Julien Fortin

Julien is 37 years old, born in France, though he has been living everywhere but in France for the past 18 years - and India is the place he calls home. He has a background in engineering, but figured out that teaching Scuba Diving would be more fun. After having worked in the automotive industry, in IT, in web design, in sustainable development, and doing the odd jobs as driver, kindergarden manager, writer or climbing teacher, he therefore became a PADI instructor.

He's been diving for close to 15 years, and since he enjoys traveling, has been exploring the underwater world in California, Cambodia, Cuba, France, India, Malaysia, Mexico, Philippines, Senegal, Sri Lanka, Switzerland, Thailand... And taught more than 600 courses in the process.

He can teach courses in English, French and German - and guide divers in Spanish, Tamil or Hindi as well. Training professionals, being Divemasters, Assistant Instructors or EFRI instructors, is something he loves, as he enjoys sharing tips and tricks about the job and teaching strategies - but Technical Diving courses is one of his not-so-secret passions, which a special weakness for Sidemount, Cave Diving, Deep and Trimix diving.

Some people hate diving theory - Julien is definitely not one of them, and will know no mercy: after enjoying a full day in the sun carrying gear and exploring the depths in all conditions, he won't mind spending hours teaching you all about the background of diving, until your head spins.

All our instructors are Technical Divers and at least Staff Instructors

Oxygen Window: a Triple Shot

1st of March, 2016 - by Julien

The “Oxygen Window” is one of those concepts that are heavily discussed in technical diving, yet often misunderstood. One of the main reasons for this misunderstanding might be that there are several definitions of the Oxygen Window, which are somewhat related, but nevertheless quite different, and focusing on either off-gasing rate, bubble formation risk, or both. This article attempts to summarize and simplify 3 definitions, based on a variety of different sources, especially including the excellent “Deco for Divers”, by Mark Powell, and the very thorough “Gas exchanges, Partial Pressure Gradients and the Oxygen Window”, by Johnny E. Brian.
Under pressure: hot tanks

1st of February, 2016 - by Julien

Warning: geeky article ahead! When calculating the pressure variation in a SCUBA cylinder when the temperature of the cylinder changes, the method given in some text books and old PADI IDC exams (1 ºC = 0.6 bar) provides slightly different results than the calculations derived from the Ideal Gas Law. This article intends to demonstrate how that approximation and the Ideal Gas Law are related, and why the two methods are almost equivalent.
Tec Diving: is Depth an Objective?

1st of November, 2015 - by Julien

Depth is not an objective - it is a circumstance to a given mission: visiting a particular place, exploring a specific wreck or cave, seeing a rare form of marine life, carrying on a certain project. Admittedly, the nuance may be subtle, and the border between a circumstance and a mission blurry at times. If you're taking a TEC course, for instance, performance requirements define a minimum depth for each dive - how is that not a goal, since you don't meet the objective without reaching that depth?
Not becoming a fossil in a cave

15th of October, 2015 - by Julien

Lying in the silt, the fossil of a turtle is greeting me with a foolish grin and empty orbits. When asked what they would like to become whey they grow up, little kids usually answer something along the lines of fireman, doctor, teacher or cosmonaut. In the depth of this Mexican cenote, an underwater cave halfway across the globe from home, I found a new calling: when I grow-up, I want to become a better cave diver - and, if possible, not a dead fossil in a cave. Even a turtle one with a funny smile.
