The Subnautica 2 improved fins upgrade is and essential blueprints that you're probably going to be looking for before you've even crafted your first pair of basic fins. Much like the devices that grant you more oxygen, better fins are just one of the quintessential Subnautica items that make your life underwater that much simpler.
To get the improved fins upgrade in Subnautica 2, you'll need to find three discarded pairs of the fins and scan them, thus unlocking the blueprint. Luckily, they're all very close to each other, but that location itself is a few hours into the story. I'll try and be as light on spoilers here as possible, but you should be warned this is mid-game content so proceed with caution.
How to get Improved Fins in Subnautica 2
You won't get improved fins until the mid-game, once you've obtained the Subnautica 2 heat adaptation and found the tadpole pens key code. If you haven't, turn away now to avoid spoilers, and come back when you have!
Once you've explored the tadpole pens, you should have received a new location marker for 'Alien Ruins'. Using your tadpole (it's a long journey), head over to this exciting new waypoint, which really sets the story in motion.
Once you've found the Alien Ruins habitat, improved fins can be found and scanned at these three nearby locations:
- Follow the cable out of the Alien Ruins habitat for 60m, 165 degrees south southeast, 160m below.
- Keep heading in the same direction for another 170m (236m from habitat), 190m below the surface.
- directly below the one above
To get to that last one, you'll need to exit your tadpole at around 250m below to ensure you don't damage your vehicle. That said, you will be surrounded by Needlers which also do significant damage to your tadpole, so make sure you've got a repair tool and some flares to hand and be as quick as possible. You've probably already got your Subnautica 2 Rebreather by now, but if not, you'll need that too.
In this new area, you'll also find some brand-new materials, including Conduit Crystals, which you'll need to craft your new improved fins, alongside Fiber Mesh and your old basic fins. Read our separate guides on those if you need help finding them.
