Boo Radar

The Boo Radar is a device made by Professor E. Gadd in Luigi's Mansion that tells you if a Boo is hiding somewhere in the area. The radar might detect a Boo, but it will either be a bomb or a ball resembling a Boo. It makes different colors to show if a Boo is nearby; blue means there are no Boos near you, yellow means there is a Boo somewhere, and red means you are right next to a Boo.
