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.

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.
Academics - A technical course's academic portion is very similar to other scuba classes. Students will be required to do self-study and share their new knowledge with their instructor. Although the dive planning requirements for technical courses are more complex than what most people are used to, they are essential in executing a successful dive. The gas management portion of the planning discussion for overhead and decompression diving will take more time than most divers are used. A computer program is used to calculate the gas volumes and reserve required for each dive.
Although I have not yet mastered the art of Sidemount diving, I am proud to be a Sidemount diver.
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.
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.
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.
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.
- 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).
