Sorry if my posts are ambiguous. I'm simply stating that out of about 20 divers on the 3 tank wrek trek, the 2 divers using Zoops were limited to significantly shorter dives, doing similar profiles to the rest of us, because Zoops are much more conservative.
You asked about depth and bottom times- The Spiegel Grove sits at 130', our average depth was in the 60-80' range because there's a lot of superstructure and good stuff to see at that depth, the Duane is upright in about 120' and our average depth was about 80' spending our time at or above the main deck, and the Bibb lays on its side at 135' which makes the average depth closer to 90-100'.
Dive times were about 25 minutes on the Duane, 20 minutes on the Bibb and 45 minutes on the Spiegel Grove.
Who would care? I would care if I was using a computer that -to me- has a rather arbitrary limiting algorithm that chopped significant amounts of time off of my dives or forced me to sit on the line, doing deco stops that are not necessary when diving other computers with less conservative algorithms. Also- we're all diving AL80s so if a diver is forced to do deco stops they're going to have less bottom time on the wreck because they need the extra gas for those deco stops.
