  I recently completed sidemount and Deco 50 courses with Gili Divers Tech, and I cannot recommend Clem highly enough for her exceptional teaching and technical expertise. From stress management to how to react when losing a stage, every detail of the courses was guided perfectly. Thank you to both Clem and Gili Divers Tech for the amazing experience 🙂‍↕️

  I recently completed my Sidemount and Advamced Deco courses at Gili Divers! I loved the structure it followed and the logic of it. the dry sessions were very good and I loved all the explanations Clem gave us. the confined session were conducted in the sea which I enjoyed very much. The dives were very good despite my computer giving us the shortest ndls to ever exist and I liked how much we could do again and again all the skills to practice. I also really enjoyed doing it with 2 more people which made the course super fun!

  I did the Deco 50 course here with clem. The course was run really well. There was plenty of time to go through the theory and make sure that we understood all of the safety procedures that we need to follow. The dives were excellent. Tunang and Linda’s are amazing divesites and I highly recommend going to them. The support staff were very helpful and really helped out while getting ready. Great experience and I can highly recommend.

  I just completed my sidemount course at Gili Divers, Trawangan, and I can’t recommend Clem highly enough. Clem is the technical diving instructor at Gili Divers, and she is outstanding — incredibly knowledgeable, patient, and professional, with a real passion for sidemount diving. She took the time to explain everything clearly, made sure my setup was perfectly dialed in, and tailored the course to my skill level so I felt challenged but never overwhelmed. What really stood out was the level of safety and organisation. Everything was extremely well planned, clearly briefed, and executed to a much higher standard than other dive shops I’ve trained or dived with. Her calm teaching style and attention to detail made a huge difference to my confidence, trim, and overall control in the water. On top of that, the dives were fun, relaxed, and very well organised. If you’re thinking about doing a sidemount or any technical diving course at Gili Divers, ask for Clem — you won’t regret it!
