Scanner Room (Subnautica)

The Scanner Room is a Seabase module. It is constructed with the Habitat Builder, being designed to map the terrain of Biomes via controllable Camera Drones, to scan the environment and to detect resources in its vicinity. These drones can be controlled manually.

Hatches, Reinforcements, and Windows can be placed on the Scanner Room.

Four Upgrade Module slots can be found to the right of the camera drone panel, along with a mini-fabricator.

The player must find three fragments to unlock the Scanner Room's blueprint.

Uses
In order to use the Scanner Room, the player must go to the camera station, which activates the drones. After activating, the camera drones will be controllable, and can be used to swim around the environment and map the terrain. These drones have a maximum range of about 500 meters by default before losing connection. Additional drones can be built but only two can charge at the Scanner Room. They can, however, be stolen by Stalkers who will pick them up and chew on them.

The Scanner Room will also scan for nearby resources, identifying them as red blips on the central hologram. It has a base scanning range of 300 meters and max of 500 meters. Before scanning for any peculiar item a camera drone must have a line of sight on said item, the scanner room will then add it to the list of searchable items. The scanner can only mark items in terrain that has been mapped via drones. When building a new scanner room it is advised to pilot a drone long enough until one believes they have mapped as much of the scanning range area as possible. The list of searchable items is currently alphabetical with no means of scrolling said list. Certain items such as sandstone can be on the list with no means of selecting them as other items can occupy to many of the scanner rooms list slots. Several means of working around the list are available due to the design and coding for the scanner room. The first method is to collect all the small quantity items freeing up a slot that could possibly lead to your specific item being added to the list. The second is to save and restart your game as the list of searchable items refreshes each time the game is opened. When using the second method it is advised to not collect any of the particular item that are close to your scanner room that you are going to be searching for as the further your drone needs to go to add an item to your list the more likely it will detect other items and fill up your list again. The scanner can only search for one resource type at a time and has a base time of 14 seconds, but the searching speed and range can be increased to take 2 seconds at max with the Scanner Room Range Upgrade and Scanner Room Speed Upgrade; you can have more of the same upgrade in the scanner room to extend the range and speed even more. Furthermore, a HUD upgrade allows the player to see where the scanner has identified the resources in a similar fashion to signal devices.
