Subnautica 2 GuideA major efficiency unlock for advanced resource routes.
Quick answer
Build the Sonic Resonator when advanced node extraction becomes your bottleneck. It materially improves route efficiency once deeper materials start blocking progression.

Route cards
Build on bottleneck
Craft it when advanced extraction becomes your current blocker.
- Do not rush it before the prerequisite chain is stable.
- Use it once hand-collection becomes inefficient.
- Treat it as a throughput upgrade, not a luxury.
Validate the gain
Revisit one known rich route after crafting it.
- Compare yield on the same lane.
- Scale it to deeper routes only after the test run.
- Keep the route short enough to reset safely.
Use in deeper biomes
The Resonator belongs on routes where hand-collection is losing time.
- Push it into higher-risk resource lanes.
- Do not skip repair and power prep.
- Retest after major patches if efficiency changes.

Where to Find It
- Progress prerequisite tool/vehicle chain first.
- Build when your route starts depending on advanced node extraction.
- Use it in deeper biomes where hand-collection becomes inefficient.
How to Use It
- Minimum viable loop: craft Resonator, revisit one known rich route, validate yield gain, then scale to deeper lanes.
- Do not rush Resonator if prerequisites still leave you depth-unsafe; stabilize vehicle + repair stack first.
- Use Resonator to unlock throughput on existing routes before expanding into new high-risk biomes.
FAQ
Is Sonic Resonator optional?
Technically optional, but strongly recommended for efficient progression.
When should I craft it?
As soon as your next bottleneck is advanced material extraction.
What improves most after unlocking?
Material throughput and route efficiency.
