CONTINUOUS DECOMPRESSION WITH SUUNTO RGBM
The Suunto Reduced Gradient Bubble Model (RGBM) utilized in the Cobra predicts
both dissolved and free gas in blood and tissues of divers. It is a signifi cant advance
on the classic Haldane models, which do not predict free gas. The advantage of
Suunto RGBM is additional safety through its ability to adapt to a variety of
situations and dive profi les.
In order to optimize how to respond to different added risk situations an additional
category of stop, referred to as a Mandatory Safety Stop, has been introduced. Also
a countdown for the Recommended Safety Stop is included. The combination of
stop types will depend on the specifi c dive situation.
To get the most from the safety benefi ts be sure to read the summary of the Suunto
Reduced Gradient Bubble Model on page 62.
