There are three parts of certification: knowledge, skill practice, and open water diving. You can either complete them all locally, while on holiday, or divide them.
A Twinset diver will always be able to access to both tanks from one single regulator as long as the manifold, or the connection between both tanks is open. To carry a twinset for a smaller person might be a challenge on land. It is quite heavy and sidemounted tanks can be carried individually which sometimes makes it easier to access remote areas or steep slopes to access the water.
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.
Television, magazines, and stories from a friend are all good sources of information about the underwater world. Exploring it and getting away from the surface can be exciting. How do we keep exploring? What exactly is technical dive?
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.
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.
A minimum of fitness is required for scuba diving. A physician may be required to approve you before diving if you have any chronic conditions, are taking certain medications, or have had recent surgery.
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.
Technical diving is on the rise and Girls That Scuba HQ was quick to notice it! There were many questions to be answered and nerves to overcome so we decided to seek out Theresia, an Asian tech instructor. She is currently working at Blue Marlin Gili T, Lombok. She provided an introduction course in twin sets, and allowed us to dive into technical diving. Here's her lesson:

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.
Divers who are comfortable with sidemount diving can also enjoy open-water dives. Why? Because sidemount diving is very easy and comfortable.
Being a technical diver requires a lot of training, experience, and passion. The added risks of technical diving are not worth the risk if any one of these is missing.
I arrived just two months ago on Malapascua Island in Philippines. There, I will learn how to become a Tec diver instructor. Since 2012, I've been a Bali recreational instructor. I am eager to improve my diving skills and expand my knowledge. Sidemount PCB was the place where my first experience of technical diving was. Tom West, PADI course director and instructor-trainer for Tec, made me a Certified Tec-50 Diver.
Technical diving (also known as tec diving or tech diving) is non-professional scuba diving that exceeds the agency-specified limits of recreational diving.
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.
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.
