Unless I win a serious jackpot or find that uncle who was last seen in Hamburg boarding a boat for South America many yrs ago, I am not going to dive CC in the next few years. Also, 130m rating is also way more than enough for my diving needs. (BTW, it is interesting that the differences in depth ratings are discussed in detail in FAQ on Shearwater pages, but they are not mentioned in the direct comparison of Perdix and Petrel.) So I do not need to consider other Shearwater models but PERDIX.
That leaves me w 2 options. I am considering pros and cons of AI model. It is nice to have gas metrics on the screen, however, it introduces one more element which can break, and - more important - an HP one. Also the electronics can break (though this situation is backed up by a good ol' SPG.) Also, monitoring my gas supply using SPG is already something quite automatic for me.
Let me know if I am overlooking some good reason why to buy AI? I do not want to start any feature nit-picking flamewar, I am just curious if there are some uses to this than what I can see.
