APECS 3.0 almost here?

I know that I don't want the deco algorithm being run in the same system controlling and reporting PO2 without it being absolutely fault tolerant. I don't see any systems within a "middle class" price range that have this capability.....yet. So, for now, I love the APECS 2.x for it's simplicity and ruggedness. Deco is handled by a completely separate computer (Liquivision X1). For me, it's the perfect marriage.

APECS 3.0? Not interested.

I have to echo Richard’s sentiments. I’m eminently satisfied w/ my APECS 2.x electronics. They have a simple job to do and they’ve done it, rock solid, for over 2 years now. I truly value the absolute separation of deco from ppO2 control, both for reliability and upgrade reasons.

I'm not gonna shoot the horse before it comes to the race. But, I'm in with the non computor crowd.

Even though I do love the Shearwater.

I think we're going to have to add another unresolvable argument to the already long list in the Rebreather world - to have integrated deco or not

It also feels like the old Harley vs Japanese bike debate - let it run....

Going this route makes even more sense for me because it doesn't tie the decompression to just one rebreather during a dive.

Resilliancy, ruggedness, and redundancy through modularity... I don't like being locked into an integrated vertical solution.

This is fairly amazing, and quite influencing to me trying to determine the best option on the way forward. My well used, and battered

Hmm maybe a simple fix + an X1 (or a Shearwater) is in the cards after all

It's not that I wouldn't like to have integrated deco, but I really don't see it as being all that big a deal. When software gets more complex it also gets more buggy, which is why I'm pretty happy having a very basic loop controller. Keeping the deco on a different unit is a nice modular system. When I plan a bigger dive, I do it like this:

Work out the details on the laptop
Cut the tables and laminate them (wrist mounted slate)
Cut bailout tables and laminate them (also on wrist)
Fill 02 and Dil
Fill bailout using thirds
Do the dive as it was planned and as it appears on my wrist.

While I use the computer to validate my deco schedule, it is really only there for backup.

Again, it would be nice to have integrated deco, but IMHO, you should not do big dives if you can't maintain a setpoint, so as long as your actual setpoint matches that on your computer, everything should jive and you can validate the deco schedule on your wrist.

It's tempting just to jump in, do a gnarly dive and depend on your computer to get you out of it, but doing so ignores some of the basic safety precautions of technical diving like proper gas management, which is a risk that I really don't feel comfortable taking.
