I can recommend this dive center with no hesitation to anyone out there. I have tried two other centers on the island and these guys were absolutely the best in many respects. Whether you want to do certification or fun dives, you will be looked after.
Although myself and my wife have done Advanced Open Water before we went to Gili Air, we were definitely not advanced divers and really just starting on our great diving adventure. We wanted a place where we felt safe, pushed ourselves, skill up and also actually just enjoy the dives and have fun. We achieved all these with the super helpful and so knowledgeable dive instructors. During our time there we dived with 5 different instructors, and each and every one of them was professional, helpful and looked after your experience. Wish every center was like that.
The dives were very safe, the professionalism of dive instructors went way above what I expected, each dive place was assessed for current, visibility, safety and overall satisfaction factor and when these were not aligned we simply moved to another dive site. I have improved so much as a diver by just observing, listening and discussing some small aspects of my dives with dive instructors. My skill levels improved immensely overall by just making these small adjustments each time.
Very safe, professional and fun. Go for it, you will not regret it.
