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.

Technical diving was something that I never had an interest in at first. I remember laughing at the Tec divers and wondering why anyone would need more equipment. I love the feeling you get when you are close to nature. Tom had a reputation for being an inspirational teacher. It seemed to me that I should at least try.

Sidemount can provide a number of benefits for any diver, but is especially well suited for cave diving. (It was, after all, cave divers who invented sidemount.) Among these benefits:

My first courses were sidemount and technical sidemount. Sidemount diving, as the name suggests, involves placing your tank my hands and knuckles were covered in cuts by the end of the session. The idea is that you can unclip the tanks and put them out in front of you, Superman style, thus streamlining yourself. After some sizing adjustments to the harness, the afternoon dive went much more smoothly. I was now comfortably unclipping and ‘Superman-ing’ with the tanks. Compared to having doubles on your back, sidemount offers an incredible level of freedom. Matt set up obstacle courses and we were soon flying around them with tanks held out front, barrel-rolling and even swimming upside down.

The shift from backmounted doubles into sidemount has been one of the biggest changes in the equipment that cave divers have used since the turn of the century. A large number of cave divers sidemount. Additionally, there may be more sidemount cave divers than open-circuit backmount cave divers.

Sidemount and technical were my first courses. Sidemount diving involves placing your tanks in your hands. I was so numb that my fingers and knuckles had been cut by the end. The idea is to take the tanks off of your hands and let them flow out in front. After making adjustments to the harness's size, the afternoon dive went much easier. I was now able to unclip the harness and 'Superman' with the tanks. Sidemount provides an amazing degree of freedom. Matt installed obstacle courses, and we soon found ourselves flying around them while holding tanks at our feet. We also tried barrel-rolling and swimming upside down.

Different depths require the use of different gas mixes. The maximum partial pressure of oxygen a diver wants to dive at is 1.4 which is reached on air at 56m. Due to the water pressure the pressure of each individual gas increases and therefore we need to use appropriate mixes if we choose to go deeper. In general, the more oxygen a gas mix has the less deep we can go. A tech diver will use low oxygen mixes at depth and high oxygen mixes coming up shallower to off-gas Nitrogen faster and decrease the mandatory decompression time overall.

Technical divers explore reefs and wrecks at depths below the 40 meter/130-foot recreational limit. With specialized training, they can explore underwater caves and other places well beyond the reach of mainstream recreational diving.

Divers must maintain a minimum level fitness and health. Some conditions such as chronic illness, recent surgery or medication may make it necessary to obtain written permission before you can dive.

If you're not ready to try diving locally, but want to support your local dive shop, you can complete eLearning and coursework near home, then complete your training dives while traveling. Contact your local PADI Dive Center to ask about a referral.

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.

Frequently Asked Questions

- 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.

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).

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.
