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.
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 next day was technical sidemount. This means that we added our deco 50 and 100 percent oxygen tanks on either side. This can increase your profile underwater. It is important that you keep your tanks as small as possible. The clips can be found on each side. As your tanks become buoyant, you will adjust your tank position to fit the second clip. Here, the goal is to be as efficient as possible. Each few minutes, you switch your breathing between the tanks. By doing this, the pressure in each of the tanks will decrease at roughly the exact same rate. In the event that a tank or regulator fails you will still be able to breathe. It is important to gain experience with any new thing. I spent the next few nights doing deco dives with the sidemount rig. I was buddied with Evolution coowner David Joyce who is a very experienced Tec diver as well as a Trimix instructor. One dive saw us visit the Japanese Mogami Japanese Mogami sank at 164 feet. It was here that I was seduced by old gas masks and uniforms as well as a few bones.
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.
After successful completion, the Tech Diver Level 1 can be started and allows a diver to dive to 51m using appropriate Trimix gas mixes beyond 30m. It is also possible to start Cave Diving Training after the Fundamental Tech Pass.
Sidemount Skills
Although we can teach the SDI course if specifically requested, by default we offer the TDI one. It is possible to take this as a standalone program; however, our students generally combine this with our Apprentice Cave Diver course.
Are you interested to become a Sidemount divers? This is the place for you!
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:
The Sidemount dive setup is slightly different from the backmount, as is the equipment.
Gear – While the gear is fundamentally the same, divers in their introductory tech class (Intro to Tech, Sidemount or CCR Air diluent) will notice some fundamental configuration differences. Instead of 2 second stages on one cylinder they’re split between two, with a separate first stage on each. Gas planning becomes an in-depth thorough process and the harnesses seem to have more chrome.
Sidemount diving has many advantages. You have two tanks with one regulator, a first stage, and SPG. It makes it safer and allows for little air-hogs such as myself to get more air. Sidemount is also very comfortable, as you can quickly put tanks on the water surface and there's no pressure on your back.

Skills (general): The introductory tech diver will practice the use of new equipment to trim and control buoyancy. This helps to build the foundation for efficient diving. Once you have a solid foundation, you can start practicing locomotion or move on to more advanced skills.
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.
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.
Technical diving (also known as tec diving or tech diving) is non-professional scuba diving that exceeds the agency-specified limits of recreational diving.
