Cobra vs Atmos AI

I bought a Suunto Cobra last year and I don't have much to complain about (only 70 dives on it), except it is too conservative on repeditive dives. I dove along side my brother last year in Cozumel and his Aries Atmos AI was fine while my Cobra went into decompression mode on day four while averaging four dives a day. I want to do the Flower Gardens in Feb or March and I understand that they won't let you dive if your computer goes haywire like mine did.

I'm really considering an upgrade to the Atmos of I can't fix this problem.

Has anyone had this problem or have any sugestions?

It will not go into deco mode if you ascend when you get close to hitting the NDL time.

I don't think it was in dec mode, I may have exagerated on that as the computer didn't lock down.

If I follow the safety stops that it indicates and my tables, it should be fine, right?

The cobra is a more sensitive computer, and I ran into the same problem in Nassau last April. My cobra and another divers suunto both had issues, while other divers were down for longer. I don't mind the extra bit of conservitive-ness, but you can adjust the sensitivity of the cobra. Check the manual, available from Suunto online or your copy that came with the computer.
