Technical diving can be defined as being exposed to a ceiling that prevents a diver from ascending to the surface during a dive. This could be caused by a ceiling (in terms of a cave, a wreck, etc.) or a virtual ceiling that is created by a decompression duty. To avoid decompression sickness, it is necessary to perform mandatory decompression stops on ascent if you exceed the NDL. This requires special equipment such as a Twinset or Sidemount. Special equipment such as Twinsets and Sidemounts, gas mixtures with special properties, and additional training are required to be able perform the stops on ascent accurately to maximize Nitrogen off-gassing.
You will also find tank bands, clips and possibly some additional bungees in your Sidemount rig to store your regs. Your harness will have clips that attach to it. Their position is critical for your tanks.
The initial pool sessions were tough; I felt like an open-water diver again, strapped into the twin tanks and trying to conduct valve drills. But as we progressed through the Tec 40, 45 and 50 courses, new skills started to come naturally, and by the end of the course I was enjoying myself. The satisfaction in Tec diving comes from taking your dive skills, buoyancy and awareness to the next level. Knowing that you’re capable of managing life-threatening emergencies at depth, and without the option to ascend straight to the surface (due to decompression requirements) is quite a buzz. And it’s satisfying to execute your dive plan with military precision.
While technical diving is still for fun they aren’t for people wanting to go deeper, just because. There is a higher risk associated with cave and decompression diving. This risk is mitigated, in part, by thorough dive planning and training. As such, divers doing these dives are held towards a higher standard. It will take practice to become a technical diver. No amount of research and reading can supplement that in water time. Divers will notice that the minimum standards are often exceeded during training courses and individual technical instructors often do this. Technical training teaches a diver redundancy so that problems can be successfully solved 1500ft inside a flooded cave and an exit to the surface can be executed. While that sounds complex and scary it’s a necessary aspect of diving in that environment. Technical training is not only challenging but it’s fun and at the end of it the diver has a golden ticket to see parts of the world that are totally closed off to other people.
Sidemount PCB is available to help you and your physician with questions about medical fitness for diving.
Scuba diving sidemount is becoming more popular than ever in open water. You are more streamlined than having to carry a tank around your back.
However it is important at greater depths to decrease effort and achieve maximum performance to avoid overexertion and CO2 buildup. CO2 is the trigger for our breathing reflex, so the more CO2 we build up the more we will feel the urge to breathe. This means in the same amount of time we will pump more gas through our lungs and we take in more gas in the same amount of time.
Technical diving was something that I never had an interest in at first. I remember laughing at the Tec divers and wondering why anyone would need more equipment. I love the feeling you get when you are close to nature. Tom had a reputation for being an inspirational teacher. It seemed to me that I should at least try.
The goal of this course is to teach you the basics of how to use the equipment in your cave or tech diver training. You will also need the same equipment for the course. This includes:
Despite the gear choice the entry level tech diver will be taught to streamline their equipment to prevent dangling items and drag. This ensures a maximized profile for efficient propulsion and awareness.
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!
Television, magazines or stories from a close friend can all be used to explore the underwater world. It doesn't really matter which source you use, it is still exciting and very enticing. So what can we do to continue exploring? What is technical diving?
Backmounted doubles came into use in part because of the problems with backmounted independents and single orifice doubles, neither of which are as common in modern diving. Independents are two cylinders strapped to one’s back with independent regulators on each one. If a 1st stage was to fail the diver was down to one cylinder. Single orifice doubles were two cylinders linked together with a valve, and one 1st stage regulator. If a first stage failed on a single orifice doubles set all the gas would be lost. The isolated manifold doubles used today eliminate both of those problems. Each cylinder can be worked independently, but the diver can also breathe gas from both cylinders out of one regulator. This form of doubles is typically held together with metal bands and the valves are linked with an isolation manifold, allowing the two to be separate if needed. Backmounted doubles diving is similar to regular single cylinder backmount, offering a profile that is vertically the same.
The Sidemount diving setup is a little different from the setup when diving backmount and so is the equipment.
