Advanced Nitrox

The TDI Advanced Nitrox course at Tiedemann's Diving Center is designed for certified divers aiming to expand their depth limits and bottom times using enriched air nitrox. This technical diving program builds upon your existing Enriched Air Nitrox certification, teaching you to utilize gas mixes with oxygen percentages from 21% up to 100% for dives reaching depths of up to 130 feet (40 meters). The primary focus is on the benefits, potential hazards, and proper procedures for using these advanced gas mixes in dives that do not require staged decompression. You will learn how higher oxygen content can significantly extend your no-decompression limits when used as a primary breathing gas, reducing nitrogen absorption. Alternatively, using high-percentage oxygen mixes for decompression can shorten your ascent time or enhance safety margins during safety stops.

This comprehensive course includes three classroom sessions to cover theory, a dedicated pool session for mastering equipment configuration and rigging, and four practical certification dives. Tiedemann's Diving Center provides the TDI Deluxe Advanced Nitrox Student Kit and a Student Workbook as part of the course fee. While gas fills, entrance fees, and any potential charter boat fees are not included, the curriculum is structured to ensure you gain hands-on experience with the equipment and techniques necessary for advanced nitrox diving. The center is certified by TDI, a leading agency in technical diver training, ensuring a high standard of instruction.

Upon successful completion, you will receive the highly respected TDI Advanced Nitrox certification card. This certification is a prerequisite for obtaining cylinders filled with Nitrox mixes exceeding 40% oxygen. The course also emphasizes the importance of understanding equipment requirements, with specific guidance provided during the first lecture to help you select appropriate gear. Many students find this course is an excellent precursor to the TDI Decompression Procedures course, further advancing their capabilities in technical diving. Tiedemann's Diving Center offers instruction in multiple languages, including English, German, French, and Dutch, catering to a diverse range of international divers.

While specific dive site details are not provided, the practical application of these skills typically occurs in environments suitable for technical diving training. The climate data for the region shows a wide temperature range throughout the year, with sea temperatures averaging around 12.7°C, suggesting that thermal protection suitable for cooler waters may be necessary depending on the season of your course. The course structure, with its blend of theory, pool work, and open water dives, is designed to build confidence and proficiency in managing advanced gas mixes safely and effectively.
