Understanding Flashlight
A battery-powered light useful when exploring dark wrecks and caves.
This is an original reference for the first Subnautica. Your current depth rating, oxygen, available tools and navigation route determine when an objective is practical. Follow actual in-game PDA and Fabricator information for any values that vary by version.
How to use this information
Carry a backup battery and use visibility deliberately to reduce orientation errors.
What to avoid
Extra light does not change oxygen or pressure limits.
