Subnautica 2: How To Get & Use Repair Tool

Jun 23, 2026

The Repair Tool is a handheld battery-powered device used to fix damaged systems and objects in Subnautica 2. You use this tool to fix your Tadpole vehicle damage, repair base structures and broken systems, and open access to certain damaged wreck doors. The game requires you to scan all 3 Fragments to unlock its blueprint. After that, some materials are required to craft it at the Fabricator. The location of each Fragment is not that far, making it easier to find them. This tool doesn’t have durability but only loses battery charge. Let’s explore how to get & use the Repair Tool in Subnautica 2.

How to Get the Repair Tool

You don’t get the repair tool automatically in Subnautica 2. But you must unlock its blueprint first by scanning fragments. Before heading out to find these fragments, you need a Scanner tool. You can’t just simply pick them up but scan them. The objective here is to scan 3 fragments to unlock the blueprints. There are more than 3 fragments in the world, so missing one is fine. You can find them located near the Lifepod starting area (wrecks, caves, outposts). Looking to get a Subnautica 2 game key, LootBar has the best offer right now.

Repair Tool Fragment Location 1

The first repair tool fragment location 1 is the large metal base or wreck 270 meters south of the Lifepod. You must head straight south (S or S-SE compass direction). After covering enough distance, you will pass coral fields, small rock ridges, and shallow wreck debris. After that, look for a large metal structure. You will know you’re close when you see the following.

A huge wreck or base embedded in rock
Cliffside entrance or broken hull panels
Metal corridors partially exposed

Keep moving the main corridor or the left path and look for a broken equipment room. The fragment is available on the floor or placed on the table.

Repair Tool Fragment Location 2

The second location of the Repair Tool Fragment is the Chap’s Blackbox Cave or the Colonist’s Southeast Outpost. This spot is around 220-250 meters southeast of Lifepod. You will see a glowing cave entrance near a tall rock pillar.

Swim southeast from your Lifepod.
Continue moving till you reach a small wreck or bunker structure in a cave area.
Find the entrance near rocks or cliff edges.
Enter the structure and explore the area thoroughly.
Approach the bench and scan the second Repair Tool fragment using the Scanner.

Repair Tool Fragment Location 3

The final Repair Tool fragment is located 360-380 meters northeast of your Lifepod. You can easily find it inside a large, crashed shipwreck structure. Make sure to bring an air tank for extra oxygen, as the depth is usually 50m+. Below are the steps to find your last Repair Tool Fragment.

Start at your Lifepod and swim northeast for 360-380meters.
Find a large metal wreck sitting partly on the seabed.
Dive underneath the wreck hull to find a broken entrance under the structure.
Enter the interior cargo area and move through the wreck.
Eventually, you will reach a room with debris and a couch area.
The Repair Tool fragment is lying on the floor, so scan it with your Scanner.

Craft the Repair Tool in Subnautica 2

After scanning all 3 Repair Tool Fragments in Subnautica 2, the game automatically unlocks the blueprint. Make sure to have the following materials to craft the Repair Tool.

1x Titanium Ingot
1x Wiring Kit
1x Basic Battery
1x Sulfur

Once you have all the required materials, go to your Fabricator. Open the menu and click on Tools. Select the Repair Tool from the list and craft it.

Craft Titanium Ingot

Acquiring these materials can be challenging if you want to craft the Repair Tool in the early game. Titanium Ingot is not located in the world, but you craft it yourself. The game doesn’t let you craft the ingots at the basic Fabricator.

The objective here for you is to find and scan a broken Processor unit inside the Old Habitat or Cicada shipwreck area. This allows you to unlock the Processor blueprint.
Use your Habitat Builder and construct it in your base using Titanium, Copper Wire, and Mild Acid.
After that, interact with the Processor to get 1x Titanium Ingot.

Get Wiring Kit

The Wiring Kit becomes available after unlocking basic electronics crafting or early-game scanning. Collect the Copper in early caves near the Lifepod or shallow seabed outcrops.

Use the Copper Wire to craft 2x Copper.
Silver is located in slightly deeper cave systems near Lifepod.
Once you have Copper Wire & Silver, use them in the Fabricator to get the Electronics Tab.
This material usually produces the Wiring Kit in Subnautica 2.

Craft Basic Battery

The Basic Battery is not found in the world, but you craft it at the Fabricator after getting the ingredients. You must have 1x Copper and 1x Acidic Raion Pouch to craft the Basic Battery.

Break small copper ore outcrops in caves near your Lifepod to get Copper.
Acidic Raion Pouch is found on purple cave plants. You must use your knife to harvest the pouches from the plant body.
Interact with the Lifepod Fabricator and use these materials to craft Basic Battery.

Get Sulfur

The Sulfur in Subnautica 2 is located in the rock pillar near volcanic vents. This area is about 200-250 meters southeast of your Lifepod. This spot is near the Coral Crabs and the Welcome Centre route.

You must initiate Lifepod and go southeast about 120°.
Look for a tall isolated rock pillar on the open seabed.
Circle the pillar and pick up small sulfur crystals directly.

How To Use Repair Tool

The Repair Tool in Subnautica 2 is the early-to-mid-game tool used to repair damaged technology, vehicles, and base structures. You also use this tool to unlock multiple sealed areas inside wrecks. Repair tool lets you:

Fix damage on your Tadpole submersible.
Restore hull integrity after collisions or creature attacks.
Patch base hull breaches
Restore damaged base modules and systems
Repair early-game systems like the radio and fabricator panel.
Open blocked wreck doors to pass through sealed wreck entrances and unlock access to loot and blueprint areas.

This battery-powered handheld tool uses a high-energy repair beam. Repair is basically done by reconstructing damaged material at a structural level. You must aim at a damaged object, hold the trigger, and the object’s damage meter goes down until fully repaired. Once unlocked, the Repair Tool is crafted at a Fabricator. The Repair Tool does not break or wear out by using it constantly. However, it runs on battery power. You must swap batteries or recharge them later when empty. The best possible way to use the Repair Tool is:

Point at the damaged area
Hold the interact or fire button
You’ll see a repair beam or arc effect
Wait until the damage is fully fixed

Conclusion

Repair Tool in Subnautica is essential for long-term progression. Without it, several early-game areas are simply not accessible or functional. Find 3x Repair Tool fragments and scan them with your Scanner. Once complete, the blueprint unlocks automatically. Fragments are commonly found inside Cicada wreck modules, colonist bunkers, and near early coral dome structures. Once unlocked, craft it using Titanium Ingot, Wiring Kit, Basic Battery, and Sulfur. The only way to use the Repair Tool is to aim at the damaged objects and hold the interaction button. Buying Subnautica 2 game key from LootBar at a discounted price and instant delivery.
