This instrument, whether or not a devoted system or software program software, computes ascent profiles for scuba dives, significantly these exceeding leisure depth limits. It makes use of mathematical algorithms based mostly on fuel absorption and elimination ideas to find out protected ascent charges and required decompression stops, stopping decompression illness. For instance, a dive to 40 meters would possibly require a cease at 6 meters for five minutes, adopted by one other at 3 meters for 8 minutes, earlier than surfacing. These calculations think about components similar to dive depth, backside time, respiration fuel combination, and even earlier dives.
Correct ascent planning is essential for diver security, making this computational help indispensable for technical {and professional} diving. It permits divers to discover deeper environments whereas mitigating the dangers related to dissolved gases within the physique. Traditionally, divers relied on dive tables, which supply a restricted variety of pre-calculated situations. Trendy instruments present customized calculations, enhancing security and suppleness in dive planning. This improvement represents a major development in dive security, decreasing the incidence of decompression illness.
