Atomic Cobalt pressure reading issue.....

[shortkidd]

Has any Cobalt owner experienced this issue?

Diving on Friday night....computer was fine on first dive no issues.....on second night dive I set up my gear and predive check there are no issues. I jump in and start descending and the tank pressure reads 0, the computer starts beeping because it thinks I have no pressure at depth. I finish my dive because I dive with two other computers and I am all good there. Also, the Cobalt accurately recorded the dive just with 0 pressure. Which is fine.

While on the boat, I disconnect the computer and reconnect pressurize the system and still reading 0 pressure. I brought it home and let everything dry out and connected my first stage to a tank I have at home and when I pressurize the system there is leak where Cobalt connects to the hose and the pressure is fluctuating. Is there a seal or something that needs to be replaced that I am completely unaware of?

Looking for any help. I would appreciate it.

Regards,
Vincent

Vincent, sorry for the delay in responding. Pressure readings as you describe could be caused by connection problems between the sensor and the main PCB, a sensor failure, or (less likely) a leak at the HP end. I don't think this is related to any gas leak, that probably just means an O-ring is due for replacement. Diagnosing and fixing this involves taking the Cobalt apart, so it needs to go back to Atomic for service. Sorry I don't have an easy fix. Contact Atomic service by phone or email and I'm sure they will take care of it.
