Frequently Asked Questions

As we receive more questions submitted by visitors to our Website, we will be updating this page.

Who is SDI?SDI was founded in 1999 and grew out of success of TDI - largest technical certification agency in the world. SDI staff are all active divers, SDI training materials are best in the industry and really geared toward producing a 21 century diver.

Does the agency matter?In Open Water diving training, your instructor´s personal scuba diving skills and ability to teach are much more important than the agency affiliation. SDI is a member of Recreational Scuba Training Council along with SSI and PADI and shares the same minimum training standards. We represent SDI because we like the SDI teaching philosophy, procedures and the quality of teaching materials is outstanding.

This is also true for technical diving training but agency now begins to play a larger role. Training agencies like IANTD and TDI, that started and developed training materials and methodologies long before technical diving became mainstream, have proven track record of producing excellent technical divers. NACD has the highest requirements for becoming an instructor in the industry and is one of the two ´cave training only´ organizations in the USA.

How to choose an instructor?Some of the questions you might want to ask your instructor - how often does he or she dive outside of teaching courses, what kind of diving is your instructor´s primary interest and how much you can benefit from his or her experience.

What is technical diving?All non-commercial diving is categorized as recreational and within recreational diving there is sport and technical. Sport diving includes your open water certification, advanced scuba diver, and many other specialty courses. Technical diving picks up where sport diving ends - generally at nitrox (a breathing gas with oxygen levels greater than 21 percent).

What is my first step into technical diving?Nitrox is most divers first step into technical diving, but it has also become very popular among sport divers so TDI Advanced Nitrox and Decompression Procedures would be a great start. Advanced Nitrox and Decompression Procedures provide the foundation of technical diving and all other courses will build on the knowledge and skills learned during these courses.

Do I have to go deep for technical diving?No. Although technical diving is commonly thought of as deep, there are a lot of courses that stay within the sport diving limits (40 m / 130 feet) such as Advanced Nitrox, Semi Closed Circuit Rebreather (SCR) and Closed Circuit Rebreather (CCR) and Advanced Wreck to name a few.

Will technical diving allow me to go deeper?Yes. TDI has course curriculums that take you as deep as 100 m / 330 feet and do so in a manner that each course builds on the last and each course takes you a little deeper. By receiving training in this manner not only are your skills and knowledge increasing but so is your comfort level.

Am I more likely to get hurt engaging in technical diving?Technical divers constantly work on refining their skills and technical dives are more structured and better planned than typical open water dives. Even though no amount of training or specialized equipment can eliminate all dangers associated with diving in overhead environment, statistics show that technical diving related accidents happen at about the same rate as accidents among open water instructors and are about four times less frequent than open water diving accidents.

Do I need different equipment for technical diving?Yes. You can find a list of minimum recommended equipment to start your journey into technical diving here. Certain technical diving activities may require additional specialized items, of which you´ll learn during the course of your training. One example is equipment for cave diving.

Are there any technical diving opportunities in Utah?Yes. Take a look at our Utah Cave Diving page as well as the list of Utah dive sites. There are several submerged structures and wrecks in Flaming Gorge, two large airplane wrecks in Lake Mead as well as many smaller boat wrecks and buildings.
