Technical diving was something I didn't initially like to do. I clearly remember chuckling at the Tec divers that I saw and wondering why anyone would want more equipment underwater. The feeling of being close to nature and the freedom it can give you is something I love. Tom was an inspiring teacher and it seemed right to try, as I was working at a dive shop that offered Tec courses.
Dive sidemount has become a popular sport in open waters. While it looks more sleek than having a tank strapped to your back, it doesn't hurt your back.
And then there are the rebreathers…a rebreather is a machine that recycles exhaled gas and is the preferred method for ‘very’ deep dives in order to use the gas carried more efficiently. In this case the exhaled gas is going thru a canister filled with a chemical which is called Sofnolime or scrubber to remove CO2 from the breathing loop and the remaining gas will be inhaled again by the diver. Metabolised oxygen is replaced into the loop to keep the oxygen content in the divers’ body at the desired pressure.
We do not issue certification cards unless they are earned. The mere fact that you have taken part in a training course does not make you certified. There may be multiple certification agencies that offer certification cards for cave courses. C-cards typically cost $30 each depending on the agency. You can ask your instructor more.
There are three parts to certification: knowledge development, skill practice and open water dives. You can complete all three parts locally, on holiday, or split between the two.
I can't recall when or why it was that I decided to take the Sidemount course. Like most of my diving decisions it was just a matter of "oh, that looks cool", and I was willing to give it a try. Sidemount would have been a valuable certification that I could use for future training. Sidemount certification would also be helpful if I wanted to go cave diving.
These cards are only issued to those who have earned them. Participating in a course is not a guarantee of certification. Certification cards may be offered by multiple agencies for cave courses. C-cards cost $30 to $30 per card, depending on the agency. Ask your instructor for more information.
Your Sidemount BCD is a harness with a bladder. There are also a number of sliding D-rings, zips, and bungee ropes. It is important that they are in the right place and fit for your tank.
Sidemount regulators can also be used. One regulator will be on a long length hose, while one regulator will be on a shorter one with a necklace. Sidemount regs have a marked design, which makes it easy to identify the tank you are in. This also included a swivel connector for my short-hose regulator. Two SPGs will be provided - one for each stage.
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.
While I still haven’t perfected this art, I am proud that after 20 Sidemount divers I can call myself a Sidemount Diver. It is the most comfortable way of diving!
At first I was not interested in technical diving. I vividly remember chuckling at the Tec divers who I saw and wondering what made them want to take more equipment. I love the sense that you can be close to nature while feeling free and connected. Tom was a well-respected teacher. I felt it only right to give him a try as I was working in a dive shop offering Tec courses.
Are you interested in becoming a Sidemount diver. This post will explain everything you need to know about becoming a Sidemount diver.
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.
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.
