To effectively find specific resources like Magnetite or Lithium in Subnautica using the Scanner Room, follow these detailed steps:

1. Build the Scanner Room
To begin, you need to construct the Scanner Room using your Habitat Builder. The required materials typically include:
– Titanium: Gathered from scrap metal found in wrecks or the seabed.
– Copper Ore: Mined from limestone outcrops.
– Gold: Found in sandstone outcrops or common in wrecks.
– Table Coral Samples: Harvested from the coral structures in shallow biomes.

Once you have these materials, access your Habitat Builder and choose the Scanner Room to place it in a suitable location.

2. Power Supply
After building the Scanner Room, it is crucial to ensure it is powered adequately. The most common method is attaching solar panels, which generate power during the day. Remember that the Scanner Room consumes energy while actively scanning, so establishing a reliable power source is essential for uninterrupted scanning operations.

3. Activate the Scanner Room and Choose Resource
Once the Scanner Room is powered, enter the interface to activate scanning. The room will automatically scan its surroundings for any detectable resources. You can browse through the list of detected elements and select specific items such as Magnetite or Lithium. Once you select a resource, the Scanner Room will focus its scans on locating that specific item within its operational range.

4. Use Scanner Room HUD Chip for Efficiency
To further optimize your resource-finding efforts, consider crafting and installing the Scanner Room HUD Chip. This upgrade allows scanned resources to appear directly on your HUD (Heads-Up Display). With this chip, you won’t need to constantly check the Scanner Room interface, as resource locations will be indicated on your screen while you explore.

5. Range Upgrades
Enhance the functionality of your Scanner Room by crafting range upgrade modules. Each upgrade increases the scanning radius by 50 meters, which is particularly beneficial when searching for resources that may be located farther from your base.

6. Locating Magnetite and Lithium
– Magnetite: Typically found in deeper, rocky biomes. After selecting Magnetite on the Scanner Room interface, it will display the precise locations of Magnetite deposits in the vicinity.
– Lithium: Often appears in the form of sandstone chunks scattered throughout the environment. The Scanner Room is adept at recognizing these distinct resource types and will mark them accurately when scanning.

Summary
To effectively locate Magnetite or Lithium in Subnautica using the Scanner Room, first build and power the room. After activating it, select the desired resource from the scanned items list. Using the HUD chip provides added convenience by overlaying resource locations on your display. Additionally, employing range upgrades can enhance your scanning distance, making your resource collection expeditions more efficient. By following these steps, you will streamline your resource gathering process in the beautifully crafted underwater world of Subnautica.
