“I did my full cave course with Alain back in 2011. At that time, I was a beginner, not much experience, and Alain managed to teach all the core skills needed for any kind of technical diving. We were two students during our training, with opposite background. However, Alain managed to show both of us what we had to improve, and our strengths and weaknesses. All the explanations were clear and he had total control underwater, giving us enough time to practice and master the skills. The certification was definitely earnt, not given!
Since then, I've done further technical training and became an instructor myself. However, after all of those courses, I'm so glad I did that very first training with Alain. It laid all the basics, core skills, mindset and emergencies procedure for any further class I took. By far the best and most challenging course I have ever taken! Thanks my friend.”
