Advanced Open Water Course

The advanced open water course is designed to expose you to more challenging diving conditions and activities whilst under the supervision of an experienced instructor. The goal is to make you a better diver by increasing your confidence and independence as a recreational diver. In order to start the course the candidate must already be an open water diver, qualified to dive to 18 meters.

The advanced course consists of 5 dives over a 2-3day period. The course is very much about diving and does not have the amount of theory as the Open Water Diver course does, it´s all about learning by doing!

The only mandatory adventure dive is the Deep Dive so you will have another 4 elective dives to choose from to make it five. The Advanced Open Water Diver license results in a qualification to dive down to 30 meters.


Deep Adventure Dive is one of the two core dives of the Advanced Course. As you learned during your Open Water course, there are a number of factors to keep in mind and procedures to observe in order to stay safe when we go deeper than 18 meters.

The presence of your instructor offers security the first time you venture deep enough to experience increased air consumption and the potential of Nitrogen Narcosis.


The second of the two core dives in the Advanced Open Water course. Navigation is the adventure dive about skills of knowing were you are. It may seem like magic to you when your Divemaster takes you on a long dive and finishes exactly back were you started. But it isn’t that. With the Navigation Dive and the continued use of the navigation skills you learn during the course you will gain a lot of confidence in your location.

Peak Performance Buoyancy

The pure purpose of this adventure dive is to work on your buoyancy skills to the point that you will notice a significant improvement in your air consumption. You will also be able to get far closer to your target if you are a photographer without disturbing the environment. Better buoyancy control means better dives!

Drift Adventure Dive

We are fortunate here on Gili Air to have many sites around which are perfect for drift diving. If you have never done it before you will probably find it quite exciting! The basic skills of current check, negative water entry, reef hook deployment, taking advantage of current eddies, the difference in buddy procedures and surface marker buoy deployment are all covered.

Adventure Night Dive

Why go scuba diving at night? Because it’s very exciting and offer you the opportunity of seeing a lot of species which you will only ever see at night. The different buddy procedures, entry/exit procedures, light handling and navigation skills required are covered in detail.

Search & Recovery Adventure Dive

Once dropped in the sea things tend to stay lost. If you choose this adventure dive we will show you some of the techniques for locating items and bringing them back to the surface. Good navigation skills are vital for success.

Underwater Photography

During this dive you will learn about composition camera care, use of light framing and red balance and much more. We will also teach you some extra buoyancy skills required to significantly improve your underwater photos.

Fish ID

Everyone wonders what species of animal some of the things we see while diving are, and what the name of particular fishes are. With this dive we will teach you how to identify species, their habits and how to find the common names of a number of animals.

Dive computer

We will provide you with a dive computer and show you how you can safely increase your bottom time. The do’s and don’ts of computer usage are covered along with some advice on selecting a suitable model if you choose to purchase one in the future.

Wreck Adventure Dive

The procedures for diving on wrecks vary considerable from reef diving, mainly because of the potential overhead environment. The Wreck Adventure Dive will highlight the most important safety aspects whilst you experience one of two wrecks around the Gilis.

Intro to Nitrox Adventure Dive

We will explain the advantages of diving with Nitrox and how to calculate your increased bottom time with a dive computer. After the theory you will breathe nitrox for a full dive. Your first dive on mixed gas.

NOTE! If you wanted to get certified as a Nitrox Diver the same time, you could get these two licenses at one go, just by adding some theory and an exam for the extra cost of only 1,100,000 IDR.

    positive review  En vacances à Gili air, sur recommandation d’un ami nous nous sommes rendu à Gili dive pour faire un baptême et nous ne regrettons vraiment pas! La plongée était juste parfaite, en petit groupe nous avons pu bénéficier des explications en français, ce qui nous a permis de profiter au maximum une fois en mer ! Merci encore à l’équipe !

    positive review  There are quite a few dive schools to choose from in Gili Trawangan so choosing one can be a little daunting. I'm so lucky and glad I chose Gili Divers as their staff is top notch. Friendly and beyond knowledgeable, they immediately make you feel welcome and are happy to answer any questions and concerns so as to maximize exactly what your looking for. I was on a tight schedule and were even able to accommodate me so that I could complete my open water certification. I had the pleasure of having Felicia as my instructor and really enjoyed the time learning about the equipment, time in the pool, and especially the dives. She definitely prepared me for any possibilities in the ocean so when my mouth piece fell out mid dive, I didn't even flinch and recovered it just as previously instructed. Really enjoyed my time here on the Island but especially time with Gili Divers, who even have underwater photographers ( thanks Jasper!l who can document your dive experience , I will definitely remember this and can't wait to come back.

    positive review  We did our dive master training in Gili Divers on Air and couldn't be happier. We assisted courses, had theory lessons, pool sessions and lots and lots of great dives. Annie and Greg run the shop with great care and joy, and it was always a pleasure just hanging out in the shop (especially with the cats and later also kittens!!). It didn't feel like going to work but more like being with family, an amazing and wierd diving family! The team has great knowledge about everything from diving equipment and different fish behaviour to how to guide the dive sites according to your level. We also really appreciate their respect for the marine life and the way they pass their knowledge on to others. One of the best things, apart from everything we learned and all the dives we did, is the laughs we shared. We had so many inside jokes that it's actually hard to now function around other people. Reading this, it's easy to understand why this was our third time back, and why we are already planning to return.

    positive review  Wir sind absolut begeistert! Super nettes Team das alle Sprachen spricht und auch schwäbisch versteht 🙂 Für Wünsche und Fragen hat immer jemand ein offenes Ohr und man fühlt sich direkt aufgenommen und wohl. Vor allem was uns wichtig war, dass es keine Massenveranstaltungen sind sondern in kleinen überschaubaren Gruppen abläuft. Mit Phil unseren Guide aus Österreich sind wir seit dem ersten Tauchgang unterwegs und es macht immer wieder Spaß gemeinsam raus zu fahren und abzutauchen. Eine große Besonderheit ist auch das nach Interessen gefragt wird und die jeweiligen Tauchspots dementsprechend ausgewählt werden, wie zb. heute Turtle Heaven 🙂

  • positive review  Eigentlich wollte ich nur einen Test Dive machen und es hat mir so gut gefallen, dass ich ich mich entschlossen habe, doch meine Tauchlizens ( Open Water) zu machen :). Ich war zuvor noch nie tauchen und alle, die es vorhaben oder darüber nachdenken, denen kann ich es nur empfehlen. Es ist ein atemberaubendes Erlebnis! Annie ist eine super Tauchlehrerin, sie hat alles mit Ruhe, Gelassenheit Einfühlungsvermögen und Humor erklärt. Ich hab mich immer gut aufgehoben gefühlt und ihren Fähigkeiten beim tauchen vertraut. Sie liebt das tauchen und genau das lebt sie auch und gibt es an ihre Tauchschüler weiter, was mich sehr beeindruckt hat. Eine super tolle Erfahrung, würde ich jederzeit wieder in dieser Tauchschule machen. Tausend Dank für diese unvergessliche Erfahrung und alles Gute für euch💗! LG, Mareike
