Your Tadpole just got slammed into a rock shelf for the third time. Hull integrity is dropping. You have no way to fix it. That's the moment every new Subnautica 2 player realizes they needed the Repair Tool about 20 minutes ago.
Here's the thing: the Repair Tool is one of those items that feels optional right up until it absolutely isn't. Vehicles take damage from collisions and hostile creatures, your base can take hits, and without a way to patch things up, you're either rebuilding from scratch or swimming home empty-handed. The good news is that all three fragments needed to unlock the blueprint are within a reasonable swim of the Lifepod, so you can grab this early without venturing into anything too dangerous.
Where the three fragments are hiding
Unlocking the Repair Tool blueprint requires scanning exactly 3 fragments. Unknown Worlds has scattered more than 3 across the starting area, so there's a decent chance you've already stumbled across one without registering it.
The three most accessible locations are:
- Chap's base - inside a small cave roughly 220 meters southeast of the Lifepod, about 40 meters deep. The entrance sits at the base of a stone pillar. NOA will actually send you here early on to collect Chap's blackbox, so this fragment is practically handed to you as part of the story.
- Shipwreck directly south of the Lifepod - approximately 300 meters out, across the deep gap. Swim to the south side of the wreck to find a small entrance, then drop through the hole in the floor to reach the lower level. The fragment is sitting on a sofa.
- Shipwreck to the northeast - around 380 meters from the Lifepod at roughly 60 degrees northeast. Swim underneath the hull and through the floor opening. The fragment is on the ground next to a locked door. This wreck also has a Processor, Tadpole, and Bioreactor to scan while you're there.
What it costs to craft
Once all 3 fragments are scanned, the blueprint unlocks and you can build the Repair Tool at a fully functional Fabricator. The material cost is straightforward:
None of these are hard to source from the starting biome, though Sulfur requires a bit more searching than the others. Titanium Ingots need to be processed through a Processor rather than picked up directly, so factor that in if you're still setting up your base.

Why players keep forgetting to build this
The Repair Tool gets overlooked because Subnautica 2 does a decent job of keeping your hand tools functional without it. Batteries handle tool degradation, so nothing in your inventory actually breaks. The gap in that logic is your vehicles and base structures, which do take real damage and can't be swapped out with a fresh battery.
Players exploring the survival games genre for the first time tend to learn this the hard way after their first Tadpole collision. Veterans of the original Subnautica will recognize the pattern immediately.
The Repair Tool also doubles as a door-breaker in specific locations, which isn't telegraphed particularly well by the game. That northeast shipwreck locked door is the clearest example, but keep an eye out for similar interactions as you explore further from the Lifepod.
For a full breakdown of every tool available in the game and the materials needed to craft each one, the Subnautica 2 complete tool crafting guide covers the whole kit. And if you're still working through early blueprints, the Subnautica 2 guides collection has everything from Scanner locations to base-building basics to keep your playthrough moving forward.
