The latest version of the Archimede computer, aesthetically redesigned and complete with new and sophisticated software that during the dive can manage two different Nitrox mixes, which can be selected at any time of the actual dive.
The already excellent features of Archimede have been considerably improved both for scuba divers and for free divers who have the new GAUGE function as an indispensable instrument that can monitor all their dives in detail.
-Bühlmann ZH-L8 algorithm, redesigned by Randy Bohrer to make it suitable for a more sophisticated RGBM program.
The result is an algorithm that is very similar to the ZH-L16, but less penalizing regarding water temperature and repeated overshooting of the ascent speed.
