My Cobra has been great. 200+ dives and am only on my second battery.

Well looks like my new Cobra2 money will be sent to another company!
I had the same problem with my Vyper. I was diving between 3 and 8 meters for 999 minutes a couple of times :14: (not really, just for my DC) so I decided to call Suunto. They told me that it can't be repaired, probably they'll offer me a discount for another Suunto 
My next DC won't be a Suunto.

I've got a question that sort of expounds on this topic. I've got a Suunto Vytek. As this is an air-integrated computer, what would everyone/anyone recommend as a redundancy gauge if it suddenly fails? Just the basic chromed brass pressure gauge? I'm trying to keep my rig as streamlined as possible. thanks!
I have a D9 with 138 dives, 120 hours under water. No problems.
I dive a Vytec, but always have a SPG, even if I am using wireless AI function. There have been too many instances of syncing problems, or loss of signal during a dive, for me to trust the reliability of the AI function. Don't get me wrong, I love the Vytec, have never had any depth sensor issues, and like the conveneince of the wireless AI function. But, I still periodically check my SPG during a dive, to compare with the Vytec reading. I would not start a dive with just the Vytec and transmitter, and no SPG.Shark_whisperer:
i thought i could dispense with the the spg and dived with the vytec and transmitter for about 50 technical dives.
then the transmitter, then the computer ,let me down at crucial times of my dives.i think my best dive wa 280m for 180mins!
i think there's a lot to be said forgood old mechanics and run times.
especially as we get no feedbackk from Suunto

wow, just came across this thread. I just ordered a cobra2 two days ago, so I'm crossing my fingers that some of these issues have been improved or they are isolated to a few bad runs of product. Anyone have these problems on the cobra2? I gues we'll see 
The simple truth is that *any* instrument can fail. A gauge or computer reading shallower than the actual depth is a particularly insidious failure mode, of course, but that's why you dive with redundancy.
If you have a buddy, just make a point to validate your depth readings against each other. If you're solo, have your secondary source of information. If ever two instruments do not fall within appropriate tolerances, follow the more conservative for the moment and check both instruments afterward.
There are few things in diving that are immune to failure, after all. (Large blocks of lead are absolutely dependable, at least for non-saturation-diving time scales. :biggrin
