An Itemfinder is an item that is used to locate hidden PokéLoot chests. When used (right-clicked while in hand), it will show the direction of the nearest hidden PokéLoot chest if there is one within range. The maximum distance that can be detected is 35 blocks away. It will only detect hidden chests; visible chests will not be detected.
It is crafted using two diamonds in the top corners, three gold ingots at the top in the middle and on the sides, a piece of redstone in the center, two aluminium plates at the bottom on the sides and a glass pane in the middle.
