“What to say about Ted Harty owner of Immersion Freediving… Some may know him by Capt America, Aqua Man, team Captain of the 2012 U.S. freedive team orU.S constant weight record holder. Regardless of how you know of Ted Harty the one thing everyone can agree on is that when it comes to freedive education it’s almost impossible to top his courses.”

“I just finished Ted Harty’s Intermediate Freediver Course, and it was one of the most content-rich, empowering, and exhilarating experiences I’ve ever had.

Being a recreational athlete for over 50 years (I’m 63), I was a little cautious about what risks would exist throughout 3 days of ocean diving (it’s a 4 day course)”

Bill Kyser
Owner Special Forces Training Academy – Intermediate Course

“I live and dive, 99% in Ontario, Canada, mostly in the St. Lawrence river, the 1000 islands region. I had found freediving and spearfishing on the Internet, 2 years prior, and had ” self-taught” myself how to do it, or so I thought. Sure, I bought the stuff, and read Spearing magazine, shot fish, and dove holding my breath to do it, but that was the extent of my “knowing “, ANYTHING about safety, physiology, and techniques important to staying alive in this game.”

Cary Gibson
PFI Intermediate Course

“If, like me, you’re mainly a spearfisherman, you’ll learn a lot of things that also apply to spearfishing. In fact, everything you’ll learn applies to spearfishing as well. More than anything, if like for me this is your first freediving course, you need to approach it with an open mind: not only most (if not all) of what you learn will directly translate into spearfishing, but the approach Ted teaches is likely radically different from anything you’ve known or done so far.”

PFI Intermediate Course

“It seemed like this was going to be a no brainer. I would just need to train to hold my breath longer. While the theory and safety aspects of the class were easy to pick up, there was one fundamental skill required in order to be a free diver that completely eluded me. The Frenzel Technique of clearing your ears. All the other divers were able to pick it up so easily. It seems my years of experience actually put me at a disadvantage. Evidently my body had naturally found a way to equalize in the past and I had been using it habitually for 38 years.”

Heather Stone
PFI Freediving Course

“First of all just to give a little background about my “freediving” prior to taking the course, I would have called myself a pretty serious spear-fishermen for the last 3-5 years diving fairly comfortably at depths ranging from 10-65feet. I had reached depths just over 80 feet on my own and by no means had any sort of comfortable hunting time there and had a personal best static breath hold of just over 3 minutes. ”

Justin Baker
PFI Intermediate Freediver Course

“Many participants of PFI courses taught by Ted Harty have written about his skill in the water, where he indeed is like a “merman:” amazingly, Ted goes down with each diver on every dive, giving feedback during the dive if possible via signals or sounds, and right after surfacing (well, he does wait for you to do the “cleansing” breaths). During the pool time and ocean dives, he proves to be an extremely patient instructor—even when someone like me keeps making the same mistake over and over, say looking down on the descent…”

Past Testimonials

Ben Alcocer – PFI Intermediate Course

The immersion intermediate freediver course taught by Ted Harty is the real deal. If you are on social media or have contacts in the freedive/spearfishing community you’ve probably heard the hype about Ted’s class in Ft Lauderdale. The hype is true. The course is awesome and I was completely blown away from start to finish. I don’t care if you’re a new diver or a seasoned veteran you will gain from this class and it is probably the single best thing you can do for your diving. Don’t buy a new gun or a new fins, buy yourself a class with immersion. You’ll gain the tools you need to improve in all the aspects of your freediving. My learning curve went straight up in so many ways. Safety, technique, knowledge, the list goes on and on but long story short, you’re going to be stoked on this class. The curriculum structure is awesome and Ted is one hell of a teacher. Bottom line is I can’t say enough good things about my experience and you owe it to yourself to get into this class as soon as possible.

Octavio Cortes – Testimonials

Let’s begin by clarifying that calling what Ted Harty does “teaching” is a gross understatement, the word “coaching” is a better way to describe his working style with his students, and then again, this word also falls short. However you call what a true “Guru” does is a much more accurate way to define what he does during his Performance Freediving International courses. Small groups of up to five students definitely are put through each and everyone’s individual paces as he fine tunes the multiple, and complex aspects of freediving in a way that as he puts it “clicks” before the end of the course, making it feel easy, as close to natural as it comes. The experience having learned from Ted ranks among the best ones I have personally had in my life, and I was born in 1968 mind you.

In telling you a little bit about me, a better frame of reference should be attained as to how the experience may be for you. While I have always loved water, it was only by the end of 2013 that I started swimming again on a regular basis, mainly due to the fact that a community pool was finally at my disposal. Even after starting, I had a back injury that had me flirt with loosing my ability to walk, which also set my coming into the sport a good deal behind what would otherwise have been a very smooth start. In short, you can say I have been revolving around freediving for about two years by the time I took this Level Two course, I had also taken Freediving Instructors International Level One last year with Martin Stepanek, still with some concern about my back at the time.

I am definitely not a sports person, or a fanatic of exercising, but merely a weekender type who also swims on a regular basis for general good health, both physical, and mental, but enough about me. If there is one thing I have dialed in, in life by my almost half a century of existence, it has to be that everything in life is accomplished by using a little theory, and lots of practice. The percentages may slightly change depending on the field in question, but there is always a preference about the hands on approach, the learn as you do, the learn on the job as you may, and Ted Harty definitely follows this valuable golden rate, this winning formula during his courses. It is not surprising students really improve no matter what their individual levels of freediving are at the beginning of the course. As expected some people are great performers, and some people face challenges, and the beauty of how the class developed was that everyone benefits from everyone else’s performance too. Some errors overlapped among some of us, and some were very particular to some of the individuals. The insight however was always personalized for each, and shared by everyone as well.

Safety was paramount at all times, and provided by very close supervision by Ted himself all the while all of us were also made to follow the same surface safety procedures necessary for each and every dive. The last diver would provide, and practice the safety protocols for the following diver, we all got our share of diving, and our share of providing safety for each other. Simulated rescues at depth were also fun, Ted is a big guy which makes it even more fun, and challenging, also a good actor.

One thing that I would like to mention is the fact that Ted is a mayor character; perhaps his experience as a musician permeates his demeanor in the way of a performer, which in turn make the class highly intense, and extremely engaging. Never a dull moment, not even a pause unless necessary, not a single moment of wasted time, yet at the same time all impromptu questions that arose were addressed almost immediately in a way that everything connected with sense, and in a very easy to learn way that also felt effortless.
I doubt that every course gets the privilege our class had, but we also got to taste Ted’s already legendary hand at the Green Egg, even the vegetarian student tried it, and most important, praised it. Now, I did say taste, it was no more than a little bite, one that I still taste upon recall, and that I also hope to get a chance to enjoy for good one day.
Thanks Ted Harty, may you live for ever, and continue doing the outstanding job you are doing.

Ralph Fuentes – PFI Freediver Course

My name is Ralph Fuentes and I have been freediving and Spearfishing for about 36 years in the Miami/Florida Keys area. In addition, I have been a certified scuba diver since 1980. Like many, I enrolled in Immersion’s three day PFI freediver course to acquire the knowledge and techniques to increase my bottom time and dive deeper in order to spear larger fish. 

After many years of researching freediving courses and instructors, I chose Immersion freediving over the others because; Ted is a full-time instructor – and that’s his chosen career, and he has been an instructor since 2005. He owns the boat used for the ocean sessions – a big plus. His classes are limited to 5 students which create an intimate and personal experience. Besides, he’s an accomplished freediver and competitor! 

Before taking Ted’s class, my spearfishing depth was between 15 to 35 feet with the occasional dive to around 45 feet. My best static apnea was a 3:32 minute breath hold. My personal best dive was a 60 foot dive at one of Florida’s natural springs, and, of course, that dive was done under duress. When Spearfishing with my buddies, what I consider to be safe practice was being able to see them from 15, 20 and 30 yards away and communicating by whistling/calling out to check on each other. “That’s what we called being safe”. I know now, after completing the course, that spearfishing that way is not safe! 

During the course, I performed a static apnea breath hold of 3:30 which is the maximum allowed for this course and a personal BEST DIVE TO 66ft, with a total dive time of around 1min 23 sec. That dive was not under duress and thanks to Ted, it was calm, relaxing and under my control! What an awesome feeling!

 After taking Ted’s freediver course, I realized that it’s not just about learning the techniques to dive deeper and staying longer but how to do it safely. In his course, Ted’s curriculum revolves around the safety aspects of freediving and the practice of those safety protocols and techniques throughout the three days. I have to say, that the course is intense and not just physically demanding but mentally challenging as well. That being said, Ted’s passion, devotion and teaching style helps overcome those obstacles and amount of material covered. 

Ted, It was a pleasure meeting you. You made me feel as though we’ve been friends for years, and in the near future, I will be enrolling in the intermediate class.

All the best,

Ralph Fuentes
66 foot safe freediver!!!!

Noel Skwiot – Testimonial

Ted Harty is a record holding competitive freediver who is eager to share the “secrets” to successful diving to depth-safely. While he continues to seek out new information about the sport’s techniques from top professionals that he is acquainted with, he willing shares this information in the training course.

His Immersion Freediving course combines topics on safety in water with breath-hold and diving techniques that enabled me to overcome my limitations with getting to depth with relative comfort. The course is procedural in that Ted presents a process during class session (whether in water or classroom) and then patiently coaches students of knowledge learned to achieve success with that process. Then the processes are combined for successful safe deep diving in relative comfort.

Ted’s Immersion Freediving course has absolutely improved my breath-hold, safety, and the way I dive. He will recognize any inefficiencies you have with your dive and with corrections enable you to perform better, safer, and with greater comfort deeper. I highly recommend this course for everyone, especially those “highly experienced” spearfishermen.

Joe Dudley – PFI Intermediate Course

Ted this was one of the best classes I have taken in a long time and I feel this in the biggest jump I have done and properly. I really enjoyed the safety aspect of the class and it put things in great perspective. I will be practicing the stretches and holds. There are a lot of things that I can take from the course and use them in other parts of my life. Thank you for the great opportunity to take this with you and keep up the great work.

Jason Buchheim – PFI Intermediate Course

I thank you for teaching us all this great knowledge about Freediving!  I guarantee you that through this course I will be a much safer freediver!!!

I had some bad habits that are hard to break, but I take it seriously and will absolutely break them (ie, keeping snorkel in mouth freediving, blowing bubbles when no mouthpiece in mouth, I learned all this from my PADI courses from 1985 and it has been ingrained in my brain)  I probably was not your favorite student as I kept making silly mistakes and my rhythm sucks (you should see me try to dance)- but I do take it all seriously and am sincerely trying my best and hopefully improving.

Thank you, you are a great instructor!

Tyson Ward – PFI Freediver Course

My name is Tyson Ward, I am 31 years old, a Professional Firefighter/Paramedic for 10 years, and have been freediving/spearfishing for the past 16 years. I signed up for Ted’s course for same reason I suspect many others do, I wanted to dive deeper, stay longer, and shoot bigger fish! What I did not realize was that I would not only be given the tools to make those things possible, but I would learn how to do so safer than I had ever done before. Within the first 2 hours of class I discovered several habits that needed to be corrected and Ted was there every step of the way to help me reprogram. Ted also provided excellent explanations based on science and/or personal experience. When you have a pool of instructors such as PFI you better believe the information you receive is the best. 

 Like many others I considered myself “safe” based solely on the fact that I have never experienced a black out or Loss of Motor Control, that I know of. While this may be true, as the class went on I became aware of a few times that I may have been closer than I would like to admit. The good news to all this? Ted will show you the way. There is no ego, no intimidation, and no shaming. Ted provides you with the knowledge and skills to recognize and intervene should you ever witness a Loss of Motor Control (LMC) or blackout. Ted mentions that he now has 7 former students that have recognized and successfully intervened in a LMC or Blackout occurrence and I, without a doubt, expect that number to grow as he and his fellow PFI Instructors change the culture of spearfisherman and freedivers alike.

 Was Ted able to make good on his promise of diving deeper, staying longer, and being safer? Ted delivered in spades. 3 days before class out of curiosity I performed a static breath hold of 1:45. On the first day of class 2:45. Before this course the deepest I had ever been was 42 feet. On the second day of the course I hit 66 feet (course max) and felt as comfortable as I normally do at 25 feet. Ted performed every dive with every student and reinforced safe practices by having students act as spotters and safeties after every breath hold regardless. Ted also takes photos and videos so you can see how to correct your entry, kick, or any other technique that needs to be addressed.

 Immersion Freediving has a great thing going. I cannot recommend taking Ted’s course enough! I look forward to his intermediate course in the future as I now have a new confidence and comfort level that I have never before experienced. I thank you and my family thanks you for giving me the tools to be a safer and better freediver. Thanks again Ted!
