How To Improve Your Breathing for Scuba Diving
With enough practice and calm you’re going to stop cursing your pressure gauge for sending you back to the surface and start hating your bottom timer, because you have to be back at the boat in five minutes but you still have plenty of gas left in the tank. It’s also better for the group if everybody is better on air because if there’s an incident and you need to share your air supply whilst on a safety stop then I’d rather have too much air than not enough.

The most important thing about scuba diving is that you do it safely. And that is what Safe Diving is all about.
On this channel, I will discuss all aspects of going underwater from equipment advice and techniques to the little things like what to pack in your bags for a dive trip.
My entire professional career has been spent in and around the scuba diving industry and travelling to diving destinations both warm and cold.

One thing i found really helped, was doing some simple pool or confined water dives during which i would deliberately concentrate on breathing, calm, smooth, and of a suitable ryhythm etc. On "real" dives i found there was simply too much going on to be able to concentrate on specific skills. So time in pool, despite being really boring (;-) is useful!

I once had to donate air to an experienced diver who had been so busy clearing his constantly flooding mask that he forgot to monitor his SPG. Apparently, a decent mask (or having a spare one on you) is good for your air consumption, too.

how do you keep your buoyancy constant while breathing in for 4 seconds holding and then breathing out for 6? Wouldn't you go up and down in the water?

Mark, I’m glad you started your own channel. Get info brother.

Dude you're so close to 100 subs!! 🙌🎉

Great video Mark. Does opening or closing the Effort Control knob on the 2nd stage have any effect on SAC?

Hi Mark - just had a random thought... if I’m on Nitrox and my dive buddy is on air and one of us has an out of air emergency - for whatever reason - what’s the ramifications of sharing Nitrox/air?

Mark and fellow divers, There's appears to be a basic misunderstandings about breathing represented here. It has to do with Oxygen and the use of Carbon Dioxide. (Anyone who wants to research should go to Patrick McKeown's Oxygen Advantage info.) More oxygen in the lungs does not put more oxygen in the cells, where you need it. Having enough CO2 in the blood is necessary to drive the oxygen into the cells. Slow breathing into the bottom of the lungs - which is where oxygen is most easily absorbed - also allows CO2 to build up. This makes experiential sense. Watch a competent diver breathe. I suspect you'll see them doing just that. FYI: Mark's 4 x 6 breathing is perfectly in line with McKeown's information.

I use a thing called combat breathing. Take 4 seconds to breath in, hold that breath for 4 seconds, then 4 seconds to blow it out. Rinse and repeat.

Never hold your breath underwater that’s how over expansion injuries happen 🤦‍♂️
