The Bühlmann ZH-L8 algorithm has been refined by Randy Bohrer in order to make available a more complicated RGBM program. The result is an algorithm very similar to ZH-L16 which is less penalizing related to water temperature and exceeding ascent rates.
12 Tissues with saturation hemi-phases between 5 and 640 minutes
Dive data full processing. During air or Nitrox dives (including decompression dives) two different nitrox mixtures may be
Setting of mixtures
P02 can be set between 1.0 bar to 1.6 bar. FO2 settings between 21% to 50% and 21% to 99%. The Archimedes II will allow for a nitrox dive subsequent to an air dive even during de-saturation. Possibility of PROGRAM setting (depthometer/timer)
Large UFDS display system allows for ease in reading and understanding of values.
Replaceable display protecting screen
Battery replacement by user
Manual dive planning (Scrolling), Dive simulator (surface interval setting for a subsequent dive)
Unit of Measure
Unit of measure changing from metric to feet and °C to °F.
Sound and visual warning systems
Nitrogen saturation graphic indicator, CNS oxygen toxicity graphic indicator
Calendar and clock
Logbook (30 h or 60 dives) including dive profile, Dive historical memory
