How to unlock Bioscanner in Subnautica 2

One of the first things you’ll do on your Subnautica 2 adventure is to build a tool using resources extracted from the ocean below. These tools will stay by your side, help and support you throughout your experience.
Of course, there comes a time when these tools may begin to slip in their use and require a little maintenance. A scanner is one such tool.

Foams have the power of world destruction!
The Scanner is one of the first things you create and is essential to understanding the world around you, as it scans minerals and organisms for information. In the last part of Early Access, you can upgrade the Scanner to Bioscanner, which not only allows you to scan new things but also gives you interesting. recipes and plans that will help you move forward.
Let’s take a look at this new tool and how we can get our hands on it.
Bioscanner area
Before we see what the Bioscanner is used for, first you need to swim down and scan one under the waves so you can replicate it on the bottom.
You really should have a High-Capacity Air Tank at this point. This upcoming crash isn’t particularly confusing, but the longer you have oxygen life, the better, in case you get lost.
First, you will need to travel Southeast from the Alien Ruins hub. You want a big one Cicada crash that looks like falling off a cliff. This is a special crash directly south of the main Axum Turbine and east of the tall Methane Gas tower.
You have on the north side of the crash, you will see a door with a bright yellow item under the door. Enter the wreckage and take a right through the first door you see. Go straight into the next room and take a left.
At the end of this next room, there will be a hole in the floor that you can enter, lit by a bright light. Walk through the glowing red tunnel until you emerge into a large open space. When you’re down in the air, you may find a leaking oxygen tank on the ground.
Jump over this gap, swim to the next area, then swim down. Below this shaft, you’ll find the last crash chamber, and a Bioscanner lying on the floor. Scan this, then exit through the nearby door. You will come out below the danger.

You will now have your own enhanced scanner. You can use this to scan the various life forms in the sea world to unlock Biomods in Biolab. This will unlock many useful active and passive effects to give you an edge when exploring.
In addition, you will also need a Bioscanner to scan broken Axum turbine. This will give you information on how to fix it and proceed to the final stage of Subnautica 2’s Early Access.
