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.

What Do You Need To Become A Scuba Diving InstructorNew gear means new techniques. Scuba diving sidemount is easy if you have the right skills.
Continue on to the Tec Sidemount Diver program. Here you'll learn additional skills, such switching deco cylinders, and stage and switch deco cylinders.
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.
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.
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.
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.

Sidemount diving is a great option, especially for those who are already tec divers. You will need to learn how to adjust your rig, how you can enter the water with it (yes, it is different, but it is more relaxed).
The very general definition of technical diving is to be exposed to a ceiling that does not allow a diver to ascend to the surface at any moment of the dive. This might be due to a real ceiling, in terms of a cave or a wreck, or a virtual ceiling created by a decompression obligation. In this case, by exceeding the NDL’s, mandatory decompression stops have to be performed on ascent in order to avoid any case of decompression sickness. In most cases this requires the use of special equipment, e.g. Twinsets or Sidemount, special gas mixes and of course additional training to be able to perform those stops accurately on ascent to optimize off-gassing of Nitrogen.
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.
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.
To begin a technical diving course, you must have completed the following prerequisites: a PADI Advanced Open Water Diver certificate or equivalent, a PADI Enriched Air Diver certificate or equivalent, and a PADI Deep Diver certificate or proof of at least 10 dives to 30 metres/100 feet.
