My partner and I both have Cobalts and absolutely love them but lately they have been getting a little temperamental. One seems to think its always 66 degrees Celsius and today it didn't log the dive. It showed the air for the dive but that was all. Luckily I dive with an oceanic bud and could safely continue the dive with my cobalt relegated to a very expensive air gauge. The other computer's problem is the select button almost never works. You press it and after about 20 pushes it gives up and works.... once.
Both of these computers are from the recalled batch but our dive shops supplier has said that due to a change in the distributor of Atomic here in Australia... we cant send them away yet to have them checked. We have a much anticipated dive trip due in March and wondering if anybody can offer some advice on getting them sorted out before we leave. The computers are both 10 months old.
Sorry for those problems. We have heard it's been hot down there, but 66°C seems a bit extreme.
The one that has not been displaying correct temperature and now, apparently, is not sensing pressure has a malfunctioning pressure sensor- the temperature and pressure come from the same sensor. That is a serious failure that will need to go back to Atomic. The button issue is most likely- particularly if it's been getting worse- due to poor coating on the button magnet allowing corrosion. That is a very easy fix. I linked to instructions for checking under the keypad a few messages above this one. You can check by seeing if the SELECT button works better when you place one of the other keys in that depression. If corrosion looks like the issue, Atomic can just send you a new keypad- the coatings have been improved to prevent this problem. Obviously you have older units.
However, if these have not been checked for the recall that should certainly be done- it takes minutes, and while few computers have had a problem, we want everyone to make sure.
What I would suggest is contacting Atomic directly to explain. Email works well for them, Adan has been handling many of the Cobalt service issues:
adan@atomicaquatics.com. There is also a contact form on the Atomic website
Atomic Aquatics. I'm sure that they will be very responsive and will get things fixed/ checked for you. Monday is a holiday here for many businesses, I'm not sure if they will be off or working, but I am sure you will hear from them as soon as possible. It should be no problem to get things sorted out before your trip.
