Gear - While all gear is identical, divers in their introductory tech classes (Intro To Tech, Sidemount and CCR Air diluent), will notice some fundamental differences in their configurations. Instead of being split into 2 stages on a single cylinder, the second stages are divided up between two with a separate stage on each. Gas planning becomes more complex and the harnesses are more chrome.
Due to the issues with single-orifice doubles or backmounted independents (which are not as common in modern diving), backmounted doubles were invented. Independents are two independent cylinders attached to one's back, with independent regulators for each. One cylinder was sufficient to take care of a failed 1st Stage. Single orifice duplicates were two cylinders linked with a valve and one regulator. A single orifice doubles set would cause all gas to be lost if a first stage fails. These problems can be eliminated with the modern isolated manifolds. Each cylinder can work independently but divers can also inhale gas from both of them through one regulator. These doubles are typically held together with metal bands. The valves can also be linked with an isolation device, which allows them to be seperated if required. Backmounted doubles diving offers a profile that's vertically identical to regular single-cylinder backmount.
In addition, your Sidemount rig includes tank bands, clips, and probably some more bungees to stow away your regs nicely. The clips will be connected to your harness and again, their position is important for the position of your tanks.
The Sidemount diving setup differs from that used for backmount diving.
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.
You can do eLearning and coursework at home to help support local dive shops. Then, travel to complete your training dives. For a referral, contact your local PADI Dive Center.
Sidemount can be a boon for all divers, but it's especially useful for cave diving. (It was actually cave divers that invented sidemount. These are some of the benefits:
At first, technical diving was not something that interested me. I can clearly recall chuckling to my self at the Tec divers I observed, and wondering why anyone would want to have more equipment under water. I love the feeling of freedom and closeness to nature that can envelope you in "the quiet world". Tom was a respected teacher who I felt it was important to share my experience in Tec courses with.
The Sidemount dive setup is slightly different from the backmount, as is the equipment.
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.
It is becoming more popular to do technical diving and we were immediately drawn to it at Girls that ScubaHQ! We had many questions and nerves, so we went to Theresia Gollner, who is working at Blue Marlin Gili T in Lombok. We were given an introduction to twin sets by her and then she let us in on the amazing world of technical diving. Here are the lessons she gave us:
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).
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.
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.
