Freediving Instructor review of my online equalizing course

I have more and more instructors purchasing my Frenzel course for $10 per student. This way I can teach their students to learn Frenzel BEFORE they show up for their freediving class.
This saves he instructors so much time, allows more students to meet the depth requirements, and get better reviews.
If you are an instructor reach out to me if you are interested in having me teach your students how to Frenzel.
Here is the link to the Frenzel equalizing course.
