The Metal Detector is an item introduced in 1.3. It is an accessory that tells the player the name of the most valuable ore type nearby. It detects most things a Spelunker Potion would highlight, so this may include pots, chests, and other treasures.

An example of the Metal Detector detecting something.


  • The Metal Detector function does not locate gems or Hellstone.
  • It assigns a high priority to Life Crystals, thus it's advisable for a player to break those in order to get the detector to scan for other things, such as Chests.
