanks.
