5.1. The Suunto RGBM
Suunto’s Reduced Gradient Bubble Model (RGBM), utilized in the Suunto Cobra,
predicts both dissolved and free gas in the blood and tissues of divers. It is a significant
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 profiles.
