"A tool Bulma created to find the Super Dragon Balls, which were created in Year 41 of the Divine Calendar by the Dragon God Zalama. Each one has a diameter of 37,196.22041km."
The Super Dragon Radar (超ドラゴンレーダー, Sūpā Doragon Rēdā) is an improved version of the Dragon Radar that's less sensitive, which can help locate the Super Dragon Balls in a much larger area in the universe.
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.
Five days later, Bulma attends the Universe 6 and Universe 7 tournament and she takes the Super Dragon Radar to the Nameless Planet look for the Super Dragon Ball after the tournament. After the tournament, Bulma uses it to find the final Super Dragon Ball and she detects seven balls, instead of the six Champa found. Whis destroys the Nameless Planet and it turns out to be the Four-Star Super Dragon Ball.
Video Game Appearances
The Super Dragon Radar appears an equipable accessory item in Dragon Ball Xenoverse 2, however the item itself is purely cosmetic. It can occasionally found as near the Dragon Ball Pedestal in Conton City as a random item drop.
