What Is the Bioscanner?
Scan Advanced Alien Technology and Protean Biology

The Bioscanner is an essential upgrade for your standard handheld Scanner. While the basic Scanner works fine for early-game flora and fauna, you will eventually encounter advanced Axum Technology and Protean Biology (Alien items) that your starting tool cannot properly analyze.
Unlock Late-Game Blueprints
Equipping the Bioscanner allows you to scan advanced creatures and alien objects, unlocking important blueprints and Biomods needed for mid- to late-game progression.
Bioscanner Blueprint Location
Find the Fragment Inside the Cicada Wreck

To unlock the blueprint, you only need to scan a single Bioscanner fragment. A guaranteed Bioscanner fragment can be found inside the Cicada Wreck (EVA Prep). If you already have the "Blackbox – Iso" mission active, simply follow the waypoint marker to reach the wreck.
All Black Box LocationsBring a Repair Tool
You will need a Repair Tool to access the Bioscanner fragment area, so make sure to craft one before heading to Cicada Wreck.
- Travel to the wreckage site (1,700+m, 120° East)
- Find the entrance marked with "73"
- Repair the damaged door with the Repair Tool
- Follow the open doors
- Dive into the circular floor maintenance hatch
- Follow the pipe toward the red-lit opening
- Scan the Bioscanner fragment on the deck
- Repair the nearby door to create an exit shortcut

Travel around 1,700m away from your starting Lifepod toward 120° East to reach the Cicada Wreck. This is the same location tied to Iso's Blackbox mission.
All Black Box Locations
Swim around the wreck until you find the entrance marked with the number "73" near the upper-right side of the opening.

Once inside, immediately turn right and use your Repair Tool on the damaged door to open the sealed door.

Proceed through the opened doors. Inside the second room, head left to scan the Improved Fins blueprint. Iso's Blackbox can also be found further ahead on the desk.

In the room where the Blackbox is located, look to its right to spot a circular hatch in the floor and dive inside.

Swim along the pipe until you reach an opening illuminated by a noticeable red light.

Dive down through the red-lit shaft to find the Bioscanner fragment resting on the deck. Scan it to unlock the blueprint.

Repair the nearby broken door to unlock a convenient shortcut leading directly outside the wreck.
How to Craft the Bioscanner
Craft at the Modification Station

Since the Bioscanner is treated as a direct Scanner upgrade, you must use a Modification Station to craft it. Unequip your regular Scanner and combine it with several mid-game materials found near the Alien Ruins biome.
Required Materials for the Bioscanner
| Materials | Quantity | How to Get |
Scanner | 1 | Crafted at the Fabricator |
Enameled Glass | 2 | Crafted at the Fabricator |
Conduit Crystal | 3 | Found near the Alien Ruins biome |
How to Use the Bioscanner
Scan Alien Organisms for Permanent Buffs
Once equipped, your main goal with the Bioscanner is to scan rare alien flora and fauna to fulfill Biomod research requirements at the Welcome Center's Bio Lab. Biomods act as powerful active and passive mutations that significantly improve your exploration capabilities.
Unlock Powerful Biomods and Buffs
Using the Bioscanner on certain deep-sea organisms unlocks advanced abilities like emitting a sonar pulse to detect nearby resources through Sonic Echo, or generating electric discharges to defend yourself from predators.
Creatures Must Be Re-Scanned
Even if you already scanned a creature using the standard Scanner, you will still need to scan it again with the Bioscanner to complete its Biomod research requirements.
