Sidemount rigs were created originally for cave diving.
Twinsets on the other hand are two tanks attached to the back of the diver and are usually connected with each other thru a manifold. This means a diver can access to both tanks using a single regulator.
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.
Computer-aided instruction is an integral part of nearly every course we teach. The Why? is simple: eLearning helps get our students in the water sooner and spend more time there. It’s why we include the cost of any applicable eLearning programs — usually a $140 value — in our courses at no extra charge. This translates directly into an extra day of in-water training. The value of that? Priceless.
If you're a Tec diver and want to do sidemount diving, it's important to know how to set up your new rig, adjust it, enter the water with it, and much more.
Our Scotty’s diving center headquarters facility is where all our Tec diving and technical scuba diving lessons are offered. It's located at the Shangri-la Hotel in Mactan. If you don't belong to the Shangri–la hotel, we can either pick you up at home or you can walk in.
Items such as cylinders and primary lights, which my be difficult to travel with, are available for rental. Be sure to alert us if you will need any of these.
International Training is the parent organization of Technical Diving International and Scuba Diving International. They offer both the SDI and TDI versions for their Sidemount Diver course. Both courses are similar. Both courses use the same learning materials (which we also wrote). What's the difference between them?
Mentality - Technical dive is still enjoyable. It's all about looking for cool things. Technical divers can see further and deeper than the sport diver, which allows them to see details that may not be visible to other divers. Technical divers are still fun-focused but also remain focused. Although jokes and laughter are still possible, it is essential to have a serious attitude when planning and executing dives. Every dive comes with risks. If you do not plan, practice skills, and execute your dives properly, these risks will increase.

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.
Sidemount Diver was one of my most challenging courses. This was due to the fact that my instructor Fiona, from Big Blue Tech, a trusted dive center in Koh Takao, included more skills and dives than I needed. My task load was always manageable so we practiced skills repeatedly. This included mask removable, tank removable underwater, out of air drills, and SMB deployment. We also kept our trim.
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.
Mentality: Technical diving is still fun. It's just as much about seeing cool objects, like sport diving. However, technical divers see sights that are longer, deeper, or hidden from sport divers. Technical divers are still a fun and focused group, but they also stay on the right track. There are still plenty of jokes, and there are many laughs. However, dive planning must be executed with seriousness. You are always at risk when you dive, even if you have the right skills and practice.
from 170 to 350 feet
While conventional scuba diving has a recommended maximum depth of 130 feet, technical divers may work at depths ranging from 170 feet to 350 feet, and sometimes even deeper.
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.
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.
