How long will Titanic last underwater

Although I have not yet mastered the art of Sidemount diving, I am proud to be a Sidemount diver.
If you plan to go sidemount, particularly if you are a tec diver already, you will need to learn about your new rig. How to adjust it, how it can be used to enter the water, and more.
You might consider continuing to Tec Sidemount Diver, where you will learn additional skills that are specific to tec diving in sidemount like switching deco cylinders and staging.
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.
The sidemount rig was originally invented for cave diving as it allows the diver to pass thru cracks and restrictions (tiny holes) easier than the classic back mount rig.

I was a bit numb after my initial pool sessions. I was strapped into the twin tanks, trying to conduct valve drills. But, the Tec 40-45 and 50 courses helped me to feel more comfortable and my skills began to improve. By the end of the course, I was enjoying myself. It's about taking your diving skills, buoyancy and awareness up to the next level. This is what Tec diving offers. This is a great feeling. Knowing you're capable in managing life-threatening emergency situations at depth without the need to ascend to the surface (dues decompression requirements), is an amazing feeling. It's very satisfying to execute your dive program with military precision.
There is a wide variety of equipment that is used by technical divers the biggest impact on the decision is the environment a diver is exposed to. Many cave divers prefer to use Sidemount which means, independent single tanks are mount to the side of the divers’ body and attached by clips on a D-Ring on the waist band on the harness and on the shoulder. This allows the diver to detach and don tanks to fit thru tiny restrictions and have a lower overall profile to go to places unreachable for divers who chose backmount. During multiple trips, additional tanks can be placed in a cave or a wreck to allow the diver deeper penetration dives and to pick up tanks when leaving the cave or wreck.
Gear - Although the gear is the same, divers who are enrolled in an introductory tech class (Intro Tech, Sidemount, or CCR Air Diluent) will notice fundamental differences in the configuration. Instead of having 2 second stages per cylinder, they are split into two with each stage having a separate first. The gas planning process becomes more detailed and the harnesses have more chrome.
Nowadays diving sidemount became popular even in open water as you get more streamlined than having a tank on your back, it is not hurting your back, and you can get a lot of fun as it is extremely comfortable to dive sidemount.
New gear means new techniques. If you are able to dive sidemount, it is easy to acquire new skills.

To dive beyond 130ft, decompression divers should add some Helium to their cylinders. This will allow them to enter the realm of the seldom seen. Sometimes, the reefs and wrecks they visit are visited less often per year than astronauts to orbit the moon.
Academics - Technical courses have similar academic requirements to other classes. Students will conduct some self-study and present their findings to their instructor. A technical course requires that you plan your dives in advance. This is a crucial step to ensure a safe and successful dive. The gas management discussion in overhead and deep diving is more complex than what most divers are used too. A computer program can be used to calculate gas volumes and reserves.
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).
