I am wondering if the Vision electronics are worth the extra money. The scruber sensor seems like the best feature as the co2 is the thing that makes me most nervous diving a CCR. The auto setpoints, and compact size seems really nice for traveling also. But, it is alot more money. I am not too worried about onboard cpu and think my VR3 will do just fine.
Some observations:
1. The features of the Vision are undoubtedly more impressive than the Classics. However, the Vision is relatively new. From what I have heard and seen, APD seems to have ironed out most of the initial issues, but it is still a fairly new unit on the market.
2. As for CO2 monitoring, I wonder whether it is worth all the extra money. CO2 can become an issue in three cases: (1) over extending the scrubber life (i.e. more than 3 hours), (2) forgetting the O-ring on top of the scrubber and (3) incorrect packing. The first two are not really issues for which I would spend a heap of money as I can easily control these. As for the third, I don't know whether the temp stick would always measure this (it works with temperature readings, not CO2 measurements), but packing the scrubber is not difficult at all. If I were to upgrade my unit to a Vision, it would have a temp stick, but I don't think that I would upgrade for the temp stick.
3. A big advantage of the Vision is that it has a HUD. It may not seem like much, but it is certainly very nice to have.
Best wishes with the choice!
