What (or who) persuaded you to become a professional diver?
I graduated from Engineering school and worked in the IT industries in my early days. However, I’ve had a love for the ocean, mother nature and wildlife since I was a kid, so I guess I finally heard nature’s call. What could be better in life than having your dream job, visiting places around the world most people have never heard of and getting to meet fellow divers from around the world who share the same passion!
Describe your biggest challenge when diving.
I think the biggest challenge would be maintaining a balance between being a businessman in the dive industries and a passionate professional diving educator. The diving business is not an easy place to be and there are many bottom-lines you have to draw in order to maintain your professionalism and integrity.
Which diving achievement are you most proud of?
The proudest achievement is when you see the students and instructors you’ve taught become good divers/educators, be successful and complemented by others. You know you’ve made a difference by teaching them.
What was your first diving experience like?
My first diving experience was not very spectacular. It was more than 20 years ago learning to dive in turbid waters with near zero visibility and stormy weather in Hong Kong. But that didn’t discourage me from wanting to dive to achieve my goal.
Why do you prefer rebreather?
The sound of silence and peacefulness when diving a rebreather is something I always notice and miss when I go back to the noisy open circuit scuba. Being able to go further, deeper and longer, rebreather can take you to places that are seldom visited. And also, the ability to get really close to marine life and stay a very long time. Rebreathers can make you believe that you really belong in the ocean.
What's your favourite diving gear?
Sidemount diving is my favorite way to dive because Sidemount is such a versatile, streamlined way of diving that can truly take you anywhere, and go any place. You have to love the Sidemount Liberty CCR because it is so well laid out and fully self-contained. It’s a super comfortable, streamlined, and balanced way to dive a rebreather. Not to mention that it is also the lightest way to travel with a rebreather.
What's your favourite diving spot?
I have always been fascinated with cave diving; it was actually a very early goal that encouraged me to attend scuba lessons in the first place. Although it took me a long time to finally achieve it, the process was fun, and I still love every bit of it. Whether it’s the crystal-clear water, the vast and beautifully-decorated passages of the Mexican cenotes, or the many other places underground that are still unexplored. When you see a hole in the ground, you always wonder what is on the other side. Exploring caves is like being in a different world-there’s always allure and a sense of exploration because they are so well-hidden!
