Grav Trap (Subnautica)

This seems new

This article contains information that is updated for the latest Experimental Version of Subnautica. Players using stable mode may find this information inaccurate.

The Grav Trap is a deployable crafted using the Fabricator. The Grav Trap can only be crafted after its blueprint has been acquired by scanning its fragments.

It attracts up to twelve small objects and Fauna to itself. Its main uses are to ensnare fast-moving fish, like the Peeper, for the Player to catch more easily and to collect materials broken free with the Prawn Suit Drill Arm.

The Grav Trap can be placed in an environment with an abundance of fish to act as a fish farm, although a Alien Containment tank is more reliable.

Usage

The Grav Trap takes up 2x2 item slots in the player's Inventory. Although it requires a Battery to be built, it does not use energy. The Grav Trap attracts fish and any small item that can be picked up manually within reach. Plant material, such as Creepvine Seed Clusters, are the exception. It is best to place it on the ocean floor.

It is suggested to remove the objects caught by the Grav Trap before picking up the sphere. If the player is in the open ocean, currents may send the objects 30 meters or more away if the player picks up the Grav Trap with objects still attached it.

Using the Stasis Rifle or Propulsion Cannon is more effective for hunting than the Grav Trap.
