Stroke Test

[O-ring]

My big reason for wanting the Vytec is to maximize dive times at multiple levels within NDL's while on air or nitrox.

Doesn't the Vyper use the same "Haldane /w dumbed down RGBM" as the Vytec then? The Vyper is only about $300 online.

I chose the Vytec for it's user-replacable battery, hoseless integration, true "button" controls and wrist mount, very needed in zero vis conditions.

A-ha...the truth comes out. The main difference between the two is the air integration...yeah, you will have to get the Vytec for that. The Vyper isn't air integrated and the Cobra has a hose...

Will you show me the handshake if I just bring a pair of scissors?

Ok, but be forewarned, the handshake hurts..

Stroke me, stroke me! Stroke! Stroke! ..... hit a 77%. Guess i should have been dead years ago.

Yeah, I've dived the Cobra... And it certainly seems like a nice unit, if you like computers. I've also dived a relatively plain-Jane Oceanic that was wrist mounted, and really liked the way it was accessible to be all the time even in the worst conditions. I believe that the combination of the two... Basically, a wrist-mounted, air-integrated Cobra, would be my favorite. I know it's not DIR, but I think that it'll help ensure safety, while getting my guages on my wrist where I can see them.

You're right in that all of the Suunto products use a "dumbed down" RGBM model, but the Vytec and the Cobra have an adjustable "safety margin" that can be backed off to be less stingy with it's deco times. Out of the box, both of these units have the longest deco times for the shortest NDL's. In other words, the highest margin of safety. You can back off of that to more resemble some of the other computers, if you'd like. Personally, I believe that a computer at all is going to be a significant improvement over the single-depth PADI tables that I've been using.

I'm afraid to ask. Show me anyway.

I have a Vyper myself...

Re: Vytec and Cobra,

The cobra has three personal and three altitude settings, P0 and A0 being the most "liberal". My old USD hocky puck was far more liberal than the Cobra on its lowest settings (P0, A0). Not that I mind, It's just an added safety margin we have. Use nitrox if you want to extend the BTs and shorten the SIs.
Or maybe you have found something I've missed in setting up the Sunnto's.... if so, please tell.

ps. We use the misquito for backups, same/same

There is a secret less conservative setting I have been using for a few months that just may work for you. I just go into the setup menu and change the mode to something called "gauge".

 

[scubatexastony]

I'd expect that from UP, but O-Ring! Allrightyden.

His Vyper lives in guage mode too.

Yeah, I guess that was a little "puggish"....I will see if I can get my medication adjusted to prevent future outbreaks.

I didn't get to play with the Cobra too long... Only a couple of dives. When I got really interested in it, I looked up the information online, and then downloaded the demo and the owner's manual. My grand take on the whole thing was that the adjustments came in the full "safe" mode, and that they could be reduced, providing less margin of safety, but a more realistic NDL. The tests I've read on the Suunto Cobra and Vytec support the notion that they're "padded" a bit more than many other computers from the factory.

In my reads with the Mosquito and the other Suunto computers, I did not get the impression that they had any sort of similar adjustment... That's not to say that they don't... I honestly don't really know. But I had the impression that they did not have that adjustment. Perhaps that's wrong. You would know better than me, if you own the unit.

Sorry if I misled you in any way.

The only adjustments that I know of are the ones you mentioned, which I understood to "adjust" the margin of safety. Is the LEAST "margin of safety setting" still too conservative? Does the computer still need to be more liberal?

Really? And here I thought you were gonna give me heck for wanting a computer.

Oh, wait... Lemme guess... It lives in guage mode only.

All joking aside, what's your experience? How's that Vyper work? Do you use it at all? Would you, given the scenario I painted above?

I'd hate to blow mucho bucks on something just to get a very expensive bottom timer.
