Freediving legend and multiple World Record Holder, Carlos is perhaps best known for being the first person to dive beyond 100m in FIM and CWT (unassisted disciplines) in 2003 and 2004, dives that made history.


Apart from his impressive competitive career, Carlos is a phenomenal instructor/trainer who uses different strategies to customize each course according to his students’ needs and abilities.


While his classes are both fun and energetic, he takes the curriculum very seriously and is determined to provide the best instruction possible to his students. He himself is constantly studying and learning new techniques.

Petra Oberucova Freediving Instructor

Petra is the epitome of a real ocean lover and ocean adventurer! An exceptional diver, her true strength is in her knowledge and passion for sea life and her incredible ability to interact with the fauna around her. This sensitivity comes from her work with horses, shark research, and coral reef conservation.


Her big, beautiful smile is matched by her heart, and her love of the sea brightens everyone’s day and makes learning a truly wonderful experience. She is highly empathetic and always finds a way to relate to her students and make them feel as confident and comfortable as possible.  


In addition to this, she incorporates her artistic side through her superb underwater photography skills which you can view @Petra_Del_Mar

Get out of your comfort zone in a safe environment. Having fun while learning more about body and mind, that’s freediving for me.


If you are between 6-96 years old I can guide you in this inner experience.

Danny Peters

From an early age, Danny grew up with the beach and the sea, a passion by heart with everything surrounding these two. More than 22 years of lifeguard duties, saving lives, and affront the roughest sea conditions he eventually got in touch with Freediving!

The physiology and psychology behind freediving in combination with the state of mind when submerging underwater with one breath and only your mind and body, made freediving an instant addiction for Danny.


With experiences working on an ambulance, anesthesiology, and his lifeguard's duties; Danny not only loves to teach about Freediving but loves to dive deeper into the anatomy and medical background about this wonderful sport.


These skills combined make Danny an overall great Freedive instructor with a lot of extra in-depth information during his courses. Making sure Blue Classroom keeps providing the best quality courses, training, and workshop for both beginning and seasoned freedivers alike!
