The Flame Radar gives the user the ability to see through invisible attacks by thinly spreading the user's Flame over a wide area and using the vibrations to detect whatever enters the area.
This ability allows the user to counter illusions by using it to sense where the actual object is, and then act accordingly. While Hibari uses his Ring's Flame for this technique, Yamamoto uses the Rain Flames from Kojirou's wings.
