Incorporating consistency with real physical laws for gas kinetics • The Suunto RGBM predicts both dissolved and free gas in the blood and tissues of divers. It is a significant advancement on the classic Haldane models, which do not predict free gas. The Suunto RGBM provides additional safety through its ability to adapt to a variety of situations and dive profiles.
are available for divers who dive constantly and are ready to accept greater personal risk. CAUTION: Always use the same personal and altitude adjustment settings for the actual dive and for the planning. Increasing the personal adjustment setting from the planned setting as well as increasing the altitude adjustment setting can lead to longer decompression times deeper and thus to larger required gas volume.
Both fractions are scaled so that the diver’s maximum tolerated exposure for each is 100%. Suunto Vyper Novo does not display CNS% or OTU% but instead displays the larger of the two in the OLF% field. OLF% value is the Oxygen limit fraction or Oxygen Toxicity Exposure.
