Dragon Radar

The Dragon Radar was built by Bulma and is used to find the location of the Dragon Balls whether they're moving, not moving, under water, anywhere that they might be the Dragon Radar can find them. It has a single button on top, it is used to turn it on or off as well as zooming in on the Dragon Ball or zooming out. This is not used to find the Dragons even though its called a Dragon Radar. In Dragonball GT they use one of these to find the Black Star Dragon Balls around the universe but it is later eaten by a friend they find along the way. After Giru eats the Dragon Radar he becomes the Dragon Radar and helps them continue finding the balls.
