The Cell Phone, like other notable compound items (such as the Ankh Shield and Terra Blade), is an extremely powerful and helpful item to have on hand. Like a real-life cell phone, it can tell you the weather, the time, and where you are, among other things. Its usefulness however comes with a cost: its construction is highly time-consuming and some components are extremely difficult to find. This page will guide you on how to craft this item.

  • Gold WatchGold or Platinum WatchPlatinum Watch: Six varieties of watches can be crafted with any of the early pre-biome ores. To craft the GPS, you will need to obtain one of the highest-quality watches, which display the time to the nearest real-life second or in-game minute, as opposed to every minute or half minute. In order to craft the required watch, you must acquire 40 of either Gold Ore or Platinum Ore (only one type, as they cannot be mixed), and 3 of either Iron Ore or Lead Ore. Melt all of these into bars. Use the iron or lead to create a chain, and then go to a table and chair and assemble a Gold Watch or Platinum Watch.
  • Depth MeterDepth Meter: This is dropped by Cave Bats, Ice Bats and Jungle Bats. A Bat Statue can be used to easily obtain one.
  • CompassCompass: The compass can be obtained upon the death of certain monsters; Mother Slime, Piranha, Snow Flinx, Undead Viking, and Armored Viking.

Farming and Tips on getting the Cell Phone[]

To obtain these items, it may help to farm them. Make sure you have spare money to buy items from the Traveling Merchant.

All Items[]

  • The Enchanted Sundial can be used to skip a day, allowing you to reset the Angler's quest and make the Travelling Merchant to spawn more often.
    • You can also sleep in a Bed to make the time pass faster.
  • Place Water Candles and use a Battle Potion to increase the spawn rate of the enemies.
  • Place the right Torches and a Gnome to increase Luck so to increase the drop chance. You may also use a Ladybug and a Luck Potion.
  • Do loads of Fishing. Fishing will give you fish to craft Potions that can help you.
  • Defeat Skeletron in order to access the Dungeon enemies and drop the Tally Counter.
  • Exploring caves a lot helps get many of the items needed, as many of the items are obtained from underground enemies.

GPS[]

  • Watch: The Watch does not need farming, as it's craftable. You could use Spelunker Potions to help find the needed ore, or get the metal bars from fished Crates. The Extractinator might also be useful in getting the needed ores/bars.
  • Compass: You may use Piranha Statues, as they work well to farm Piranhas, who, in the Desktop version, Console version, and Mobile version, have a 2% chance of dropping a Compass.
  • Depth Meter: Bat Statues are useful for farming Bats. Bats have a 1% chance of dropping a Depth Meter.

Fish Finder[]

  • Do fish quests for the Angler every day, as the Fish Finder can be acquired randomly by completing quests for the Angler. The quests from the Angler reset at 4:30 a.m.
  • There is no realistic way to farm the Fish Finder aside from getting loads of Quest Fish and offering them to the Angler when he asks for one.

R.E.K 3000[]

  • Tally Counter: Enter a pre-Hardmode Dungeon with decent weapons, and start hunting.
  • Radar: If no surface chests are found with it, or your world was generated before 1.3, you can find it in Wooden Crates. Use Fishing Potions, Crate Potions, and Sonar Potions to increase your chances. You can also create new worlds and use them to packmule items including the Radar.
  • Lifeform Analyzer: Buy from Traveling Merchant (see above for tips).

Goblin Tech[]

  • Stopwatch: Buy from Traveling Merchant (see above for tips).
  • DPS Meter: Buy from Traveling Merchant (see above for tips).
  • Metal Detector: Create a long tunnel in an Ice biome. Run from end to end of the tunnel until a Lost Girl/Nymph spawns. A Lifeform Analyzer can also be used to find them more easily.
    • Don't defeat the Wall of Flesh without obtaining a Metal Detector. Lost Girls/Nymphs will be harder to find in Hardmode.
    • Farm the Nymph in Expert Mode, as it will drop the Metal Detector no matter what.
