Skills (generally speaking) - The introductory technical diver will practice their trimming and buoyancy using new equipment. This builds the foundation for efficient diving. Once the foundation is in place, students can start to practice locomotion and then move on with more advanced skills.
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.
Overhead divers who have been trained in overhead diving are entitled to cave passages created over millions of year of water erosion. These passages can stretch thousands of yards from the entrance. They offer tranquility and beauty that is unmatched by the amazing time they took to form.

If you are not ready to dive locally, but wish to support your local dive center, you can complete eLearning courses and coursework close to home. You can then travel to complete your training dives. Ask your local PADI Dive Center for a referral.
Skills (general) – The introductory tech diver will practice their trim and buoyancy with the new equipment configuration. This builds the foundation of efficient diving. Once the foundation is there the student can practice locomotion and move on to more advanced skill practice.
You will also learn how to use Sidemount regulators. Usually, you will have one regulator on a long hose as well as one regulator on a short hose with a necklace. Unlike your normal regs, Sidemount regs are also marked so you can easily distinguish which tank you are breathing from. During my training, this included a swivel joint for my short hose regulator. In addition, you will have 2 SPGs – one for each first stage.
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.
Our Scotty's headquarters facility for diving, Scotty's Scotty's, is located in Mactan, Cebu. We offer Tec diving lessons (open-circuit or closed-circuit rebreather) as well as technical scuba diving classes. You can walk in if you're not a Shangri-la guest or we can pick your up at your hotel.

Sidemount cylinder mounting was developed for cave diving. They have been more popular in technical diving ever since. They are able to seperate the dual cylinders and mount them on either end of the diver's body. While this prevents the diver from breathing from one cylinder in case of a failure of the regulator, it allows them to have easier access to the valves. Sidemount diving provides a diver with a more horizontal profile but a smaller vertical one.
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.
Your Sidemount rig also includes clips and tank bands. These clips will attach to your harness. Again, their location is crucial for the positioning of your tanks.
While technical diving is still for fun they aren’t for people wanting to go deeper, just because. There is a higher risk associated with cave and decompression diving. This risk is mitigated, in part, by thorough dive planning and training. As such, divers doing these dives are held towards a higher standard. It will take practice to become a technical diver. No amount of research and reading can supplement that in water time. Divers will notice that the minimum standards are often exceeded during training courses and individual technical instructors often do this. Technical training teaches a diver redundancy so that problems can be successfully solved 1500ft inside a flooded cave and an exit to the surface can be executed. While that sounds complex and scary it’s a necessary aspect of diving in that environment. Technical training is not only challenging but it’s fun and at the end of it the diver has a golden ticket to see parts of the world that are totally closed off to other people.
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.
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.
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).
