How to Get Tadpole Depth Module MK1 in Subnautica 2
Tadpole Depth Module MK1 is the bridge between early exploration and deeper alien routes. Use it before chasing deep resources and late-game tool upgrades.
STATUS: Last updated: 2026-05-23 · Game version: Early Access — exact route and pickup point need current-build verification.
QA Quick Answer
Tadpole Depth Module MK1 is the practical bridge between early exploration and deeper alien routes. Get it before chasing Celestine, Conduit Crystal, Feedback Resonator, or Depth Module MK2. Bring the Repair Tool and a route marker before the long route.
📍 Location
| Reported route | Far eastern / marker-based route toward a deep wreck-card or module pickup |
|---|---|
| Required prep | Tadpole access, Repair Tool, supplies, route marker |
| Recommended stage | After early tool basics, before deep resources |
| Verification note | Exact route must be checked in current build |

🧰 Requirements
| Requirement | Why it matters |
|---|---|
| Tadpole access | The module upgrades vehicle depth. |
| Repair Tool | Deep vehicle travel is risky without repairs. |
| Route marker | The reported route is far from base. |
| Resource planning | Related resources may be needed for crafting. |
| Current build check | Pickup route may change after patches. |
🧭 Step-by-Step Route
- Confirm Tadpole access and repair readiness before leaving base.
- Prepare supplies before a long route away from shallow safety.
- Follow the current-build signal or landmark path toward the depth-module pickup.
- Collect or scan the module recipe item when found.
- Return and craft the module before attempting deeper resource routes.
- Recheck the route after major Early Access updates.
🧪 Uses
MK1 opens safer access to deeper resources, alien ruins, and tool upgrade routes.
| Use case | Recommendation |
|---|---|
| Deep resources | Use MK1 before Celestine and Conduit Crystal routes. |
| Alien structures | Pair with Repair Tool and route markers. |
| MK2 planning | Complete confirmed MK1 path before chasing unconfirmed MK2 info. |
⚠️ Common Mistakes
- Jumping from shallow routes straight into deep alien structures.
- Going without Repair Tool.
- Treating MK2 guidance as valid before MK1 is complete.
- Publishing exact route claims without current-build verification.
