The Pathfinder Tool is a tool that the player can use to find their way back during cave exploration. It is crafted using the Fabricator.

The Pathfinder Tool consumes Energy from a Battery when placing pathfinder discs. The Pathfinder Tool uses 10 energy per 20 discs, making it able to dispense up to 200 discs (10 maximum uses) on a single full Battery charge (or 5 times that using an Ion Battery). The player can replace the Pathfinder Tool's Battery by pressing R.


The player can press RMB to eject a disk from the Pathfinder Tool. The disc will emit a blue holographic projection. The first disk will emit a sphere; the other 19 disks will emit an arrowhead, which will point at the next disk in the line. Every five seconds, the first disk will pulse green, and the next one will pulse green after a half-second, and continue in this manner down the line of arrowheads.

The player can press F to remove the disks from the environment. The Pathfinder Tool works both in and out of water.

  • The Pathfinder Tool was in the original Subnautica where it was first implemented as the "Dive Reel," having a slightly different function. A dart-like "anchor" could be attached to a rock face or the seabed, connecting to a rope that was intended to help the player find their way back to where they had placed the hook. Due to clipping issues and difficulties in following the rope, this was reworked into its current form.
