Rudi Castineyra's freediving clinic packed a lifetime of techniques, skills, excercises, and physiology into five intense, action-packed days. At the end of the class I was able to hold my breath longer, and dive deeper than ever before in Northern California's chilly, dark 52-degree water. It's hard to say what helped more, the breathing techniques, streamlined movements, or learning the incredible physiology that goes on within the body on every descent. Throughout the course Rudi emphasized safety, presenting each technique in a thoughtful, concise, step-by-step manner. This course is a must for every serious freediver.

"I used to be a synchronized swimmer for many years, and this helped me reach depths of 30 meters easily a few times, but I really didn't know how I did it, I had no idea about right techniques or proper breathing and I didn't pay much attention to it. Rudi's courses gave me much knowledge and I learned to breathe correctly before dives and to equalize in shallow and deep water. He opened the freediving world, its beauty and its craftiness to me. He taught me that this is not only a beautiful sport but a dangerous one if you don't take it seriously. I learned that to be good in freediving you have to be smart, strong and wise. I am much obliged to Rudi and Yasemin for their great professional attitude and the passion they shared with all of us, as well as the incredible care they took of us"

"I have been freediving for over 20 years now, been a scuba diving instructor and even became a candidate for the Master of Sports, which gives me a strong training background. However, it wasn't until I took Rudi's courses that I realized his system is really unique. Following this system I was able to double my results in just a matter of months. The more important about these courses is that, thanks to Rudi's sincere and convincing words, I finally started to dive in a really safe way, something I never did before"
