Greetings from Little Cayman Reef Resort,
Question for Ron or anyone who has had a similar issue. Checked my gear before leaving Fl and all seemed well. This AM prepping for first dive and air is leaking at hose/computer connection. Without computer connected, no leak so when the computer is in place apparently it creates the leak.
Is this fixable by any dive shop or does it require special Atomic tools and parts?
Thankfully, I had my trusty Galileo Sol, which worked fine, but a bummer to have the high tech Cobalt and not usable .
Thanks for any help.
This is most likely a worn O-ring, which should be fixable by any dive shop. Depending on if it's coming from the QD to hose connection or from the QD to Cobalt area (which fits what you are saying) it will be different O-rings. There is a small O-ring on a male stud inside the QD fitting that fits into the Cobalt's side of the QD. Atomic uses rings that are a bit harder than the standard durometers, but in a pinch standard ones will work. Atomic does recommend annual maintenance on these parts, I believe.

Ron--
Partly apropos of the post above, I'm thinking of getting an Oceanic Bud as a backup to my Cobalt. If I do, which of the algorithms in the Bud most closely matches the one used in the Cobalt?
I have been in contact with the poster above, and we determined that he has a LP sensor that has failed. When readings are bad, the Cobalt locks out the sensor and won't display depth.
Regardless of computer, it's a good idea to have a simple, basic backup, at least on any big trip where equipment failure would be a major disruption.
As to the algorithms, it's difficult to say- what matches fairly well in a shallow, single dive no-deco time sense- giving similar no stop times- might not fit in a multi-day diving scenario, or with deco diving, or with deeper dives. They aren't simple functions, so different types of diving profiles will fit in differing ways. In general, the shallower the dive, the more apparent differences there will be in terms of no-stop times.
Differences tend to seem more extreme in shallower, longer dives, because we treat deco/ no deco as a binary function when in reality is is a gradually increasing slope- very gradually increasing at shallow depths. So on shallower dives even a slight divergence in the algorithm conservatism can translate into many minutes more or less of no-deco time. The same computers might show much less difference- in minutes of no-deco time- at deeper depths. That probably accounts for some of the subjective differences in experience of how conservative a particular computer is.
The best way to answer your questions would be to use the simulator program on the Cobalt to map out dive profiles similar to those you would be following, and do the same on a simulator for the other computer.
