 Obtained from Classic Expert Master
The **Depth Meter** is an informational accessory that displays the player's depth. It is required to craft the GPS, which can then be used to craft the PDA and the Cell Phone. The Depth Meter is dropped by Cave Bats, Giant Bats, Jungle Bats, Spore Bats, and Ice Bats, with a chance of ~~1\*~~1/100 (1%)  / ~~0.5\*~~1/200 (0.5%) . On the PC, Console, Mobile, Old Chinese, tModLoader, and tModLoader Legacy versions, it also drops from Salamanders, Giant Shellys, and Crawdads, with a chance of ~~1.25\*~~1/80 (1.25%). In the Old-gen console version, the Depth Meter may also be crafted.

* On the PC version, Console version, Mobile version, Old Chinese version, tModLoader version, and tModLoader 1.3-Legacy version, depth is measured in feet, with one tile equaling two feet.
* On the Old-gen console version, depth is measured in meters, with two tiles equaling one meter.
* On the Windows Phone version and Nintendo 3DSversion, depth is not measured, and the only benefits the accessory grants are from its modifiers.

Depth is measured 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.

## Notes

* 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 nearby players of the same team in multiplayer. Keep in mind modifiers will no longer apply to the player when not equipped.
* Depth is measured at the level of the player's feet.
* The Depth Meter will not work if equipped in a vanity slot.
* Cave Bats spawned by a Bat Statue have a ~~0.2\*~~1/500 (0.2%) chance of dropping a Depth Meter.

## Tips

* 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.
* 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.
