How To Become A Sidemount Technical Scuba Diver Life Expeditions

Diving Instructor

There is a wide variety of equipment that is used by technical divers the biggest impact on the decision is the environment a diver is exposed to. Many cave divers prefer to use Sidemount which means, independent single tanks are mount to the side of the divers’ body and attached by clips on a D-Ring on the waist band on the harness and on the shoulder. This allows the diver to detach and don tanks to fit thru tiny restrictions and have a lower overall profile to go to places unreachable for divers who chose backmount. During multiple trips, additional tanks can be placed in a cave or a wreck to allow the diver deeper penetration dives and to pick up tanks when leaving the cave or wreck.

Overhead diving professionals are allowed to use cave passages that were formed by millions of years worth of water erosion. They can be found thousands of feet away from the entrance. These sites are a treasure trove of beauty and tranquility, which was only possible because of the time it took to form them.

Backmounted doubles were created in response to problems with single orifice and backmounted independences. Independents consist of two cylinders, each with its own regulator. The diver could only use one cylinder if a first stage failed. Single orifice duals consisted of two cylinders linked by a valve. One regulator was used for the first stage. The gas would not be released if the first stage failed due to a failure of one orifice doubles. Both of these problems have been eliminated by today's isolated manifold duplicates. Each cylinder is capable of being worked separately, but the diver can use one regulator to allow him or her to inhale gas directly from both cylinders. This type of doubles is usually held together using metal bands. Additionally, the valves are linked by an isolation manifold which allows the two to be separated as needed. Backmounted doubles diving looks similar to regular single cylinder backmounts, but it has a profile that is vertically identical.

Sidemount diving originated in cave diving, but it has made its way to recreational and non-overhead diving in recent years. You will now wear your tanks side-by-side, instead of having one or two tanks attached to your back. You can attach the tanks to your Sidemount BCD using clips or bungee cords. This allows for extreme flexibility. This flexibility was initially what allowed cave divers to remove their tanks underwater in order to fit into narrow spaces and make their profile smaller.

The technical sidemount was completed the next day. This involved adding our 50-percent oxygen tank and 100 percent oxygen tanks to either side. This will increase your profile underwater. You must ensure that the tanks are as slim as possible. A couple of clips are located on either side of your waist. When your tanks become positively buoyant and you inhale, adjust the clip to match your tank position. It is important to keep your breathing as smooth as possible. Your breathing will change from one tank to another every few minutes. The pressure in each tank will drop at approximately the same rate. If a regulator or tank fails, you will still have gas to breath. Comfort and enjoyment can only be achieved by gaining experience. I spent the next few day doing deco dives using the sidemount rig with Evolution co-owner David Joyce, a Trimix instructor and Tec diver. We visited the Japanese Mogami wreck at 164ft, where I was charmed by the pieces of old gas masks and uniforms.

Sidemount diving provides an independent air source. Two tanks are used, each with their own regulators and first stage, SPG. This makes it much safer and gives little air-hogs (like me) a lot more oxygen. Sidemount's tanks can be easily accessed from the surface. There is no pressure on the back.

Divers using decompression oxygen mix all types can extend their time looking at wrecks or reefs on the oceanfloor. The sport diver may be limited to two short dives at 100ft. A decompression diver can cruise the seas for 60 minutes or longer, getting more bang for his buck.

While I still haven’t mastered this art quite yet, I am proud to say that after 20 Sidemount dives I am excited to call myself a Sidemount diver and think it is the most comfortable way to dive!

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:

Skills (general) – The introductory tech diver will practice their trim and buoyancy with the new equipment configuration. This builds the foundation of efficient diving. Once the foundation is there the student can practice locomotion and move on to more advanced skill practice.

Sidemount diving is a great option, especially for those who are already tec divers. You will need to learn how to adjust your rig, how you can enter the water with it (yes, it is different, but it is more relaxed).

Frequently Asked Questions

To begin a technical diving course, you must have completed the following prerequisites: a PADI Advanced Open Water Diver certificate or equivalent, a PADI Enriched Air Diver certificate or equivalent, and a PADI Deep Diver certificate or proof of at least 10 dives to 30 metres/100 feet.
 

The depth range of oxygen rebreathers (simple closed circuit) is limited to approximately 6 m, beyond which the risk of acute oxygen toxicity rises to unacceptable levels very quickly.

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).
