Better Diving Mod Wiki & Guide
wiki.9minecraft.net/better-diving-mod/
Better Diving is a comprehensive overhaul of Minecraft's underwater mechanics, introducing Subnautica-inspired movement, oxygen management, specialized diving gear, and modular vehicles like the Seamoth.
Overview
Better Diving (Work Like Fish in Water) transforms the vanilla Minecraft ocean experience into a fluid, exploration-focused environment. Heavily inspired by the game Subnautica, the mod replaces the clunky vanilla swimming with 360-degree movement, overhauls the oxygen system to allow for longer dives, and adds a progression system of diving suits, oxygen tanks, and vehicles.

Whether you are playing on 1.12.2 or 1.16.5, the mod provides the tools necessary to turn the ocean from a hazard into a viable home and resource hub.
