Sidemount diving is also very popular, even in open water. Why? Because diving sidemount is very comfortable and easy to learn.

Your Sidemount rig also includes clips and tank bands. These clips will attach to your harness. Again, their location is crucial for the positioning of your tanks.

Decompression divers employ oxygen mixtures of all kinds to extend their time looking at wrecks and reefs on the ocean floor. While the sport diver may get two 15 minute bottom time dives at 100ft the decompression diver can cruise around for 60 minutes or more, getting the most bang for their buck.

Next, it was time to do technical sidemount. This involves adding our deco 50-percent and 100-percent oxygen tanks on each side. You will have a higher profile underwater, so it is important to keep the tanks as close to your body as possible. There are two clips at each side of the waist. You adjust the tank position by inhaling down your tanks. This is where simplicity is key. You also need to switch between tanks every few minutes. This ensures that the pressure in each tank is at the same level, so even if one tank or regulator fails, there will still be gas for you to breathe. Building up experience is the key to comfort, enjoyment and success with new technologies. The next few days were spent doing sidemount dives, budding up with Evolution coowner David Joyce, a highly experienced Tec diver and Trimix instructor. One dive took us to the Japanese Mogami Wreck at 164 feet. I was captivated by the old gas masks, uniforms, and bones that we found.

Sidemount Configuration

All our Tec diving lessons (open circuit or closed circuit rebreather) and technical scuba diving classes are given at our Scotty's dive center headquarters facility, located in the Shangri-la hotel in Mactan, Cebu province. If you are not a guest of the Shangri-la hotel, you can always walk in, or we can pick you up at your hotel.

Sidemount divers usually use two tanks. However, it is possible to use one tank as a standard. I was also told that you can use one tank for deco diving.

This course will require the same equipment, as your goal is to learn the operation and setup of the equipment you will use during your cave diving or tech diver training. This includes:

TDI is an American tech diving organization that was found in 1994 and has instructors all around the world. The prerequisite to start technical diving with a TDI instructor are the Advanced Open Water certification of any organization, Nitrox certified and a minimum of 25 dives. The first technical diving courses are TDI Sidemount (within No deco limits) and Advanced Nitrox and Decompression Procedures allowing to dive to 45m, using oxygen mixes up to 100% of oxygen and doing staged decompression stops. The course contents include theory, pool work, and a minimum of 6 dives depending on your level of comfort in the water in order to be able to complete all open water requirements safely and efficiently and to understand planning and preparation of a technical dive.

Your Sidemount BCD is a harness with a bladder and a somewhat intricate system of sliding D-rings, bungee cords, and clips. Their position and fit are crucial for your tank position and trim later in the water and your instructor will probably spend quite a bit of time to get them just right.

Gear – While the gear is fundamentally identical, divers in their intro tech class (Intro, Tech, Sidemount or the CCR-Air diluent), may notice some fundamental configuration changes. They now have two second stages, each with a separate start stage. Gas planning becomes a detailed, thorough process. The harnesses also have more chrome.

I will admit my Sidemount Diver course was probably one of the most challenging courses I have ever done. Mind you, this was mainly because my trusted dive center in Koh Tao, Big Blue Tech, and my instructor Fiona included a lot more skills and dives as part of my course than required. While always making sure that my task load was manageable we practiced skills over and over again and included things like mask removable, tank removable underwater, SMB deployment, out of air drills, and many more all while staying (or at least trying to) in perfect trim.

This course will teach you how to set up and operate the equipment that you will use in your training as a cave diver or tech diver. This includes:

Depending on the environment and type of diving each configuration has its advantage and disadvantage. Diving in caves or wrecks the preferred way to dive for sure is either Sidemount or rebreathers. There is also an option for a Sidemount rebreather which makes the diver more streamlined to fit through narrow restrictions. Sidemount also gives the diver the advantage to leave tanks behind that will be picked up upon exiting the cave or wreck. To fit through narrow bedding planes unclipping the tanks makes the profile of the diver even smaller and places that are not available to a backmounted twinset diver become accessible.

Frequently Asked Questions

5-6 days
Rebreather training classes are typically 5-6 days long, but can be longer depending on a variety of factors such as the training agency, your local conditions, your instructor, and your ability to meet the class standards.

- Increased Bottom Time A Closed Circuit diver is not concerned with running out of gas because they are only limited by decompression. This can also be reduced by selecting an oxygen partial pressure that provides the diver with virtually limitless bottom times in 60 feet or less of water.

2-3 hours
Even with small cylinders, you can usually dive for 2-3 hours (rebreathers typically have two 2/3l cylinders or one 3/5l cylinder).
