Tec 40 is the first step to start the TecRec program with Padi. The prerequisites are Advanced Open Water and Deep Diver certifications as well as Nitrox. In addition to that, before starting the course a minimum of 10 Nitrox dives have to be proved. The certification allows divers to dive to 40m doing limited decompression using gas mixes up to 50% of oxygen. The Tec 40 is also the prerequisite to continue with Padi Tec 45 which allows to do unlimited decompression time as long as it is carefully planned. The next step will be Tec 50 that enhances the allowable depth to 50m.
There are three components to certification: skill practice, knowledge development and open water diving. All three parts can be completed locally or on vacation, or you can split them.
Rebreathers can increase your diving skills by using smaller cylinders. This can significantly increase the dive duration, especially when used for deeper dives. Rebreathers can be mounted sideways or back. It all depends on how they are configured.
The benefits of rebreathers include the ability to extend your diving time by avoiding large cylinders and instead recycling the gas exhaled from the diver. They also scrub the CO2 out of the air and inject prescriptive amounts gas from smaller cylinders. This can significantly increase your dive time, especially for deep dives. The configuration of the rebreathers will determine the shape they create. They can be either sidemounted or back.
Sidemount regulators will be taught. Asidemount regulators can be used on both long and short hoses. Sidemount regs are marked differently to normal regs. This allows you to easily identify the tank that you are currently breathing from. In my training, I was given a swivel elbow to use as a regulator for my short tube. There will be 2 SPGs available - one each for each stage.

Learn our SSI technical sidemount diver course and get the opportunity to dive with four+ tanks (cylinders) for extended dives. The technical sidemount diver course is an excellent way to get yourself into technical diving as it will train you to handle multiple cylinders on a single dive. Learn also on configuring your sidemount gear and setting up a tec sidemount harness as well as adjusting the sling tanks (cylinders) on your body.
Some other wreck diving books are ‘The Last Dive’ by Bernie Chowdhury about father and son who are crazy about wrecks and eventually find their destiny on a German U-boat.
I will admit my Sidemount Diver course was probably one of the most challenging courses I have ever done. Mind you, this was mainly because my trusted dive center in Koh Tao, Big Blue Tech, and my instructor Fiona included a lot more skills and dives as part of my course than required. While always making sure that my task load was manageable we practiced skills over and over again and included things like mask removable, tank removable underwater, SMB deployment, out of air drills, and many more all while staying (or at least trying to) in perfect trim.
Specific Skills - These are the skills required to perform specific types of diving. Navigation and line skills are developed until they are effortless for overhead diving. Decompression divers have the ability to execute stops and gas management plans without a blink of an eye. Rebreather divers test, build and then disassemble their equipment meticulously to ensure it works properly. Each course requires skills that are established at the initial level. Then, it is possible to move on to higher levels. Each step further or hones these skills, and adds more challenges to make a diver well-rounded and knowledgeable.
It is possible to rent items such as primary light bulbs and cylinders which can be cumbersome to carry. You should let us know if any of these are required.
You don't need to worry about how all this will work. The course includes learning how to set-up your Sidemount equipment, as well as how to measure and adjust clips and bungees so that your tanks are in perfect trim. You will have your instructor to assist you in all aspects.
Divers who decompression dive use oxygen mixtures of every kind to prolong their time on the seafloor looking for wrecks and corals. The sport diver might only get two dives at 100ft, but a decompression diver can cruise for up to 60 minutes and still get the best bang for their buck.

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.
To register for the PADI Advanced Rebreather Diver course, you must first: You must be a PADI Open Water Diver, but you must also be a PADI Advanced Open Water Diver to become a PADI Advanced Rebreather Diver. Have at least 30 dives under your belt.
- 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.
