Well, I go away for a few days and look what happens… Seriously, not sure about weighing in here, but will add a few comments from my perspective.


First, I completely sympathize with free_electron's frustration, he's had two failures that should not have happened, plus the uncertainty generated by the recall. I wouldn't call the recall a failure, as it was a response to a very tiny number of computers in the field that appeared to have been improperly assembled. Atomic, out of a proper abundance of caution, decided to check all computers that had been manufactured prior to their instituting the new assembly process that made this problem impossible. I will add a couple of reassurances. The little ball/ glue seal in the battery compartment is actually a very good design- not high tech, but simple and rock solid reliable. And we have taken many of these batteries and subjected them to saltwater immersion, dead shorts, destructive abuse, etc. and have only come up with a weak fizzle- that's what the overpressure ball would release, if needed. These are not batteries likely to burn.


But I want to also make several points.
Diving is a tiny, specialized market. Trying to compare diving equipment manufacture to the standards set by manufacturers of electronics (or other) products where many millions are sold is just not going to be productive. The hard economic facts are that the resources available to those manufacturers- including pre production testing of large numbers of products to uncover rare failure modes- are not remotely possible for diving products. This is a market where sales are measured in the thousands.


Once a manufacturer has made essentially the same design (a small, round puck, for instance) for years, they will have largely worked out the bugs in manufacture, and reliability will probably be good. When new designs are developed, despite best efforts and good design, there are sometimes issues that turn up in the field that just did not appear in the sample numbers used for testing. That did happen with the Cobalt, and from nearly 30 years involvement in this business I can tell you it's happened to some extent with every new product I've been either part of or aware of. This isn't because manufacturers want to use consumers as testers, it's because of the small size of the diving market precludes the kind of testing that mass-consumer level products get. And building production is never the same as building prototypes. The large majority of early Cobalt adopters have not had any problems at all (and therefore don't post them here), but some have, sometimes repeatedly. Forums like this one, and Atomic's willingness to be open about any failures, tend to amplify those issues and make it seem as if they are much more common than they are.


As developers, we want to see two things when problems do happen:
First,we want to see Atomic being responsive to any consumer problems, and doing everything possible to make things right for the user ASAP. That isn't always 100% possible, but Atomic has, in my view, done an outstanding job of customer support. Compare Atomic's openness and responsiveness to other manufacturers- I'm pretty confident you would find they are in the top tier. I do agree that if they are out of new stock at the moment (and I know they are waiting on boards now, sales have exceeded anticipations), they should have contacted free_electron and sent a demo/ replacement before now.


BUT… the other thing we want to see, and something that is not visible to users, is that any problems occurring in production or assembly are aggressively identified and fixed. Even rare failures have to be treated as unacceptable. Atomic has done a tremendous job here- quality of their products is something they take very seriously. Problems have been researched, identified, and fixed. The Cobalts being produced now are not the same as our first production a couple of years ago. Atomic has aggressively acted to change their assembly process and designs to prevent even minor or rare failures. When I look back at logs of problems from early production, I see overwhelmingly issues that could no longer occur with these changed processes.


Nothing made by humans is perfect. The LP sensor failure free_electron experienced is in a component used by many dive computer manufacturers. They fail very rarely, but it does happen to all of us. Some percentage of Cobalts will leak or fail- though I don't believe it will be any more than other computers, and now quite probably less. Windows compatibility will still give us trouble. We will keep working on ways to make upgrading firmware easier and less dependent on the desktop OS. We will keep working to make this product better and more reliable- and being very open when we fall short is a big part of this effort.

Thank you Ron for the support! From our end here at Atomic, we work tirelessly with our designers to perfect the assembly process of this computer. We will continue to work hard to fix and resolve any issues in the development and performance of the Cobalt. Thanks All!

Allright. I just got confirmation from Atomic ( and a tracking number ) that a new one was shipped overnight.
So, Big thanks to Darcy, Adan and Ron.

To pick up on what Ron wrote: Both my Cobalts were early production runs. Like I wrote in an earlier post : I suspect my machines were subject to 'teething problems'. There is indeed a big difference between making 1 and 1000.

Let's hope we can put this issue to rest once and for all and I can change the topic title to 'best dive computer ever'. Like I said : I really like the machine ,the design, its capabilities and its functionality. If this one holds up i'll be a happy diver.
 
67 dives and not a single hiccup. Gonna do another two this afternoon. This one has outlived the previous ones by at least double.
 
I have used one for two years and it's fantastic. At any time that I have had any issues with either Atomic or Scubapro and have sent queries to them, I have had immediate responses and have been satisfied.

In over 20 years of diving I have owned many computers and almost all have failed in some way. Sometimes in the middle of a dive. Anyone who takes electronic equipment underwater without some sort of backup is asking for trouble, I my opinion. I have a watch and analog SPG and depth gauge. I always compare my SPG to my air integrated computer at the beginning and end of a dive to track accuracy. Redundancy is a good thing if your computer fails in the middle of a dive which happened on multiple occasions with a Suunto. I have never had to abort a dive because of it.

My personal Atomic failure was with the charger while in the Cayman Islands. I emailed Atomic from Little Cayman and they diagnosed the issue based on my description. I had enough charge for the remainder of my trip and Atomic shipped me a new one while I was still on vacation and it arrived at my house the day after I did. I can't ask for better service than that.
 
Cobalts are strange. Sold a new pair to a guy and his wife. Wife's worked fine. He had horrible luck with his. After just a few dives it displayed him as being several hundred feet underwater when he was around 50 sending it into immediate deco mode. Think he did the firmware update and that sorted it out. After diving a few more dozen dives it started to leak from weird places and cannot be repaired. Pretty sure Cobalt replaced it and he either sold the replacement for something else or uses it as a backup.

I can see how trying a new brand and having problems like that can put a bad taste in one's mouth. I've seen it happen with GoPro and all their little firmware updates. Worse yet is installing firmware on a working camera just to have it brick as a result.

Wildly inaccurate depth display like that is not a result of any firmware issue or electronics glitch, it was a leak, almost certainly at the pressure sensor O-ring.

It's quite possible that it dried out enough or the water shifted inside so that a firmware update (which involves a reset and causes the sensor calibration constants to be reset as well) would have given the appearance of a temporary fix- at least until it leaked again. Which from what you say it did. I guarantee the firmware update did not in fact sort it out. If he had contacted us or Atomic we would have advised him to stop using it and send it in for replacement immediately. Since it didn't fail right away, and passed the wet test at Atomic, the leak was probably very slow and small, but the depth readings you describe would be a huge red flag for leaking or sensor failure- that kind of thing does not happen because of firmware issues.

This is not an example of strange behavior, it's an example of electronics failing when water- particularly salt water- gets into them. Once that happens the circuit boards are not repairable, there is too much potential for corrosion down the road.

I'm glad he got it replaced, but people trying to dive a computer (of any make) after witnessing that sort of failure with it gives me the willies.

I use tables and two bottom timers. No problema. :D
