Rebreathers offer an extension of diving abilities by forgoing large cylinders in favor of recycling the gas exhaled by the diver, scrubbing the CO2 exhaled, and injecting prescriptive amounts of gas from smaller cylinders. This can drastically increase the dive time compared to carrying double cylinders of the same generate size/weight, especially for deeper dives. Rebreathers can be back or sidemounted, and the profile they create is dependent on the configuration.
Divers using decompression oxygen mix all types can extend their time looking at wrecks or reefs on the oceanfloor. The sport diver may be limited to two short dives at 100ft. A decompression diver can cruise the seas for 60 minutes or longer, getting more bang for his buck.
It is becoming more popular to do technical diving and we were immediately drawn to it at Girls that ScubaHQ! We had many questions and nerves, so we went to Theresia Gollner, who is working at Blue Marlin Gili T in Lombok. We were given an introduction to twin sets by her and then she let us in on the amazing world of technical diving. Here are the lessons she gave us:
2nd stage regulator; exposure suit with side pockets, BCD-sidemount, SMB cutting tool, diving spool. Jet fins. Mask and spare mask. Technical diving equipments. 1 long hose (2.10m-7ft), hogarthian, or cave harness.

Sidemount diving requires only an Open Water Diver to begin. Although it's important to have excellent buoyancy and trim, you should also be able handle your equipment independently. Sidemount diving offers a whole new level of skill and equipment setup.
Although the gear selection is important, entry level tech divers will learn how to streamline their equipment and prevent drag. This maximizes propulsion efficiency and awareness.
New gear means new techniques. Scuba diving sidemount is easy if you have the right skills.
Technical divers dive at depths less than the recreational limit of 40 meters/130 feet. Technical divers can access underwater caves and other locations that aren't accessible by recreational diving.

Initially I had no interest in technical diving. I distinctly remember chuckling to myself at the Tec divers I saw, wondering why anyone would want to carry more equipment underwater. I love the sense of freedom and proximity to nature that can envelop you in “the silent world.” However, Tom had a reputation as an inspirational teacher, and as I was working in a dive shop with Tec courses it seemed rude not to at least try.
These are the options for you if you're looking for alternative diving lessons and classes, or if you want to find out what next steps should be taken.
Our CDS Basics Orientation course is the best option if you don't plan to use sidemount while you cave diver training.
While we are able to teach the SDI course if you ask, the default is the TDI. Although you can do this program as an individual course, we recommend that students combine it with our Apprentice Cave Diver course.
