There is a big article in the latest Dan's "Alert Diver" magazine about freediving and they did not even mention that you should not combine diving and freediving! I thought for sure it would be in there. But they do say it is ok to hyperventilate if you only stay down for a minute (?)

Has anyone else read this yet...

I know I am guilty of snorkeling around after a day of diving because I was never knew otherwise.

Al,
if you only stay down for a minute???!!! Would that be a work like crazy dive to go to 150' in 30 seconds and then swim like crazy for the surface or is that a sink down to 15' with no exertion, a stay for a bit and a float back to the surface.. all with in a minute? :Smile
That's crazy!! I'll tell you about hyperventilating. One time while training in the basement I hyperventilated, took a breath and started walking... didn't get half way up the stairs before I passed out! Fortunately... I didn't get half way up the stairs!! Hyperventilating can almost completely take away the urge to breath.. add in some physical activity like swimming and you have a formula for disaster. having an urge to breath is a life saver. It's better to build up to a longer comfortable breath hold by doing successive breath holds with good breath ups.
I've never been close to being bent by freediving I'm sure but I wouldn't want to be dropping down to 70 or 100' a bunch of times after doing a scuba dive. Doesn't sound like a good thing to be doing, especially after all the reports of people getting bent doing just that.
I'm no expert but.....

It just goes to show you can't always believe what you read (or didn't read - in this case don't mix freediving after scuba or that hyperventilating is sometimes OK).

More and more I will believe an experienced diver over an agency, magazine or manual. I assume it is the fear of liability about what is put down in print... but get a couple beers into a diver and you will get lots of opinions!

I know that a lot of the books still state that limited hyperventialtion is OK, but they were written by scuba instructors and not freediving instructors. No real freediver would ever recomend hyperventilation as a way to stay down longer.

The real key to longer breath-holds are to do a bunch of them, statics, in a row to get yourself into 'dive mode'. Slow 'yoga' breaths are the way to go.

When it comes to freediving after a scuba dive I would limit my depth to less than 10', 5' is more like it, and make sure that your properly hydrated. I also wouldn't do it after any kind of technical dive. Snorkeling on the surface would ok.
