Vyper air or VT3 ?

[sarcher1]

I have a Vyper Air and I am find it to be an excellent dive computer. I have had Suunto Eon's and Cobra 2's prior (they both are still in use by family members) and found them to be extremely reliable and easy to use. If my memory serves, you can program the sunnto's to be on a certain channel, if you will, so you do not have the conflict of reading someone else's tank.

From experience, the differences in algorithms are so minute that in recreational diving this should never be an issue. I can't speak to Suunto, but I know my Oceanic DATAmask read more liberal than my dad's MARES Nemo Air.

I might suggest that you need a bit more experience, then. Suunto in particular can be very different from Oceanic when you get near the no deco limit.

While not a concern typically with new divers, it is with anyone with a low SAC rate or diving bigger tanks.

Two weeks ago, one of our divers doing a wall dive in the Bahama's, on the very first dive of the day managed to get a 14 minute deco obligation using a Suunto, while her buddy (using an oceanic) had none. Our deco person got sat down for a dive (no deco allowed rule), and the other one got to dive.

It obviously does not matter much if you are doing 35 min dives at 60 ft, but stack up say 6 dives (liveaboard), with each near the no deco limit and it can be huge.

Note: The issue our diver had was the profile she dove, not so much because the Suunto is so much more conservative... different shapes seem to be calculated differently.

Thanks all for your recommendations !

Ihave to second this. My vyper gives me a deco after dices of 40 feet or so. Not long mind you but it still says to do them.

If one of you will be using the Suunto then you should get another one, unless you want to pay big bucks for the oceanic model with dual algorithms.

Otherwise the person with the Oceanic will get frustrated having to sit out dives and end dives quickly due to having a buddy with a Suunto.

Of course you could dump the Suunto and get two Oceanics.
