The Dragon Radar (also called Bleeper in some dubs) was a tracking device designed, built and patented by Bulma to help locate Dragon Balls. This made finding the Dragon Balls more efficient compared to conventional methods. Dragon Balls emit a faint electromagnetic pulse[1], which the Radar can detect. It then points arrows in the directions of nearby Dragon Balls. Pressing the button on the top can cause the view to zoom out and show more and more of the planet (it is never explained what is necessary to do to zoom in, or even turn the radar off entirely).
In Dragon Ball, Goku accidentally broke the Dragon Radar while fighting General Blue. During his search for a capable mind to fix the Reader, Goku met Arale from Dr. Slump, who asked her father/creator Senbei Norimaki to fix it, but Senbei couldn't make heads nor tails of it. Turbo, her baby genius "brother", fixed it while nobody else was looking. The Radar is used frequently by Goku and his friends in Dragon Ball and Dragon Ball Z, but in Dragon Ball GT the Dragon Reader is assimilated by the robot Giru, giving him the ability to find the Dragon Balls for Goku and the others.
During their hunt for the Dragon Balls, the Red Ribbon Army had their own version of the Dragon Radar, but it was rather primitive and could only give a general idea of where the Dragon Balls were. Emperor Pilaf eventually built his own, superior version of the Dragon Radar; shaped like a globe and installed in his floating airship, it was able to show the Dragon Balls' exact location on the planet. The Dragon Radar is also frequently used in the Namek Saga and throughout the remainder of the series.
[edit] Trivia
- There is an iPhone/iPod Touch application that emulates the Dragon Radar. It's named DReader
