Have you ever wanted to try something new in your diving journey? Are you curious about the idea of having two tanks instead of one, achieving a perfectly horizontal, streamlined trim, and experiencing a dive that feels more natural and unrestricted? If so, the Sidemount Course at Oceans 5 Gili Air is for you.

At Oceans 5, we believe diving is not just about following a routine but about unlocking the full potential of your skills, comfort, and confidence underwater. The sidemount configuration has long been popular with cave divers and technical divers, but in recent years, it has become increasingly popular among recreational divers looking to improve their buoyancy, balance, and overall diving experience.

This course is led by Ary, our resident TDI Technical Diving Instructor and PADI IDC Staff Instructor, who has been diving the waters around Gili Air for more than 10 years. With his experience, passion for teaching, and deep knowledge of the local dive sites, Ary is the perfect guide to introduce you to the world of sidemount diving.


What Is Sidemount Diving?

Sidemount diving is a configuration where the diver carries two smaller tanks (or one if doing a recreational single-tank sidemount) clipped to the sides of the harness rather than one large tank mounted on the back. This setup was originally developed for cave divers to make it easier to squeeze through narrow passages and to improve redundancy in case of equipment failure.

Over time, it became clear that sidemount is not just for caves—it can benefit any diver, in almost any environment. The benefits include:

  • Redundancy & Safety: Two separate tanks mean you have an independent gas supply in case one fails.

  • Streamlined Profile: Tanks are aligned with your body, reducing drag and making finning more efficient.

  • Perfect Trim: Sidemount encourages a naturally horizontal position, ideal for buoyancy control.

  • Comfort: No heavy tank on your back—getting in and out of the water is often easier.

  • Flexibility: Tanks can be clipped on in the water, so no more struggling with heavy gear on land or boats.

Course Structure and What You Will Learn

The sidemount course typically takes 2–3 days, depending on your learning pace and prior experience. Ary keeps class sizes small, ensuring personalized attention and plenty of time to fine-tune your trim, buoyancy, and gas management skills.

1. Classroom & Theory Session

You will begin with an introduction to the philosophy and advantages of sidemount diving. Topics covered include:

  • History and evolution of sidemount diving

  • Equipment configuration and setup

  • Gas management strategies with two independent cylinders

  • Emergency procedures and problem-solving techniques

2. Equipment Workshop

One of the most important parts of sidemount diving is setting up your harness and tanks correctly. Ary will guide you step-by-step through:

  • Harness adjustment for a perfect fit

  • Bungee and hose routing

  • Tank rigging with bolt snaps

  • Weight placement for ideal balance

This workshop ensures that you are completely comfortable with your gear before entering the water.

3. Confined Water Session

Next, you will head to Oceans 5’s training pool, where you will:

  • Practice donning and doffing tanks in the water

  • Master correct body positioning for horizontal trim

  • Learn proper finning techniques to stay streamlined

  • Conduct gas switches and practice emergency drills

This session is your chance to build muscle memory and confidence before heading into open water.

4. Open Water Dives

The highlight of the course! You will complete several dives at some of Gili Air’s best sites, practicing real-world scenarios:

  • Gas management and switches during a dive

  • Buoyancy control while maintaining a horizontal position

  • Team positioning and communication with your buddy

  • Dealing with simulated equipment failures

With Ary by your side, you will be exploring the reefs like never before, noticing how much more balanced and free you feel with the sidemount configuration.


The Advantages of Horizontal Buoyancy

One of the biggest takeaways from the sidemount course is how much better your buoyancy becomes. Because sidemount encourages a horizontal trim, you distribute your weight evenly and use less energy to stay in position. This leads to:

  • Better Air Consumption: Longer, more relaxed dives.

  • Less Silting: Perfect for delicate reef areas—your fins stay clear of the bottom.

  • Improved Safety: You can see your valves and hoses, making it easier to deal with problems.

  • A More Professional Look: Divers often comment that sidemount divers look more “in control” underwater.


Who Should Take the Sidemount Course

The sidemount course is suitable for a variety of divers:

  • Recreational Divers: Looking to improve buoyancy, try something new, and get more comfortable underwater.

  • Photographers & Videographers: The streamlined profile and perfect trim make it easier to get stable shots.

  • Future Technical Divers: Sidemount is an essential foundation for technical diving courses like decompression procedures or cave diving.

  • Older Divers or Those with Back Problems: No more heavy tank on your spine—gear can be clipped on in the water for maximum comfort.


Dive Sites You May Visit During the Course

Learning sidemount at Oceans 5 means you will have access to a range of exciting dive sites around Gili Air:

  • Hans Reef: Known for sandy bottoms perfect for practicing trim, as well as macro life like frogfish and pipefish.

  • Bounty Wreck: A great site to experience sidemount’s advantage in exploring tight areas around a wreck.

  • Shark Point: For a slightly more adventurous dive where you may spot reef sharks, turtles, and big schools of fish.

  • Secret Reef & Mentigi Bay: Calm conditions make these sites ideal for practicing gas switches and buoyancy drills.
