Video watch notes
What to pause, compare, and write down
Do not watch the video like entertainment only. Use these notes as a second-screen checklist: pause on landmarks, confirm the player action, then return to the written route.
Watchlist
Watch the route start and unlock site separately; both are needed for a useful guide.
Pause on the resonator check and read what the interface actually confirms.
Notice whether the creator tests the upgrade safely or only shows the unlock moment.
Route start
The route start shows whether the unlock is accessible with the current loadout.
Action: Set a familiar return line before chasing the upgrade.
Resonator check
The check frame confirms the upgrade state and prevents vague tool claims.
Action: Read the interface, confirm materials, and note the current build.
Unlock site
The unlock site connects the tool upgrade to a real map location.
Action: Leave after the unlock and test the tool in a safer area first.
Video route timeline
Turn the video into playable checkpoints
Use this section like a second-screen route sheet. Open each checkpoint, compare the frame, do the action, then stop if your route no longer matches the video evidence. It keeps the guide useful even when Early Access shifts small placements or creature behavior.

Route decision lab
Decide if this route is worth running now
This section turns the video into a practical in-game decision. Use it before leaving base, after the first landmark, and again before entering a deeper or darker area.
Route purpose
Treat Resonator upgrades as safety tools. Unlock them through a controlled route, test what they change against a known threat or blocker, and update your loadout before returning to deeper zones.
Visual checkpoint
Resonator upgrades should be connected to the routes and threats they make safer.
Map anchor
Resonator Upgrade Test Zone in Resonator upgrade route. Use it for use this when a threat or route needs tool response instead of faster swimming.
Abort rule
Testing Resonator upgrades during a panic escape.
Field manual translation
Resonator upgrades need controlled testing because tool behavior can change with patches and route context. A good guide separates unlock route, interface confirmation, and field test so players know what the upgrade does before trusting it near threats or deep objectives.
Primary job
Unlock and test safely - Never assume a resonator upgrade is reliable until it has been tried on a low-risk route.
Best entry habit
Controlled route - Use a familiar route for the first test so the upgrade is the only variable.
Stop condition
Behavior unclear - If the effect is ambiguous, record it as patch tracking instead of fixed advice.
Patch-safe reading
Exact item positions can shift during Early Access. The useful part of this page is the route logic: what to prepare, what visual cue to confirm, what objective to finish, and when to turn back.

What this guide covers
Requirements
- Upgrade route
- Known threat
- Loadout notes
Use this if
You want a route you can follow from video evidence without needing exact official coordinates. The screenshots and steps are written to help you recognize areas, landmarks, and decisions while playing.
Early Access can move details. Treat this as a video-based walkthrough and verify landmarks in your own build.
Step-by-step walkthrough
Follow the video route without guessing
Unlock the Resonator upgrade through a route you can repeat.
Use this step as a route checkpoint, not as a promise that every object spawns in one exact coordinate. Match the landmark, compare the screenshot, then continue only if the return path is still clear.
If your game build looks different, stay with the same decision: keep oxygen safe, scan or collect the current blocker, and return before pushing into the next unknown area.

Detailed notes
Resonators need controlled tests
A safety tool is only useful if you know what changed. Test one upgrade, one route, and one hazard at a time so the result becomes guide data instead of guesswork.
How to use this in-game
Turn this note into one action before leaving base: decide the objective, keep only the materials or tools that support it, then stop the route once the scan, pickup, or landmark is confirmed. This keeps the guide useful even when Early Access patches move small details.
Route value
The best Resonator unlock is the one that makes a repeated route safer: scanning, threat avoidance, return timing, or entry into a previously risky area.

Practical field read
Sonic and Feedback Resonator Upgrades works best when you treat it as a completion route with a narrow job. Start with the loadout check: Upgrade route. Then follow the first action without adding side goals: Unlock the Resonator upgrade through a route you can repeat.. The page should help you recognize the scan, pickup, or checklist state that proves progress before you risk a longer dive. If the route starts producing unrelated discoveries, bank the note and return to the original objective instead of turning one guide into a full map sweep.
Loadout check: Upgrade route
Route check: Known threat
First action: Unlock the Resonator upgrade through a route you can repeat.

How to turn this into the next dive
After the first proof point, decide whether the route is solved, blocked, or worth repeating. Check the upgrade state before assuming behavior changed.. If it is solved, return and convert the result into crafting, storage, a map note, or the next related guide. If it is blocked, change only one variable: bring the missing tool, clear inventory, enter from a cleaner landmark, or wait for better oxygen and vehicle support. Test against one known hazard, not several variables at once.. Avoid the two habits that make this route feel unreliable: Testing Resonator upgrades during a panic escape.; Assuming the upgrade works the same after every patch..

Video route notes
Sonic and Feedback Resonator Upgrades should be followed as a completion route, not as a memory test. Start by watching the first route movement and naming the entry condition before copying the path in-game. Unlock the Resonator upgrade through a route you can repeat. Then pause again when the video reaches the first visible proof point, because that is where the guide changes from general advice into an action you can repeat. Check the upgrade state before assuming behavior changed. If the route starts to feel different in your build, keep the same player goal: finish the unlock cleanly and know whether a return trip is needed.
Entry check: Upgrade route

Screenshot checkpoints
Use screenshots as checkpoints instead of decoration. The first image should answer where the route begins, the second should show what confirms progress, and the third should explain what to do after the scan, pickup, puzzle state, or threat read is visible. Test against one known hazard, not several variables at once. This is especially important in Early Access because exact positions can drift while landmarks, depth bands, room states, and player decisions stay useful. A good screenshot lets you say, "I am at the right kind of place," before you risk oxygen, storage space, or vehicle safety.
Entry frame: match the landmark before moving deeper
Proof frame: confirm scan or pickup proof
Exit frame: know the return direction before adding side goals
Loadout frame: check Known threat

Stop rule and next dive
The most useful part of this page is the stop rule. Testing Resonator upgrades during a panic escape. Assuming the upgrade works the same after every patch. When the objective is confirmed, return and convert it into progress: craft the upgrade, sort the material, save the route note, or mark the blocker as solved. If the route fails, do not repeat the same swim blindly. Change one variable at a time: enter from a clearer landmark, reduce inventory clutter, bring the missing tool, or wait until oxygen and vehicle support match the route. That turns a failed completion route into better field knowledge instead of another untracked cleanup sweep.

FAQ
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.
