This instrument, whether or not a devoted gadget or software program utility, 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 may require a cease at 6 meters for five minutes, adopted by one other at 3 meters for 8 minutes, earlier than surfacing. These calculations take into account elements corresponding to dive depth, backside time, respiratory fuel combination, and even earlier dives.
Correct ascent planning is important for diver security, making this computational assist 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 provide a restricted variety of pre-calculated eventualities. Trendy instruments present customized calculations, enhancing security and adaptability in dive planning. This improvement represents a big development in dive security, lowering the incidence of decompression illness.
