I use the Vytec with AI as my primary, but also use the Cobra as a redundant computer.
Yesterday I had multiple dives and noticed a fairly significant disparity between the two computers. Yes, I had remembered to program the correct mix in BOTH computers for each dive, h/e, immediatly after the third dive my Cobra was showing 80% 02 exposure, and the Vytec only 20%. On my last dive, in 133 fsw, I left when my Vytec showed 2 minutes of no-deco bottom time. It never went into deco. H/E, upon hearing my Cobra, I looked and saw that I had 10 minutes with a 10ft ceiling. I wasn't too concerned about locking out the computer since it was my last dive, but made the stop just to be safe.
Hmmm, why is one computer giving me a mandatory deco stop, and the other is not? Are these not the same algorithms?
