xdeep zen

I am a pretty new scuba diver. I am heading to New Zealand to dive at Poor Knights and I was having a bit of a hard time finding a clear answer on if my whole Xdeep Zen deluxe would fit in a carryon to min max the weight distribution between my checked luggage and carryon. I am assuming nobody...

Hi everyone, I'm considering getting either a Xdeep Zen or Ghost (standard), i'm doing only rec diving at the moment. I have trouble understanding if gettting the Zen make the shift to a double mount (in the futur?) possible or does it mean having a complete different backplate setup anyway ...
