Which type of dive tables are endorsed by NAUI?

The Reduced Gradient Bubble Model (RGBM) based tables are endorsed by NAUI because they incorporate advanced physiological models that better predict the formation of bubbles during ascent and minimize the risk of decompression sickness. RGBM takes into account various factors, such as the individual diver's ascent rate, multiple dive profiles, and surface intervals, making it a more nuanced approach to dive planning compared to traditional models. The RGBM provides a more flexible and safer framework for divers, especially when undertaking repetitive dives or dives with varying depths.

This endorsement reflects NAUI's commitment to safety and diver health, as it relies on contemporary research and understanding of dive dynamics. By using RGBM tables, divers can enhance their awareness and preparation, leading to safer diving experiences. The other types of dive tables mentioned may not utilize these advanced models and thus do not provide the same level of safety and risk management as the RGBM-based tables.
