"Was a hard but great course! Thanks a lot again to all staff who teaches and prepared us so well, that finally the IE was easy going! Thanks Matt, Tina, Steph, Kenji, Steve, Manu and everybody else who supports us."

Bernd

"They cater to your schedule during divemaster training so you can do it at your own pace and are also environmentally conscious which is an important factor. Anyone considering a professional career in diving should definitely consider Crystal."

Kristi

"They are very dedicated, and were always there to help me with the theory, and to improve my scuba teaching skills. If you are still searching for a centre to do your IDC at, I recommend doing it with Matt."

Dina

"There was absolutely nothing that could have happened during the IE the candidates were not made very well aware of. Everything ran so smoothly for the candidates."

Muzaffa

"It's a good decision to do your training with Matt, a lot of information is given and shared experiences. If you guys wanted to do IDC, I recommend doing it with IDC Koh Tao. Thank you for the amazing IDC."

Mohamad

"If you guy's are looking for good teachers and the best Course Director, this is the place..Thank you for guiding us, inspiring us and making us what we are today. Highly recommend."

Azie

"I enjoyed every single day of my IDC as well as my MSDT. Matt is an outstanding Course Director who goes all the way out for you, in preparation for the IE."

Eric

"The course was fun and you meet a bunch of new people, it’s not hard to fit in. When the day of the IE arrives, you don't even stress about it, because the Course Directors are the best."

Jasper

"Did my IDC with Crystal Dive and IDC Koh Tao and I'm so happy I chose them. Matt Bolton made sure that there was lots of learning, training and laughs! I felt more than prepared for the I.E. And it showed!"
