Your Sidemount BCD is a harness with a bladder and a somewhat intricate system of sliding D-rings, bungee cords, and clips. Their position and fit are crucial for your tank position and trim later in the water and your instructor will probably spend quite a bit of time to get them just right.
The following options are available for those looking for diving classes alternatives and lessons, as well as information on the best next steps in their education.
While technical diving is still fun, it's not for people who wish to go deeper. Cave and decompression dives carry more risk. The best way to reduce the risk is to plan your dives and train well. This is why divers who take these dives must be held to a higher standard. It takes practice to become a competent diver. There is no substitute for the practice and time in the water. Divers will be able to see that the minimum standards are frequently exceeded during training courses. Individual technical instructors sometimes do this. Technical training teaches divers how to redundancy. It enables them to solve problems at 1500 feet inside a cave. It's not easy and it's scary, but it's an important aspect of diving within that environment. Technical training can be challenging, but it can also be fun. At the end of it, the diver will have the ability to see areas that are completely closed off to the rest of the world.

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.
Academics – The academic portions of a technical course are very similar to any other scuba class. Students will do some self study and bring the new knowledge to a discussion with their instructor. The dive planning aspects for a technical course are significantly extended from what most individuals are used to but a vital part of executing a successful dive. In overhead and decompression diving, the gas management portions of the planning discussion will take longer than most divers are used to. They even utilize a computer program to calculate their gas volumes and reserves required for the dive.
Backmounted doubles were created in response to problems with single orifice and backmounted independences. Independents consist of two cylinders, each with its own regulator. The diver could only use one cylinder if a first stage failed. Single orifice duals consisted of two cylinders linked by a valve. One regulator was used for the first stage. The gas would not be released if the first stage failed due to a failure of one orifice doubles. Both of these problems have been eliminated by today's isolated manifold duplicates. Each cylinder is capable of being worked separately, but the diver can use one regulator to allow him or her to inhale gas directly from both cylinders. This type of doubles is usually held together using metal bands. Additionally, the valves are linked by an isolation manifold which allows the two to be separated as needed. Backmounted doubles diving looks similar to regular single cylinder backmounts, but it has a profile that is vertically identical.
I just arrived on Malapascua Island (Philippines) and will soon be working my path to becoming a Tec instructor. I've been working as a recreational instructor at Bali for the past two-years and would love to grow my professional experience. Sidemount PCB gave me my first taste in technical diving. Tom West was the PADI course director, and Tec instructor-trainer. He made me into a PADI Tec-50 diver.

Technical diving can be defined as being exposed to a ceiling that prevents a diver from ascending to the surface during a dive. This could be caused by a ceiling (in terms of a cave, a wreck, etc.) or a virtual ceiling that is created by a decompression duty. To avoid decompression sickness, it is necessary to perform mandatory decompression stops on ascent if you exceed the NDL. This requires special equipment such as a Twinset or Sidemount. Special equipment such as Twinsets and Sidemounts, gas mixtures with special properties, and additional training are required to be able perform the stops on ascent accurately to maximize Nitrogen off-gassing.
It's normal to be anxious about how it will all work out. Your instructor will assist you with everything!
Sidemount diving offers additional air sources, as you can dive with two tanks, each one with an SPG regulator and a first stage. Sidemount diving is safer and provides little air-hogs, like me, with more air. Sidemount diving is extremely comfortable. You can put tanks on the surface, and there is no pressure on your stomach.
To dive, you must have a minimum of fitness and good health. Before diving, you may need to be cleared by a doctor if your health is not in good condition.
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.
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.
Technical diving (also known as tec diving or tech diving) is non-professional scuba diving that exceeds the agency-specified limits of recreational diving.
- Increased Bottom Time A Closed Circuit diver is not concerned with running out of gas because they are only limited by decompression. This can also be reduced by selecting an oxygen partial pressure that provides the diver with virtually limitless bottom times in 60 feet or less of water.
