Sonar in Barotrauma is used to navigate the underwater abyss, locate objectives, and identify threats. Some installations and handheld items have the added benefit of mineral finding.
Sonar Installations
Handheld Sonar
Sonar Modes
Passive Sonar
Passive sonar works by simply listening to sounds being emitted around it's surroundings. As it doesn't emit any sound waves, it allows the player to pass by hostile Creatures without triggering them. Though this makes navigating the submarine harder as you will need to be close proximity for the sonar device to detect what is around it.
Active Sonar
Active sonar works by emitting sound waves in all directions to detect what is around it. Though this may pose a danger to the player and crew and hostile creatures will now be able to detect your submarine if in hearing range. Since it emits sound waves in all directions, it provides an easier navigating experience.
Directional Sonar
Utilizing the same mechanics as Active sonar, Directional sonar allows the player to direct the direction in which the sonar emits sounds. This allows one to view one's surroundings without triggering nearby Creatures.
Mineral Scanner
The Mineral Scanner allows one to detect nearby Minerals, utilizing the Active sonar (required). Any detected Minerals will display a small hexonal dot. Hovering the mouse over these will show the name of the Mineral
Collectable plants, such as Sea Yeast Shroom, will not be detected by the Mineral Scanner.
Visible Objects
Humans
Both crewmates and pirates will show up while they are swimming in the water outside the submarine.
Creatures
All Creatures are visible to sonar.
Wrecks
Dormant, destroyed submarines are usually identified by a large oval teetering over the edge of an underwater cliff. These wrecks are sometimes occupied by an aggressive creature that takes over the sub's guns and uses them when threatened. Approach these from the bottom and sides, not from the top.
Pirates
(To do)
Ice Spires
Long, green lines jutting out from cavern walls are Ice Spires. These can be destroyed with turrets or a Plasma Cutter, breaking the ice and making the area immediately passable.
Currents
Strong currents capable of pushing, pulling, and shaking the submarine are visible as wavy blue lines.
Ballast Flora
The parasitic Ballast Flora will appear as tiny blue specks.
Sonar Flora
Orange speckles identify a zone of Sonar Flora, disrupting the sonar signal in that area.
Piezo Crystals
A bright white chunk identifies Piezo Crystals, capable of short-circuiting submarine electronics when approached, and will explode violently when destroyed.
