Quick answer
Scan fragments that unlock information, movement, storage, or safer returns before chasing cosmetic or comfort unlocks. Record where fragments appear so patch changes are easier to verify.
Second-screen dive plan
What to do, what proves it, and when to leave
Scan nearby fragments before traveling far.
Fragment room at 00:25
Scan one objective chain, note duplicates, leave when the blocker is solved, and do not full-clear blind.
Blueprint Collectibles
Fragment room
Fragment routes are easier when every room or wreck section becomes a checkpoint.
Approach
Scan one objective chain, note duplicates, leave when the blocker is solved, and do not full-clear blind.
Objective
Fragment route anchor for scanner-driven unlocks and duplicate-scan decisions.
Return
Use this when random scanning is producing duplicates instead of progression unlocks.
Tactical brief
How to use this guide in a real dive
Scanner Fragments Guide is useful when the player needs a repeatable decision path, not just a short answer. Start with the page objective, then compare the map anchor, the first evidence frame, and the current Early Access status before committing to a longer dive. This keeps the guide practical when Subnautica 2 routes shift between patches.
On the atlas, this guide is tied to Scanner Fragment Sweep. Treat that marker as a route anchor: Fragment route anchor for scanner-driven unlocks and duplicate-scan decisions. The important player action is not simply reaching the dot, but using it to decide when to approach, what to scan or gather, and how to leave cleanly.
The first visual check is Fragment room (00:25). Use that frame as the reading order for the rest of the article: identify the landmark, confirm the objective, then watch for the mistake that would force a reset. Fragment routes are easier when every room or wreck section becomes a checkpoint.

Field manual
Scanner Fragments Guide field manual
Built from the supplied route videos and local frame captures so the article teaches what to watch for, not only what to click.
Scan fragments that unlock information, movement, storage, or safer returns before chasing cosmetic or comfort unlocks. Record where fragments appear so patch changes are easier to verify. Use this resource route manual as a second-screen checklist: identify the entry condition, confirm the objective with a visual proof point, then stop when the return rule is met. This keeps the article practical for Early Access patches without pretending every coordinate or state is final.
Primary job
Blueprints
Scan nearby fragments before traveling far.
Best entry habit
Scanner access
Prioritize mobility, storage, power, and base utility.
Stop condition
Ignoring fragments after unlocking the first tools.
Treat duplicate scans as confirmation of a biome pattern.
What to watch in the videos
Pause on Fragment room and identify the landmark, depth band, or objective state before following the next step.
Use Blueprint progress to confirm what changed; if the video only shows a close-up, rebuild the route from the previous landmark.
Treat Databox check as the exit rule: finish the objective, return, and update storage or crafting before adding side goals.
Decision table
Ignoring fragments after unlocking the first tools.
Reset to the last confirmed landmark or objective state, then repeat only the route-critical step.

Route hint

Resource route matrix
What to farm, why it matters, and when to leave
This table turns scattered material notes into a second-screen route plan: priority, blocker, proof, and storage rule in one place.
Route band
North cave and plateau-edge sweep
Blocker solved
Electronics, scanning, and early upgrade recipes
Proof rule
Confirm the cave entry and node frame before widening the run.
Storage rule
Keep a labeled Silver reserve for tool and module recipes.
Main risk
Inventory drift before reaching the cave mouth
Route band
Northeast ravine and trench wall
Blocker solved
Base, power, and survivability construction
Proof rule
Anchor the route to ravine shape, not a single lucky node.
Storage rule
Separate base-building Lead from mixed mineral storage.
Main risk
Dropping into ravines without a clear exit angle
Route band
Thermal pocket past the Welcome Center direction
Blocker solved
Repair and early utility crafting
Proof rule
Use thermal terrain as the first clue, then confirm pickup.
Storage rule
Keep only a small working stack until recipes demand more.
Main risk
Heat, visibility, and oxygen pressure stacking together
Route band
Mid-shallow mineral route band
Blocker solved
Recipe-specific electronics and modules
Proof rule
Start from the recipe screen, then collect the target count.
Storage rule
Store Gold by recipe plan, not as general shiny overflow.
Main risk
Farming without knowing which recipe needs Gold
Route band
Reported rare-material band
Blocker solved
Rare-material upgrade bottlenecks
Proof rule
Record entry landmark, pickup shape, and safe exit line.
Storage rule
Treat it as rare until the same band works twice.
Main risk
Mistaking a discovery pickup for a repeatable route
Route band
Rare shelf and node route
Blocker solved
Rare upgrade and crafting bottlenecks
Proof rule
Confirm node, hazard, return path, and recipe amount.
Storage rule
Label the source route so later recipes do not erase context.
Main risk
Rare-material sweep turning into a deep detour
Scan priority
Blueprint unlock matrix
What the unlock enables, where the route starts, and when to come back with better tools.
Blueprint pages work best when every scan has a job: base workflow, vehicle depth, scanner routing, or upgrade crafting.
Scanner Station
Targeted resource runs and blueprint cleanup from a working base
Route band
Base-linked scanner route
Proof point
Station console and filter list
Return rule
Use one filter per blocker and stop once that blocker is solved.
Common mistake
Leaving every filter active until the map becomes noise.
Tadpole Depth Modules
Safer access to deeper objectives and late resource bands
Route band
Depth module fragment chain
Proof point
Module menu showing MK1 or MK2 depth unlock
Return rule
Install and test the module on a known route before opening a new depth band.
Common mistake
Diving into the new depth limit immediately after installation.
Wakemaker
Faster swim routing and safer return timing
Route band
Mobility fragment route
Proof point
Final blueprint check after required fragments
Return rule
Return once the blueprint completes and test mobility near base.
Common mistake
Continuing fragment hunting after the mobility unlock is already complete.

Fragment value depends on the blocker
A fragment is valuable when it removes the next blocker. In early access, this page tracks categories before pretending every spawn is final.
What to do with duplicate scans
Duplicates still tell you something: the area likely belongs to that unlock family. Note the biome and keep moving.

FAQ
Fast answers before you dive
Is this guide for the current Subnautica 2 build?
This page is written for Early Access and includes a visible update date. Treat exact values as tracking notes until the current build is field-tested.
Does this page use official screenshots?
Pages combine attributed official Steam / Unknown Worlds media, local gameplay frame captures, and source-video evidence cards. New player-submitted captures should keep the route, timestamp, and build context attached.

Near starter shallows
Approx. 70-120m from pod
Confirm oxygen before leaving the first landmark. The route is much safer when you mark the return path before collecting side materials.
