SUUNTOZoop Novo Wrist Scuba Diving Computer (Black)

I just came from a week of diving in the Philippines. My Zoop Novo consistently required either less bottom time or more decompression than other computers used by other divers.I believe two factors were working against me: 1) It did not seem to take Nitrox (up to 32% O2) into account. 2) It “recovered” much more slowly from previous dive days. In other words, as I accumulated more bottom time during the course of the week, it required more and more decompression stops or much less bottom time.I wonder if the algorithm needs updating?Bottom line: I got into more decompression problems on nitrox with this computer than my buddies on the same dive with air.How could that be?I would greatly appreciate your comments/suggestions.Thanks.

Great quality.
