11 The Scanner is a handheld tool available from the start of Subnautica 2. It scans objects, creatures, flora, and technology fragments to unlock encyclopedia entries in the PDA and discover crafting blueprints for the Fabricator. Subnautica 2's Scanner has been upgraded with radar functionality for locating resources and items of interest in the surrounding area.

33 Core Function
44  
55 The Scanner is pointed at an object and held until a progress bar fills, at which point the scan is complete. Scanning a creature or plant adds its encyclopedia entry to the PDA, providing biological data, habitat information, and assessment notes. Scanning technology fragments unlocks crafting blueprints; most complex items require scanning two or three fragments before the full blueprint is available.

88 Radar Functionality

1010 Dev Vlog #1 (April 23, 2025) showed the Scanner with an integrated radar. The radar feature helps players locate materials and scannable objects in the surrounding area, reducing the time spent searching for specific items in the larger world of Proteus. The radar pairs naturally with Subnautica 2's resource-specific node system, since players know which type of node they are looking for and can target the radar accordingly.

1212 Scanner Station
1313  
1414 Scanner Station is a base module that acts as a long-range radar. Once built and powered inside a base, it can pinpoint the location of ore deposits, wrecks, alien structures, Blight infestations, and anomalies within a fixed radius of the station, then place a marker on the player's HUD for the chosen target.

1616 The player interacts with the station, selects which resource type to track, and a hologram of every detected source of that type appears above the module. Selecting one of the holographic markers pins a signal to the HUD pointing to its exact position. This makes the station the base-bound complement to the handheld Scanner's portable radar: the handheld radar sweeps the area immediately around the player, while the station surveys the wider area around a fixed base.

1818 The Scanner Station blueprint is unlocked by scanning Scanner Station fragments, which are found inside derelict colonist structures rather than crafted from the starting blueprint set. As with other fragment-gated technology, the full blueprint becomes available once enough fragments have been scanned.

2020 Crafting
2121  
2222 The handheld Scanner is one of the earliest tools the player can build at the Fabricator. It is part of the starting crafting loop alongside basic survival gear, so most players have it in hand within the first minutes on Proteus. Because the live Early Access build is still being balanced, exact ingredient costs can shift between updates; in general the Scanner is a low-cost build relying on common early-game materials such as titanium and quartz plus a battery.

2424 Pairing with the Biosampler
2525  
2626 The Scanner works alongside the Biosampler as a dual-progression pair. The Scanner provides encyclopedic information about creatures and unlocks crafting blueprints, while the Biosampler extracts genetic material that feeds the DNA Adaptation System. Both tools reward exploration and creature interaction but feed different progression paths: the Scanner feeds crafting and resources, the Biosampler feeds genetic modification.

2828 Scanner Station Coverage
2929  
3030 The Scanner Station base module functions as a long-range radar from inside a powered base. Guides report a coverage radius of approximately 300 m around the station for pinpointing ore deposits, wrecks, and habitats, well beyond the range of the handheld Scanner alone. The station is built and powered the same way as other base modules, and is best placed near a region the player intends to sweep methodically.
