Really? Do we have to stress that one?.
Experience says YES.
It might be a rebreather bunny that lives in travel cases and suitcases or that Mr. Murphy is a TSA agent, I’m not quite sure yet. I do know that one of them loves to ruin sensors, hand tight connections, o-rings, corrugated hoses and all sorts of yummy stuff.
The extended range of rebreather consumables and replacement parts makes it impossible for us to provide with a full inventory. Special requests made with anticipation can be arranged but as a general thumbs rule you will need to bring your own consumables, spares and special tools.
