New tech diver seeks computer advice

[Blackwood]

What table do you use for 30min at 150FSW?

1:1 = 30 minutes


Your point may be (reading between the lines) that it's not a "table" per se, but that wasn't really Richard's point.

But telling a neophyte "use a BT and a table" if he meant "use ratio deco" is more than a bit misleading/confusing, no?

Which algorithm does it use?

Suunto Technical RGBM algorithm

Maybe, maybe not. Many of us are intentionally obtuse in our posts (tek to tek subforum notwithstanding) so as to not hand over a potentially fatal recipe. That said, I have enough respect for Richard that I won't speak for him.

Don't know about mixed gas computers but you should probably replace the I3 first as it will become more of a barrier "tech wise" than the lack of a mixed gas computer. I'm not sure if they come in pink

Thanks for the link.

Call me sceptical but what does "Based On" mean ?

What advantages does it have over tried and tested Buhlman with Gradient factors or V-planner ?

So, once I put that Cobra in gauge mode I am forced to specifically plan on paper every dive for the entire trip, when I really would like to "just dive" the shallow rec dives with a general dive plan.

If you're comfortable enough doing tech dives with a BT/DG combo "just diving" shallow rec dives shouldn't be a big deal.

My goal in determining what dive computer to purchase is to get something that works very well for me now, and that will work for me for at least a few years to come.

IMO, the best way for you to accomplish this goal is to identify the classes that you think you want to take, research them, talk to others who took those classes and talk with instructors. Find out what equipment is required for the class and why and once you've completed the class you'll have your own foundation for determining what you need and more importantly why you need it.

Ask 5 divers what gear is the best choice and you'll likely get 7 answers. Until you truly understand your needs the responses can just end up muddying the waters. Get all the opinions you want, but I'd recommend holding off on purchasing til you've got a better grasp on the fundamentals.

It means "We don't have the license to use the actual RGBM, so we've made up our own algorithm that we think is probably close because our profiles end up similar?"

Cynic.

You know, I wonder if it makes any difference. GF are just a kludge on Buhlmann to reshape the curve. No one dives VPM any more, had to give Boyle his due (VPM-B) & add in a critical volume algo for a much nicer shaped curve.

Suunto may be using an emulation of RGBM. But if it's doing so by generating decent profiles, so what? Isn't that what being an informed & thinking diver means, to be able to look at the output & say wether I do or don't like the decay rate on that curve?
