Make your equalizing problems a thing of the past.

The road to success in your individual freediving journey requires an understanding and mastery of the Frenzel equalization method.

If you freedive or are learning, you already know that equalizing your ears can be one of the most frustrating issues for a freediver.


  • Do you struggle to equalize your ears in the 15-40 ft. range while freediving?
  • Have you noticed that as soon as you turn your head towards the surface, your ears clear more easily?
  • Do your ears clear fine scuba diving, but you have difficulties clearing your ears while freediving?

Let me show you why this is happening.

Pinch you nose with one hand, put your other hand on your stomach, now equalize 5 times in a row fast. If you feel your stomach clenching every time you equalize this means you are doing the Valsalva method of equalization, which is severely limiting for freedivers. Using the Valsalva method is the reason you are having the above problems. Freedivers need to use the Frenzel method of equalization.


Why learn how to Frenzel?

  • Equalize instantly and effortlessly.
  • Tired of your inability to equalize limiting how deep you can dive? Frenzel will allow you to equalize to 100ft!
  • Frenzel allows you to dive down perfectly straight without stopping or struggling to equalize.
  • Frenzel uses less energy than Valsalva
  • Watch the first video below to see how easily a freediver using Frenzel can freedive to 80ft.

I've been a full-time freediving instructor since 2009. I've had too many students tell me they had taken other freediving classes, spent hundreds of dollars (plus 2-3 days of their time) and were still unable to get past 15-30 feet in their course.

This is ultimately because they didn't learn how to Frenzel.

James Nestor freediving author of The Deep, came to me in this exact way (took a course, and was unable to get past 20 feet). After spending only 30 minutes with him just on Skype, I taught him Frenzel and off he went to become the freediving author he is today-he wrote about the experience in his book.

Why choose me to teach you how to Frenzel?

Since 2011, I've taught over 500 people how to successfully Frenzel via my one on one Skype sessions. I've been a featured speaker five years in a row at the Blue Wild Expo the largest freediving and Spearfishing expo in the United States. In 2018, I was asked to give a presentation on the difference between Valsalva and Frenzel and why freedivers should be using Frenzel. Check out the first testimonial of my student who read countless articles, watched every video he could find, even took a freediving class elsewhere, and never could learn how to Frenzel, until he enrolled in this course.


I'm known throughout the freediving industry as the "equalizing guy." Freediving instructors recommend me to their students that have problems equalizing their ears.

I've taken my proven step by step method that I have used to teach over 500 people how to Frenzel, and transferred it into this online course, Road Map to Frenzel.

This course contains the following:

    • 13 videos (lessons) with over two hours of content on my proven step by step method to learn how to Frenzel.
    • You can ask questions on each lesson, and I will personally answer every one.
    • An in-depth video discussing the risks associated with Freediving and proven simple procedures to increase your safety.
    • 4 Bonus videos, the most common ear injury and how to avoid it, tips on how to prevent ear infections, general equalizing tips not related to Frenzel, and how to stop your mask from fogging,



Once you get into my class any future updates I make to it, you’ll get them completely for free - just for purchasing.

As time goes on my course will become more costly to get into, but you’ll benefit for life by getting in now - even if the cost goes up - it won’t go up for you.


If you go through the program and I don't teach you to Frenzel within 30 days, I will offer you a full refund.







I’ve been a NAUI SCUBA Instructor since 1972, so I’ve spent plenty of time in the water both with students and for my own recreation.

I took a freediving course 2 years ago, and struggled with clearing my ears on my drops, mainly because I was using the Valsalva method to try to equalize.

I knew that I needed to learn the Frenzel method, so I read many articles on the procedure, I watched as many videos on it as I could find, but I never got a good result until I just took your online Frenzel course! I now EASILY can do Frenzel, and want to thank you so much for your clear and easy to follow steps to successfully accomplishing the Frenzel equalization method.

I also want to let you know that I’m a broadcast sports video producer, and I’m very critical of the video and audio quality of anything I watch on a screen. Your lighting, camera angles, and especially audio are all top notch, which I feel helped me to “get it” with Frenzel much faster and easier than any of the other poorer quality videos I watched.

Thanks again Ted, well done, I’m a happy student, and wish you and all your future students all the best with your online training!

Any time I hear anyone complaining about their ears I always say the same thing, “Talk to Ted.” He's known throughout the industry as the guy that can fix people struggling with clearing issues. There is no one out there that know more about teaching people to equalize than Ted.


- Jeromy Gamble, Owner - Spearing Magazine

Before I met Ted I couldn’t freedive past 15ft because of the horrible painful pressure in my ears. Ted broke down the "Frenzel" equalizing method into a series of easily understandable and accomplishable tasks. By following his steps and practicing I was able to learn Frenzel and progress from 15ft to 70ft during his Intermediate course with zero issues equalizing my ears.


. - Ben Greenfield, Founder - Bengreenfieldfitness.com

If you can't equalize quickly and consistently you'll be stuck in the shallows. Equalizing is everything. After trying, and failing, to figure it all out over a few months, I finally found Ted. His no-frills, precise, clear-cut approach to this nutty thing called the Frenzel technique instantly opened up the depths of the deep blue.

Are you equalizing correctly?

Watch this video to find out if you are doing the Valsalva method of equalization.

I started my underwater adventures (career) in 2005, as a Scuba Instructor in the Florida Keys. During that time I became a PADI Staff Instructor, and taught for NAUI and the SSI as well. I took my very first professional freediving course with Performance Freediving International (PFI) in 2008, taught by Kirk Krack. I was absolutely blown away by the class and by freediving, I quickly became obsessed...like I do with many things!


In 2009, I became a freediving instructor for PFI and I’ve been teaching freediving full time ever since. I went to my first freediving competition in 2009, as an out of shape and overweight ex-scuba instructor, and progressed from an 80 ft. to 177 ft. dive in just 3 weeks! After that experience, I wondered what I could do if I got in shape and took training more seriously. I went on to break a USA Freediving record, have won 3 freediving competitions, was selected to be Captain of Men's USA Freediving team at the World Championships, am a PFI Instructor Trainer and my deepest freedive to date is 279 feet.


While I enjoy being a competitive freediver immensely, my true passion has always been teaching. Thus, for the past 5 years I've been focused on the instructional side of freediving by teaching my classes through my company Immersion Freediving. Deeper Blue reviewed my 4 day PFI Intermediate freediving course and said it was the most professional course in the dive industry they had seen in 33 years. See the full review here.


I've worked with Tim Kennedy (US Army Ranger, UFC fighter and star of History Channel show Hunting Hitler), Ben Greenfield (fitness guru and podcaster), and several elite military instructors. I’ve appeared on The Spear, Noob Spearo, Ben Greenfield’s podcast; have written an article for every issue of Spearing Magazine since 2013, as well as am the official freediving course of Spearing Magazine. I’ve appeared in the books Deep Freediving, Renegade Science, What the Ocean Tells Us About Ourselves and One Breath. I have also been a featured speaker at the Blue Wild Expo, the largest freediving and spearfishing expo in the US 5 years running.
