After a call to Atomic and a follow-up email, my Cobalt was repaired and it should be back in my hands by tomorrow. I still wonder about the longterm reliability of the computer and wonder if I need a backup.
Sorry I didn't catch your earlier comment, but for some reason I missed getting the notifications for a few days.

Atomic, in my experience, has been excellent at taking care of any problems in a timely fashion. If you let them know when you need something, they will do whatever is physically possible to take care of a customer- not just over computers, I think you will find this is their reputation with all their products.

I've looked at most of the problems that have occurred with the Cobalts since introduction (bear in mind that thousands are in use now), and every one that occurred in the first 9 months or so. I don't think you need a backup any more than you would with any other dive computer- it's always a prudent idea to back up with an alternate gauge, particularly if you're going on a big trip. But, based on my 30 years in the scuba industry, and even more years as a diver, the Cobalt is no less reliable than other sophisticated computers. The percentage that have problems is small.

In other posts I've detailed where the problems to date have been- and by far the largest number have been with updating firmware or the divelog program, and in every instance except one (where there was a bad USB connection in the Cobalt) the issue was with the user's system, or operator error. If one only reads the forum posts that fact does not necessarily come through, as typically the issue is resolved offline.

The second most common issue has been with buttons that worked, but not well enough, or became very hard to activate. This has required a lot of tweaking and is typically fixed by adjusting the strength of the magnets. It sounds as if you might have one that was not quite adjusted right. This summer the switch positions were changed and we started getting more consistent sensitivity from the manufacturer, this means the adjustment is much less critical, and this issue seems to have disappeared.

There was a batch issue with a leaking seal in very early production, this was quickly tracked down and repaired. But some dealers got several of these, which looked bad to them. This was an assembly/ process issue.

HP hoses sometimes fail- on all instruments that have them- but the Cobalt's QD fitting can in a pinch be easily changed over to any standard HP hose.

While there have been a smattering of other issues, there have been no other consistent problems, just occasional component failures, O-rings, etc. Believe me, no manufacturer is free from these kind of problems, though few are as open about them as Atomic has been. Atomic does wet test every one before it leaves the factory. While nothing made by humans is perfect, we're developing a pretty strong track record with the Cobalt. There are thousands of users, and our biggest challenge by far has been making enough to meet demand.

SB forums have become a default support page for Atomic, so any issues, whether problems, questions, feature requests, user issues, failure to install Windows drivers, whatever, from thousands of users, get a very public airing. I's important to read the posts in any forums like this with some understanding of what they represent. To my knowledge, every problem brought up here has been addressed positively except one- there is still no case being shipped with new Cobalts :(.

I hope you get your Cobalt back and have a good trip, please feel free to contact me if you have any questions.
 
RonR, do you know/can you say if there's any plan to offer tri-mix capability for the Colbalt, either as a firmware upgrade or in a forthcoming model?

Yes, but I can't give you a time frame for any actual product. The algorithm is inherently capable of being used with trimix and constant PPO2, but of course the user interface needs to change to allow for inputing more mixes and % He. It's there "under the hood". I'm not sure there would be much call for a trimix console, but for the wrist mount yes.
 
Dived again with my Atomic today, i do like this machine and its very very user friendly. My biggest gripe is the dive log software. Where it gets its average depth from i get no idea! I dived an inland quarry, max depth of 12 m and i went no where near the bottom on the first dive (Max 7-8m) but average depth is logged as 13m?

2nd dive logged avg depth of 15m and max depth of 7m? Ill stick to my good old paper log and use the log book on the machine thanks. That said it should be sorted as some people want an electronic logbook. It was advertised as part of the inclusive price, we paid for it and it should work.

Jim,
What does the Cobalt say the average depth was in its internal logbook? That should be where the dive log software is getting it. If they are not agreeing then it seems like a bug in the desktop software. Is this with the latest version of the Windows software or an older one? I believe in the 1st version released the desktop software was attempting to calculate the average depth based on stored samples, since the Cobalt originally didn't display average depth. The Cobalt's internal value will be much more accurate, since it is based on many more samples.

Just to clarify, the Cobalt is updating average depth continually, every few seconds, so this value should be accurate.

The internal log book is fine, reports the avg depth that i would expect it to. I guessed it was the desktop software but i only downloaded it and updated the firmware on the machine yesterday. Something needs fixing i reckon.

Sounds as if that is the case. I'll check it out here and pass it along to Atomic. Thanks for the notice.

Hi Ron,

I attempted the 1.12 update on my Cobalt this evening and it has completely died. None of the remedies on the AA website will wake the DC.

A bit of clarification: I started the install, per the instructions. I'm trying this from an Mac running Lion. Started the process, never stopped and never got the date/time screen. Followed the instructions for a failed install. The install does not behave as described e.g., unplugging the DC during the update does nothing. Sits there with the moving barber pole. I don't thing the computer recognizes the DC being plugged in.

Also tried from a windows machine. As soon as I start the update, I get the message "Connection Closed." Again, looks like the computer doesn't recognize the DC.

Can you pm me the hard reset instructions? Thanks.

A bit of delay getting this up on the Atomic website, but apparently the Mac updater does not play well with Lion- the program starts, but does not complete the download. We're working on it but for now don't run the Mac updater under Lion. I'm sending a PM with instructions, sorry.

Thanks for the quick response, Ron.
