Professional Association of Diving Instructors - PADI

PADI is the world’s leading scuba diver training organization. With more than 6400 PADI Dive Centers and Resorts, and more than 133,000 individual PADI Professionals who have issued more than 25 million certifications around the world, you’ll find PADI diver courses and scuba diving services nearly everywhere. The PADI System of diver education is based on progressive training that introduces skills, safety-related information and local environmental knowledge to student divers in stages. PADI courses are student-centered and provide maximum practice and realistic application. PADI Professionals make underwater exploration and scuba diving adventures possible while maintaining the highest standards for diver training, safety and customer service. PADI’sFour E's Philosophy” is that the dive lifestyle requires four elements:

• Education: Beyond simply learning to scuba dive, you expand your capabilities as a diver through continued education. PADI’s full range of diver courses introduces you to new underwater activities and can even help you make a career move to become a PADI Professional. • Experience: PADI dive shops offer a variety of experiences from local dive tours to exotic dive travel. Diving is a social activity and, by affiliating with a PADI Dive Center or Resort, you can explore dive sites nearby or visit vacation destinations around the world with others who share your interests. Logging in to ScubaEarth® also provides opportunities to interact with other divers. • Equipment: Scuba gear makes diving possible. The best place to learn about all the fun gadgets and new scuba equipment available to you is at your local PADI Dive Center or Resort. • Environmental Conservation: A healthy underwater environment is essential to good diving and divers are great advocates for protecting our water resources. Throughout PADI courses, divers learn the importance of protecting fragile aquatic ecosystems and are encouraged to become involved in local and global conservation efforts. For more than two decades, PADI has partnered with Project AWARE® – a global nonprofit organization dedicated to protecting our ocean planet – one dive at a time.

Technical Diving International - TDI
Technical Diving International - TDI

Technical Diving International was one of the first agencies of its kind. It’s focus was and still is on providing training materials and education for specialized diving situations ranging from Nitrox to Closed Circuit Rebreathers, as well as for overhead environments such as caves and wrecks.

Your Technical Training Solution

The Technical Diving International (TDI) diver training program is straight forward, proven effective and offers divers a comprehensive path from Intro to TechTM to Advanced Trimix. Formed in 1994, TDI has built a reputation for a complete curriculum that includes cavern to full cave, decompression diving, trimix, and wreck penetration training. We also offer four levels of diver certifications on closed-circuit rebreathers to a depth of 100 metres or 330 feet. Round these offerings off with programs for gas blending and preparing equipment for oxygen service and the program selection is complete. Simply put, TDI is a one-stop technical training solution that you will not out-grow. Applications to Suit All Conditions and Environments
Technical Diving International believes that local conditions demand local knowledge. While our programs are structured to deliver a solid understanding of technical diving and develop skills that are universally applicable, our instructors are encouraged to go beyond the minimum allowable to produce courses that account for, and that are tailored to, location specific environments. For example, diving in the North Atlantic may require a different approach than drift diving in the warm waters of Indonesia. Our training makes sure you are qualified as well as certified. Should you desire a career as a dive professional, TDI & Scuba Diving International (SDI) offer: Divemaster (DM), Assistant Instructor (AI), Instructor, IT Staff Instructor and Instructor Trainer (IT) at the professional level.
