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.
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.
In Super INFINITY, Bulma invents a new Dragon Radar called, Super Dragon Radar. The Super Dragon Radar is created to help Bulma find the Super Dragon Balls on a larger scale. Sailor Mercury's Mercury Goggle had the same function as the Super Dragon Radar.
