Unified Team Diving
UTD Specialties: RATIO DECO

 

Using Ratio Deco requires a series of requisite parameters including, but not limited to, complete situational awareness, cohesive team diving, standardized UTD back-gasses and deco mixtures, along with a through understanding of the Ratio Deco methodology and all it’s parameters, and the discipline to stay within those limitations. The user of Ratio Deco must acknowledge the need to build real-life, in-water experience with the through study, practice and an awareness of risk vs. benefit.
This class covers in detail all the aspects of Ratio Deco, or what is better known as “Decompression on the Fly.” We will start with the history of decompression modeling, Henry’s law, Haldanean theory, US Navy, Workman, Bulhmann, VMP and RGBM, and most importantly how we apply these to personal decompression strategy. You will also understand the overall concept and curve and how to essentially do “Deco On the Fly”. The class will end with examples and exercises.

The goals of Ratio Deco training are:

To develop the student’s practical knowledge and understanding of current and past decompression theories.

To enable the student to create an organized and safe plan for decompression without primary reliance on traditional tables or computers.

To create a “thinking” decompression diver who is able to adjust for changes in a dive profile during the dive.


Prerequisites

• Minimum 18 years of age
• UTD Rec 1 or Open Water certification from a recognized agency
• Nitrox certification is not required but is strongly recommended
