My partner and I are in Bonaire this week, diving a ton. He has a Geo 2.0 and I have a VT4. Both are set to the DSAT algorithm with conservative factor set to off. Both of us have been diving the same profiles (average depth has varied a little bit but no more than a couple of feet and not consistently one direction or the other) with EAN32.
At the beginning of a dive day, both computers have the same TLBG bars (none) and in planning mode produce the same results for the same depths. However, after a day of diving, the Geo 2.0 ends up with much shorter desaturation time remaining, fewer TLBG bars and longer NDLs than the VT4. Last night after our fourth dive of the day, the VT4 had 4 bars, while the Geo 2.0 only 1 and the NDLs in plan mode were almost half as long on the VT4.
I was under the impression that these computers run the same algorithm, but maybe something else is going on. Has the algorithm been tweaked in newer computers or is there some other setting I'm possibly overlooking?
