What Our Past Students Say

With Diego as freediving trainer, I had an incredible experience of two days training. I never would have thought I could go so deep— and it was good, both physically and mentally. With patience, professionalism, and a deep understanding of the discipline, Diego guided me step by step, helping me to overcome my fears and to build a real confidence underwater. Thank you Diego!

Absolutely one of the most incredible disciplines I’ve learned in the shortest time possible. This was only made possible by Diego’s exceptional ability and skill in introducing Free Diving - from the very beginning all the way to diving alongside other skilled professionals in the industry. I discovered fears I never even knew I had.. but thanks to Diego’s expertise in this discipline, I learned how to face them head-on and push through. I conquered those fears within moments of them arising. Absolutely phenomenal work, thank you so much for your presence and the knowledge you share in all that you do. 🙏🏼🙇🏻‍♂️

I had the great pleasure to experience for the first time apnoea diving with Diego. It was such an incredible and memorable adventure. His knowledge and expertise makes you feel super safe and the trust he transmits you, makes you feel comfortable to go even deeper than you would think of. We spent 2 days in the water, covering all topics and familiarising with the deep ocean. We were in total 3 people each day, the perfect size group to learn from each other, but also for Diego to invest in each of us properly. The last day, his partner came along and did some great content creation. A nice peace of memory to hold onto and share here. I can only recommend this and I definitely got hooked.

Diego is an amazing instructor. He really helped me feel safe and stay calm. He also teaches you so much about what’s going on in the human body throughout the experience. He’s very educaed and a majestic diver. Diving helps you to understand more parts about yourself and what the human body is capable of. I highly recommend Diego to anyone looking to & will definitely be diving with him again in the future. 💙🌊

I had a great experience free diving with Diego from Breathflow Connection in Koh Samui (Koh Tao). It was only my second time doing apnea and still a bit nervous but Diego has the right words and technics to make you feel confident and have fun 💪 I highly recommend.

Awesome course. Diego was amazing, first time I’d ever done free diving. Diego was extremely motivating and attentive. He provided full guidance the entire time and made me feel incredibly safe during the dives. I would highly recommend this course!

Just had a couple of great days with Diego and Jan on the Freediving course. Diego came over to our hotel the day before the 2 day course to meet us and go through the theory and equipment for a couple of hours and brief us up on what to expect over the next two days. They picked us up and took us to the port and back each day which makes things easy and allows for more questions and answers. All wet work was done in the sea, for us that was via speed boat to Sail Rock, Koh Tao. First day we did free immersion and constant weight with fins to a max of 12 meters, practicing breath up and recovery breathing, and equalisation /technique, and then a fun swim and dives around the rock. 2nd day, was a repeat but down to 20m and also emphasis on rescues from 10m - oh and interrupted once by a whale shark! Super fun and very pleased. Thank you Diego and Jan. We loved it.

Frequently Asked Questions

Do I need Level 1 certification to take Level 2?

Yes. You must have Apnea Total Level 1, AIDA 2-star, SSI Level 1, or equivalent certification from a recognized freediving agency. You’ll need to show proof of certification when booking.

Level 1 is 2 days, max depth 20m, designed for beginners. Level 2 is 3 days, max depth 30m, and focuses on advanced equalization (Frenzel/mouthfill), rescue skills, and deep diving technique. It’s significantly more challenging.

More demanding than Level 1. You’ll do two full days of boat diving with multiple deep dives. You should be comfortable in the ocean, have good fitness, and be confident with your Level 1 skills before attempting Level 2.

Progression is individual. Most students reach 25-30m by Day 3, but the goal is safe, controlled diving—not just hitting a number. You’ll still receive certification based on your demonstrated skills and the depth you achieve comfortably.

All freediving equipment (mask, fins, wetsuit, weight belt, buoy, rope), boat trips on Days 2-3, instruction, certification, emergency oxygen, first aid kit, and online learning materials.

Your Level 1 (or equivalent) certification, towel, reef-safe sunscreen, water, and snacks for the boat. We provide all diving equipment. Avoid alcohol 24 hours before diving.
