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.
‘Caverns Measureless to Men’ by Sheck Exley, one of the pioneers of cave diving in Florida, USA. He also wore ‘Basic Cave Diving: A Blueprint for Survival’ which studies many cave diving accidents.
To make dives beyond 130ft, decompression divers will add Helium to the cylinders. Then they can explore the realm of the uncommon. Their experiences at wrecks and reefs are often less frequent than those of astronauts who visit the moon.
Skills (specific): Throughout tech programs, the dive skills specific to that category are practiced until they become flawless. Line skills and navigation are perfected for overhead diving. Decompression divers can execute stops and manage gas without blinking an ear. Rebreather divers take great care in building, testing and disassembling their equipment to ensure its optimal functionality. The first level of certification lays the foundation for each course, with further training as necessary. Each step takes you deeper, or makes these skills more difficult. It is a way to become a better diver.
Don't worry if you are worried about how everything will fit together. You will learn how to set up your Sidemount equipment. Also, how to measure and adjust your bungees and clips so your tanks stay in line next to your legs. Your instructor will guide you through all this!
Sidemount cylinder mounting was developed for cave diving. They have been more popular in technical diving ever since. They are able to seperate the dual cylinders and mount them on either end of the diver's body. While this prevents the diver from breathing from one cylinder in case of a failure of the regulator, it allows them to have easier access to the valves. Sidemount diving provides a diver with a more horizontal profile but a smaller vertical one.
The benefits of rebreathers include the ability to extend your diving time by avoiding large cylinders and instead recycling the gas exhaled from the diver. They also scrub the CO2 out of the air and inject prescriptive amounts gas from smaller cylinders. This can significantly increase your dive time, especially for deep dives. The configuration of the rebreathers will determine the shape they create. They can be either sidemounted or back.
I have just arrived in Malapascua Island on the Philippines. Over the next two months, I will work my way to becoming a Tec dive instructor. I've been a recreational dive instructor in Bali for two years. I would like to add more experience to my portfolio. Sidemount PCB was my first experience with technical diving. Tom West (PADI instructor-trainer) made me a certified Tec-50 diver.

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 rigs were initially designed for cave diving. It allows divers to pass through small cracks and restrictions (tiny hole) much more easily than the traditional back mount rig.
Your Sidemount BCD harness is made up of a bladder, sliding D-rings and bungee cords. Your tank position and trim will depend on their fit. Your instructor may spend a lot of time getting them right.
You will also learn how to use Sidemount regulators. Usually, you will have one regulator on a long hose as well as one regulator on a short hose with a necklace. Unlike your normal regs, Sidemount regs are also marked so you can easily distinguish which tank you are breathing from. During my training, this included a swivel joint for my short hose regulator. In addition, you will have 2 SPGs – one for each first stage.
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).
Have a PADI Deep Specialty Instructor certification or have completed a PADI Deep Specialty Instructor course. Have at least 100 logged dives, including at least 20 enriched air dives, 25 dives deeper than 18 meters/60 feet, and 15 dives deeper than 30 meters/100 feet. You can become a Tec 45 diver.
According to experts, approximately 40% of technical divers enroll in additional education and training programs. This yields a reasonable estimate of approximately 160,000 active technical divers worldwide.
