Simon Timmins is an excellent and friendly Dive instructor. The 3-day course I had was fun and I learned a lot from it. Simon taught me the theory and the skills and he was very good at teaching it. On the 2nd day, it was time to dive on open sea. Simon taught me the basic skills and he supervised me well as I performed them. Simon was very attentive so I felt safe on my time under the water. On the last day, after some basic skills test, I get to go dive deeper. This was the best part of the course. I got to see plenty of marine life and corals close-up. If you ever decide to learn diving or go diving in Mactan, I recommend Mr. Simon Timmins to bo your guide/instructor.
