  • A Survival Multitool is needed to cut the pouch.
  • These are Subnautica 2 recipes.

The Scanner is missing, unpowered or not finishing a scan

Keep one finished battery for any separate use you are planning; the calculator allocates each entered battery to a selected Scanner. If you need a spare in addition to the Scanner, reserve it outside the stock you offer to this plan.

Buddy System changed the Repair Tool to two scans. That count does not establish the requirement for every tool. Follow the named blueprint and the matching guide instead of treating an old video’s count as universal.

Prepare before a fragment trip

Craft the battery before the Scanner. Watch the charge bar and carry a spare charged battery on longer trips. On the default keyboard binding, R opens the tool’s recharge controls.

Scan each equipment fragment fully and check blueprint progress. Since Buddy System, acid sources appear as green dots on the Scanner HUD.

Bloom Biofilm displays a black square or placeholder icon

Hotfix 2 fixes a black square while scanning the Bloom Biofilm sample in a habitat and a placeholder Bloom Biofilm icon. It also corrects habitat display-case scan data and an overly small battery scanning hitbox. These are specific scan and UI fixes; they do not change this Scanner recipe or the separate tool-fragment requirements.
