Tactical brief
How to use this guide in a real dive
Tadpole Submersible 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 Tadpole Submersible Staging. Treat that marker as a route anchor: Mobility anchor for using the Tadpole as route support rather than a random travel toy. 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 route (00:53). 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. The Tadpole route starts with a repeatable heading before fragment scanning begins.

Field manual
Tadpole Submersible 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.
Use the Tadpole as a mobile return plan, not just a faster swim. Park it where terrain gives a clean exit, then run short scouting spokes from that anchor. 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
Tadpole
Choose parking spots with turn space and landmark visibility.
Best entry habit
Vehicle access
Scout in short spokes from the Tadpole instead of abandoning it deep.
Stop condition
Treating the Tadpole as invulnerability.
Keep storage organized when co-op teammates use it as a shared cache.
What to watch in the videos
Pause on Fragment route and identify the landmark, depth band, or objective state before following the next step.
Use Chassis scan to confirm what changed; if the video only shows a close-up, rebuild the route from the previous landmark.
Treat Wreck checkpoint as the exit rule: finish the objective, return, and update storage or crafting before adding side goals.
Decision table
Treating the Tadpole as invulnerability.
Reset to the last confirmed landmark or objective state, then repeat only the route-critical step.
Parking in beautiful but hard-to-exit terrain.
Use the video frame as evidence, but record entry, proof, and exit as separate notes.

Return, craft, sort storage, or retest the route before turning this page into a longer objective chain.

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.

Guide notes
The Tadpole makes routes readable
The best vehicle habit is anchoring exploration. Park, scout, return, craft, then push again. This keeps deep routes from turning into one long panic line.
Co-op vehicle discipline
In multiplayer, assign one player to vehicle position and storage calls. That single habit prevents duplicated trips and lost materials.
Risk controls
Common mistakes
These are the actions most likely to waste oxygen, lose the route, or turn a clean scan into a failed attempt.

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.
