Super Dragon Radar

The Super Dragon Radar (スーパードラゴンレーダー, Sūpā Doragon Rēdā) is an improved version of the Dragon Radar that's less sensitive.

Dragon Ball Super
Bulma invents a new Dragon Radar called, Super Dragon Radar. The Super Dragon Radar is created to help Bulma find the final Super Dragon Ball on a larger scale. Bulma cannot use the Super Dragon Radar on Earth because the Earth is on the edge of the universe and so they need to get to the center to be able to find the last Super Dragon Ball. Bulma gets help from Jaco to accomplish this mission.
