MY MISSION

“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
Why this course exists

26 years of diving. One dive that should never have been fatal.

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.

Proof it works

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.

What will you learn?

Four fundamental safety principles

By the end, you'll know how to save your buddy's life from a blackout.

KNOW

Principle One: 90% of blackouts happen at the surface

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.

BEWARE

Principle Number Two: Why you can feel fine seconds before a blackout

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.

PREVENT

Principle Three: The specific breathing technique that reduces blackout risk

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.

RESPOND

Principle Number Four: How to save your buddy's life

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.

A reel seen by over a million freedivers

Why did a reel about blackouts go viral?

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.

Trusted by the Discovery Channel, Tim Kennedy, Ben Greenfield, a SEAL instructor, and the CEO of Twitter, Jack Dorsey.

Why I built this

I used that award money to build freedivingsafety.com. Two weeks later it was live.

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.

The life you save may be your own.

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
