The Fii ( Freediving Instructors International) education system that we offer sets the standard in Freediving Safety as we were the first ever freediving education system to be insured. These courses were created and developed by 13x freediving world record holder Martin Stepanek. Daniel Koval, owner of DFI (Deep Freediving Instruction) , is a student of Martin's and has gone on to become the deepest freediver in all of North America diving to depths over 110m/360ft on a single breath of air. Daniel started his freediving school in 2011 and has been making the freediving and spearfishing community safer with each and every course.

Daniel not only teaches freediving at the highest level, but also competes internationally in the most prestige competitions around the world. His dedication to the sport has earned him 6 US National records, 2 North American Continental records, and 2 consecutive years of bronze medals at the CMAS World Championships. With over a decade of experience free diving, Daniel has been able to share his incredible amount of knowledge in the sport to help others progress steadily and most importantly safely.
