I purchased a used Cobra on e-bay in December. It looked like new, and all the out-of-water functions worked well. I tested it in a pool and it seemed to work fine.
My first dive in Bonaire last week, the depth stayed at 0 and it did not register any bottom time, I assume because at 0 depth the computer didn't start the dive.
The dive shop removed the battery to reset the computer. There were a couple of drops of water on the battery, but it wasn't flooded. Back to the dive, and it registered 150' as soon as it hit water, and proceeded to climb to over 450' by the time my buddy's gauge showed 60'. The pressure display worked fine, so I finished the dive sticking close to my buddy. Out of the water it still read 400'+ depth and the alarms were still going, as well as the bottom timer.
I left the battery out overnight. Everything was dry when I took it out. When reinstalled, the depth still showed 400'+ and the bottom timer started again, as well as the alarms. I took it to a Suunto dealer, but he said the unit is sealed and nothing can be done. I ended up renting a gauge console for the rest of the trip. A week later it still showed 400'+, but at some point the alarms quit.
Of course, the e-bay seller won't respond to me, and since I bought it four months ago, there's no recourse through e-bay or PayPal. After it worked in the pool, I gave him positive feedback. Can anything be done with this, or it expensive junk?
