Radar

The Radar is an item that detects nearby enemies when equipped or left in one's inventory. It is one of the three parts necessary to make the R.E.K. 3000, with the others being the Lifeform Analyzer, and the Tally Counter. If a player is within approximately 20 blocks of another player on the same team who has a Radar, that player can also see the enemies detected by their Radar.

It can be obtained from looting surface chests. Or crates by fishing.
