📋 About This Mod
Swim Charge Fins (and other custom fins that implement the same behaviour) will now also charge your inventory tools if you have no held tool or if it is fully charged already.
This is the base subnautica version, the Below Zero is here https://www.nexusmods.com/subnauticabelowzero/mods/189
This version is for Subnautica 2. 0 "Living Large" update, the Subnautica Legacy version for QMod is here https://www.nexusmods.com/subnautica/mods/576
FAQ:
Q: Will this charge loose batteries in my inventory?
A: Not by default but there is a config option in the mod menu options to enable just such a functionality.
Q: I've got swim charge fins on but nothing in my inventory is charging?
A: This is usually the result of using the Seaglide which as you're constantly discharging it via use and constantly recharging it via swim charge. The mod will never move on to charge your inventory items as the held item always takes priority.
Feel free to let me know if you have any questions not answered above.
