Quick answer
Current Subnautica2.gg and Subnautica2Hub data list Repair Tool as a scan-unlocked tool crafted at the Fabrication Station / Fabricator with Titanium Ingot, Wiring Kit, Basic Battery, and Sulfur. PC Gamer currently reports 2 Titanium Ingots while the database pages list 1, so check your PDA before the final craft. Build it before the Tadpole, Karakorum, or deeper power routes start turning small damage into lost time.
Field notes for repair prep
Craft it before the first scary trip
The Repair Tool feels optional until a long route goes wrong. Make it while you are calm, not when the Tadpole is smoking near a bad landmark.
Battery charge matters as much as the tool
A dead Repair Tool is just another item in the hotbar. Keep one charged Basic Battery near the kit before vehicle or base-power runs.
Sulfur is small but easy to spend
Reserve one piece for repairs. It is annoying to finish the scans and ingot work, then lose the craft to a material you thought was common.
Repair Tool unlock and craft plan
Scan first, farm second
Subnautica2.gg currently says Repair Tool unlocks after 3 scans. If the recipe is missing, do not waste a storage run on the full material list yet.
Treat the recipe as a small chain
The public blueprint pages list Titanium Ingot, Wiring Kit, Basic Battery, and Sulfur. PC Gamer currently disagrees on the Titanium Ingot count, so bring a spare if you are crafting away from base.
Build it before vehicle confidence
A Tadpole makes distance feel safe, but damage still matters. Keep the Repair Tool ready before repeated wreck, predator, or deep-resource loops.
Keep one repair kit near the base job
The tool repairs bases and systems as well as vehicles. If you are expanding rooms or power infrastructure, store a charged battery and spare sulfur near the Fabricator.
Pair it with your charger habit
A Repair Tool with a dead Basic Battery is just locker clutter. Once Battery Terminal is built, keep one charged battery beside the tool and rotate the weak one through the terminal before a long route.
Check the Fabricator after every patch
Early Access data moves. If the recipe on your save differs from the public pages, trust the PDA and update the locker labels around the real recipe.
