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 one 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 spawn in underground wooden chests and wooden crates from Fishing.
