Buhlman gf settings compare to Sunnto vyper2

[Zvalle]

Hi'

Plan to get a new divingcomputer for decodives. Today i use a Vyper2 and my plan is to keep it as a backup.
My new computer is to be a Sherwater Petrel and it use Buhlman with gf.
Anyone how can give me any suggestion what i should set the gf to for matching my suunto on a good way. I want a setting that's when the sherwater told me to go up one level the suunto already told it. I understand its diffrent's algoritms and i cant get it exactly but so close it's possibly.
I'm only dive with one decogas and don't use helium.

It's not what you're asking for, but I'd suggest keeping your Vyper2 as a back-up in gauge mode with tables. Use V-Planner/Multi-Deco to create your tables - they will exactly match your Petrel (whether Buhlman or VPM is used).

Today i dive with my uvatec bt and my suunto in gauge mode with plans an tables. It works well on wrecks but i do a lots of reefdives there it doesn't works so well for me. Sometime i decided to go shallower than planed and wan't more time instead. That's the reason i wan't dive with computer.

Plan your dive, dive your plan. Computers shouldn't short-cut that, or make it irrelevant, especially for tech/deco.

You can easily plan multi-level dives using V-Planner/Multi-Deco... you just can't wing it 'on-the-fly' and go wherever you want, whenever you want. To do so means you haven't planned your gas, CNS% etc... you become reactive; relying on your electronics, rather than pro-actively using them.

Those computer software generated multi-level plans should correspond accurately still to your Petrel, if you have a precision approach to your diving. They'd provide the extended bottom-times through shallower depth levels that you're looking for.

I use a Suunto Helo2 and a Petral on my dives. I have yet to find a way to "sync" the two algorithms. Truthfully, I don't like my Helo2 because my body doesn't like the continual decompression. Therefore I use my helo2 as a gauge (a very expensive gauge DC). I also use VPM on my Petral which is nice since I can then plan the dive on my ipad, iPhone or Mac, cut tables (have a backup) and have both deco schedules match.
I love suunto, but only for recreational diving. Once you get into deco, I don't believe it works any better than VPM, and in my experience with my body, it works worse.
Hope this helps.

RGBM and GF is vastly different in the way they handle the shale of the the same profile. Dont bother to try and match them.

Define and plan the dive and then dive that plan. Fly the Suunto as BT and dive slates. I would replace the Suunto and get Uwatec BT. If you have the cash then keep the Suunto but still get BT.

RGBM start stops deeper than default GF and also longer. If you get the SW you can try making the GF a lot deeper. BUT.... First understand the models 100% before diving them!!!!!

Just to add to akdubb's post. The RGBM Modal that Suunto uses is different from the "true" RGBM. Suunto's model is a "get shallow quick and hang" model where RGBM has stops at every 10ft, like GF. The original RGBM still gets you shallow quick, but differently than Suunto's model. I believe Suunto calls it "Continual Decompression" or something like that.
