The Depth Meter is an informational accessory that displays the player's depth. Depth is relative to the boundary between the Surface and Underground layers, which has a depth of 0 and is displayed as "Level". The display shows the vertical distance to this line and the name of the current layer. Depth is always measured at the level of the player's feet.

The Depth Meter has a (Desktop, Console and Mobile versions) 1/100 (1%) / (Old-gen console and 3DS versions) 1/200 (0.5%) chance of being dropped by Cave Bats, Jungle Bats, Ice Bats, Giant Bats, and Spore Bats(Desktop, Console and Mobile versions). Furthermore, it has a 1/80 (1.25%) chance of being dropped from Crawdads(Desktop, Console and Mobile versions), Giant Shellies(Desktop, Console and Mobile versions), and Salamanders(Desktop, Console and Mobile versions). In the Old-gen console version Old-gen console version, the Depth Meter may also be crafted.

The Depth Meter is one of the three parts necessary to make the GPS, with the others being the Compass and the Gold Watch or Platinum Watch, and as such is a required ingredient in crafting the Shellphone(Desktop, Console and Mobile versions).

  • (Desktop, Console and Mobile versions) Unlike most accessories, informational accessories such as the Depth Meter do not need to be equipped in an accessory slot. The Depth Meter may be carried in the player's inventory without loss of functionality, unless equipped to a social slot. Additionally, the info it provides will be shared with players of the same team in multiplayer that are within 50 tiles. Keep in mind modifiers will no longer apply to the player when not equipped.
  • The Depth Meter will not work if equipped in a vanity slot.
  • Cave Bats spawned by a Bat Statue only have a 1/500 (0.2%) chance of dropping a Depth Meter.


  • The Depth Meter is useful for finding biomes that are generated at specific elevation ranges, such as Floating Islands, the Underground Jungle, and the Underworld. It also helps with locating the first three tiers of Hardmode ores.
  • The Depth Meter can be used to avoid spawning Dungeon Guardians by staying above 0 depth.
  • Old-gen console version The Depth Meter can only be crafted with Copper, Silver, and Gold, so it might be inevitable to create another world. However, if the world count is full, you can jump through worlds, although you can instead get gold by using the Extractinator.
