A free online safety course for freedivers, spearos and breath-holders. Make sure you and your friends make it back to the dock every time.

“I want to do more to stop the needless fatalities from shallow water blackout than any other person on the planet.That's why I created freedivingsafety.com and made it free for everyone.”Ted Harty
This is the story of a fatal solo diving incident, and the hard truth behind it: even a 26-year veteran diver didn't know the safety techniques that could have prevented it. Not until he went through Ted's free safety course. Watch this before you get in the water again.
The techniques that could have changed that outcome are exactly what this free course teaches.
Within three weeks of launching this course, a spearo saved his buddy's life from an underwater blackout, simply by going through this free training.
By the end, you'll know how to save your buddy's life from a blackout.
Not at depth. After 2 or 3 breaths at the end of a dive. And most of the time nobody is watching: 8 out of 10 blackout victims have no buddy next to them.
The whole way up you are seconds away from blacking out, and there is no warning. You can feel completely fine and be out cold 10 seconds later.
You will learn the exact recovery breathing pattern we teach, why hyperventilation is the thing that gets people killed, and the one rule that makes blackout a non-issue: never dive alone.
If your buddy blacks out, seconds decide the outcome. You will learn the exact steps to bring them back: what to do, in what order, and why it works.
Not because it's flashy, but because shallow water blackout is the risk nobody wants to talk about. Every diver knows it exists, but believes it won't happen to them.
My free safety course goes far deeper than a 60-second clip ever could. The life you save could be your best friend or even your own.
Recovery breathing and dive habits that prevent blackouts before they happen.
Step-by-step blackout rescue you can perform under pressure.
Why blackouts strike without warning, and how to never rely on 'feeling fine'.

I'm Ted Harty, founder of Immersion Freediving. My deepest freedive is 279 ft, my longest breath hold is 7 minutes, and I'm a past USA Freediving record holder. I've been a Performance Freediving Instructor Trainer since 2009.
I never liked that life-saving safety information was hidden behind the paywall of an expensive freediving class. What if there's no instructor within 200 miles of you? What if you can't afford a class? So sad, too bad?
That's why I made this course free, so anyone can learn to be a safer freediver. It's not a substitute for an in-person course, but it's a great start.
This life-saving information will always be free because it's desperately needed in the freediving and spearfishing community. Learn how to make it back to the dock every time.
I look forward to teaching you to be a safer diver. Ted
