The Dragon Radar is a device that can detect the location of the Dragon Balls. Its inventor Bulma uses the device in Dragon Ball Chapter 1, published on 20 November 1984.
Overview
The Dragon Radar was invented by Bulma at the age of sixteen. After she discovered the Two-Star Dragon Ball in her basement, she built the Dragon Radar and then used it to find the Five-Star Ball; then it led her to Son Goku and his Grandpa's Four-Star Ball, which is where the story of Dragon Ball begins.[1]
While the Dragon Radar was designed to detect Earth's Dragon Balls, Bulma is able to use it to locate the Namekian Dragon Balls when she travels to Planet Namek with Kuririn and Goku's son Gohan.[2] It is also able to detect the Ultimate Dragon Balls in Dragon Ball GT.[3]

The original Dragon Radar is unable to detect the Super Dragon Balls, but only because its range does not cover the entire universe, much less two universes. Bulma is able to build a "Super Dragon Radar" by increasing the original radar's sensitivity without any Super Dragon Balls on hand to work with, but even with increased range, the Super Dragon Radar cannot detect the Super Dragon Balls from Earth.[4] It is able to detect them when they travel to the Nameless Planet where all the balls are gathered together,[5] but the Super Dragon Radar has never been successfully used to search for the Super Dragon Balls.
Name

"Dragon Radar" (ドラゴンレーダー Doragon Rēdā) is directly transliterated from English to Japanese. It is unclear why Harmony Gold, Funimation (with their 1995 BLT dub), and Viz all chose to call it something else at one point: either "bleeper", in the case of the anime dubs, or "ball detector", in the case of the Viz manga. The term "ball detector" was used in Viz's original printing of chapter 1 in Part 1 #1 of their monthly comics, and this term persists even in 2019 printings of the Shonen Jump Graphic Novel version of Dragon Ball Tankōbon Volume 1, though it has been corrected in other editions including the VIZBIG edition and the 3-in-1 edition.
Variations
Various people other than Bulma have built their own "Dragon Radars", with varying levels of success...
