A Complete Guide to the Repair Tool in Subnautica 2: How to Find and Use It

Introduction

The Repair Tool might seem like a humble gadget, but it's absolutely essential for survival in Subnautica 2. Unlike many survival games where you constantly fix your own tools, here your equipment only needs fresh batteries. However, your vehicles—like the nimble Tadpole—and your underwater bases will take damage from collisions, hostile creatures, and the environment. You don't want to rebuild everything from scratch. That's where the Repair Tool shines.

To craft one, you'll first need to unlock its blueprint by scanning three fragments scattered near your Lifepod. Once you have the blueprint, you can assemble it at any Fabricator with common resources. This guide covers exactly where to find the fragments, how to craft the tool, and all the ways it can save your expedition.

Finding Repair Tool Fragments

There are more than three fragment locations, so you may have already picked up one or two while exploring. Each fragment is a small, glowing device that you scan with your handheld scanner. Here are the three most accessible spots near the Lifepod:

Fragment 1: Chap's Base (Southeast)

Head roughly 220 meters southeast of your Lifepod, descending to about 40 meters deep. You'll find a small cave entrance at the base of a stone pillar. Inside is Chap's base—NOA will send you here early on to retrieve Chap's blackbox. On a desk inside the base, you'll spot the Repair Tool fragment. Scan it to add one piece to your collection.

Fragment 2: Southern Shipwreck

Directly south of the Lifepod, across a deep gap, lies a shipwreck about 300 meters away. Look for a small entrance on the south side. Swim through, then drop through a hole in the floor to reach the lower level. On a sofa in this area, you'll find the second fragment.

Fragment 3: Northeastern Shipwreck

Travel about 60 degrees northeast of the Lifepod for 380 meters. You'll see a wreck you can enter by swimming underneath and through a hole in the floor. Once inside, the fragment is on the floor next to a locked door. This wreck is also a goldmine for other blueprints—you can scan a Processor, a Tadpole, and a Bioreactor in the hangar.

After scanning your third fragment, the Repair Tool blueprint will unlock automatically.

Crafting the Repair Tool

Return to a fully functional Fabricator (the one in your Lifepod works) and use the following materials:

• 1x Titanium Ingot (crafted from 10 Titanium)
• 1x Wiring Kit (crafted from 2 Copper Wire, 1 Silver Ore)
• 1x Basic Battery (crafted from 1 Acid Mushroom, 1 Copper Ore)
• 1x Sulfur (found in outcrops or from certain creatures)

Once crafted, the Repair Tool goes into your inventory and equips like any other tool. It uses battery power, so keep spare Basic Batteries or craft a Charger for your base.

Using the Repair Tool

Repairing Vehicles

The primary use is fixing your Tadpole submarine. It's easy to scrape against rocks or collide with terrain, and hostile fish like Bonesharks can chew through hull integrity. Simply equip the Repair Tool, approach the damaged vehicle, and hold the use button until the health bar is full. I always carry it as a backup—trust me, you'll need it often.

Opening Locked Doors

The Repair Tool can also unlock certain doors that block valuable loot. For example, inside the northeastern shipwreck (where you found the third fragment), you can use the tool to break open a locked door. Behind it lies the Rebreather blueprint, which allows you to stay underwater longer. Always check for such doors; they often hide rare schematics.
