Subnautica 2 Guide: How to Find and Craft the Repair Tool
Smashing your submarine into a rock shouldn't be a death sentence, but you need the right gear to fix your terrible piloting.
The ocean is full of hostile fish and jagged cliffs that will tear your vehicles to shreds. Before you blindly drive your new Tadpole into a deep cavern, you need to secure the Repair Tool. This gadget patches up damaged vehicles, fixes broken base modules, and even slices open locked doors inside sunken wrecks. The game forces you to work for it, though. You have to hunt down three separate fragments and venture into some dangerous territory to get the raw materials. I mapped out the easiest route to get this tool in your hands.
Tracking Down the Blueprint Fragments
You need to scan three broken versions of the tool before your database learns the recipe. There are several scattered around the map, but three of them sit relatively close to your starting position.
Chap's Base in the Southeast
Start at your Lifepod and swim roughly 220 meters southeast. Once you hit that distance, look down for a tall stone pillar. Around the base of that pillar is a ring-shaped hole that drops into a cave. Swim down and look back to the northwest to spot the hatch leading into Chap's abandoned base. Head inside and you will find the first Repair Tool fragment sitting right on a desk.
The Southern Shipwreck
For your second piece, start at the Lifepod and swim exactly 270 meters due south. Dive deep until you spot a massive metal shipwreck resting near some tall rocky cliffs. Look for a small door on the south side of the hull. Swim inside, take a left, and look for a cracked elevator shaft. Drop through the broken floor to reach the lower level. The fragment is sitting on a sofa in the corner.
The Northeast Hangar Wreck
The final piece sits in another giant wreck about 350 to 380 meters northeast of your Lifepod. Dive under this massive base and look for a half-open door that leads into a large storage hangar. The third Repair Tool fragment is resting on the floor next to a locked door by the window. While you are in this hangar, you can also scan a Processor, a Bioreactor, and a Tadpole fragment.
Surviving the Heat for Sulfur
Getting the blueprint is only half the battle. You can't craft the Repair Tool with basic copper and quartz.
The recipe requires Sulfur. This material only spawns far to the east in the high temperature zones. If you try to swim there normally, the water will literally boil you alive. Before you attempt to gather Sulfur, you absolutely must alter your DNA.

Crafting the Repair Tool
Once you have your Sulfur and your other refined materials, you need a proper setup. The damaged fabricator in your Lifepod cannot handle this blueprint. You must use a fully functional Base Fabricator to put it together.
What the Tool Actually Does
I know from painful experience how easy it is to scrape your Tadpole against a cliff face or take a blind hit from an aggressive fish. Pulling out the Repair Tool and holding the trigger over the damaged section restores your vehicle health in seconds. It runs on battery power, but it drains energy very slowly early on.
More importantly, it bypasses specific locks. Remember that sealed door you walked past while grabbing the third fragment in the northeast hangar? If you take your brand new Repair Tool back to that exact spot, you can break open the control panel to access the room behind it. You will find the Rebreather blueprint sitting right inside.
