We have a new Cobalt 2 firmware version we are making available here, at least until Atomic has it up on their site. We would appreciate any feedback from Cobalt users- please respond to this thread or to me directly- we would really like to know what you think. This version was created in...

A couple of Cobalt users have contributed suggestions fo field repairs to the quick-disconnect fitting when you discover the O-ring is leaking. Paul’s suggestion below for using the Cobalt A/C charger as an aid to installing the small O-ring is brilliant. The O-rings are difficult to install...
