Quick answer
Prioritize Tadpole Depth Modules when the next objective sits below your current safe band. Find the module fragments, confirm MK1 or MK2 in the upgrade menu, install it, then test on a known route before diving deeper.

Module route
Depth module runs should begin only after depth is the real route blocker.
Approach
Confirm the module, install it, test on a known route, then open the new depth band.
Objective
Tadpole Depth Module MK1 and MK2 planning anchor for deeper objective bands.
Return
Use this when depth is the blocker, not when a flashy optional module would merely be nice.
Tactical brief
How to use this guide in a real dive
Tadpole Depth Module 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 Depth Module Chain. Treat that marker as a route anchor: Tadpole Depth Module MK1 and MK2 planning anchor for deeper objective bands. 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 Module route (00:20). 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. Depth module runs should begin only after depth is the real route blocker.

Field manual
Tadpole depth module test manual
Built from the supplied route videos and local frame captures so the article teaches what to watch for, not only what to click.
Depth modules should be evaluated as route gates. The useful evidence is the module route, the MK1 or MK2 confirmation, and a safe test before deeper exploration. This keeps the guide from encouraging players to dive straight into a new threat band after installing an upgrade.
Primary job
Open the next depth band
Depth is critical when the next objective is physically below the current safe limit.
Best entry habit
Module proof first
Use the upgrade menu to prove the module state before changing route plans.
Stop condition
No test route
Do not use a new depth limit on an unknown route until the module is tested safely.
What to watch in the videos
Watch the route to the module source before the menu appears.
Pause on MK1 or MK2 confirmation and connect it to the depth band it opens.
Look for whether the creator tests the module on a known route before diving deeper.
Decision table
Depth is not the current blocker.
Delay the module and solve storage, scanning, or base workflow first.
The module is installed but untested.
Run a short known route before opening a new deep objective.
A deeper route has poor visibility or threat pressure.
Treat depth access as permission to scout, not permission to loot everything.
Screenshot reading order

Module route
The route frame tells players whether they are ready to chase the module at all.
Player action: Bring only the tools needed for the module route and leave side pickups alone.

MK1 check
The MK1 frame proves the upgrade state and should change only the next planned route.
Player action: Install, test near a known area, then update the route plan.

MK2 plan
The MK2 frame belongs to deeper progression and needs stronger support.
Player action: Check storage, power, threat response, and exit plan before using the new limit.

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

Loadout and prerequisites
Route timeline
Follow the run in order
Built for second-screen use: complete each checkpoint, then move to the next landmark before detouring for extras.
Check whether depth is the real blocker before chasing optional modules.
Follow the fragment route and scan only confirmed module targets.
Open the upgrade menu and confirm whether MK1 or MK2 is unlocked.
Install the module and return to a familiar route for a first test.
Push into the new depth band only after the vehicle and exit plan feel stable.
Guide notes
Depth modules are route gates
A depth module is valuable because it changes where the Tadpole can safely operate. The guide should connect each module to the objective band it opens.
Safe test rule
After installing MK1 or MK2, test the new limit on a known route before using it for a dangerous objective. This separates upgrade confidence from exploration risk.
When to delay MK2
Delay the next depth module if the deeper route still lacks power, storage, or threat response. Depth access without route support can make the next trip worse, not better.
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.
