All you need is glass, titanium, and silver ore to make the High Capacity O2 tank at your fabricator once you got the blueprint.
First, you need to find the blueprints for the High Capacity O2 tank in the wrecks and debris fields around the map. After that, just head back to your fabricator and craft it with some glass, titanium, and silver ore!
Honestly, prioritize your tank upgrades early in the game. It makes exploration so much smoother. Personal experience: saved my life more than once while diving deep!
Don鈥檛 forget to scan fragments at wrecks for better tank blueprints, or you鈥檒l be stuck with the basic one forever!
