The Teleporter is a craftable gadget in CastleMiner Z, which was introduced in the 1.4 update. It looks like a red compass, but when you press the right trigger, you'll put down a point to teleport back to no matter how far you are from the point you placed down. You can instantly teleport to that point by pressing the left trigger while having the teleporter equipped, but you will lose the teleporter once you reached your destination and you need to make another one to replace it, otherwise, it functions as a locator.
