Some of this is just repetition but...The zoop does nitrox. As for the aqualung i think i will sell it. The consensus seems to be i dont need a 2nd and if i do it should be same make as my primary
If you don't need the extra money and have any interest in the aqualung as primary, then try it out. See if you like it better then the zoop. If not, then sell it. Unless...
If you want a backup computer and will commit to always diving with two, and it is a bit of a hassle, then keep both. If you do decide to keep them then the aqualung will likely need to be your backup and use the zoop as your primary and follow it for your NDL just as you do now. There is nothing wrong diving two computers with different algorithms but you got to know how to do it.
