The Multisensor is a tool that the player acquires early-on in the storyline of Endless Ocean: Blue World. It is used to detect treasures and what materials they are made out of, functioning like a metal detector, except that it can detect five categories of substance: , , , , and items that fit into . Metal items include the obvious: precious metals (like ingots of Gold, Silver, or even the legendary metal Orichalcum), jewelry, and coins. However, some paintings may have used paint that contained metals, so some paintings include a metal component as well.
