DANGER The Odyssey dive computer has been designed to monitor your dive profile and to calculate decompression stop(s) requirements based on its internal model and the parameters you provide. These calculations are, at best, an estimate of actual physiological desaturation requirements and do not guarantee a safe ascent profile. Decompression sickness (DCS) is intrinsically linked to the gas load dissolved in the diver's body as a result of diving and to be off-gassed by the body during the ascent and after surfacing.
