How to craft improved fins in Subnautica 2

A Subnautica 2 guide explains how to unlock Improved Fins by scanning three pickups near the Alien Ruins.

The blueprint is unlocked after finding all three Fin locations, including spots near the Lifepod and Tadpole Pens.

Crafting the fins at the fabricator requires materials that are easy to gather early, such as gold, sulfur, strong acid, and conduit crystals in blue pillar areas.

Improved Fins significantly increase swim speed, making early exploration, harvesting, and survival safer and more efficient.
