Doubles water gained from every source — drink a Water Slug for 80 instead of 40, cook a Halfmoon for 30 hydration instead of 15. This is the single best passive for long Tadpole expeditions and the 251–450m turbine-repair tier where you're 600m from a refill.
Unlock: Bioscan Coral Crab (Shallows / Coral Gardens, depth 0–50m). 6-second scan duration — one of the longest in the game; bring Oxygen Control and approach from behind.
Effect
x2 water from all sources (40→80).

Notes
Stacks effectively with Water Secretion (passive +5 water every 3.5min) for a near-zero-thirst loadout. Replace once Cherimoya Rotsacs and an established Bioreactor make hydration trivial.
