Capable of detecting all the Dragonballs on earth. The front piece has a display that shows where and how far away you are from the nearest Dragonball(s). You can also set the range as to how much area you want to cover. The top button is used as an on and off switch. 

When Gohan went to Satan city to attend school, he would fight crime whenever he had a chance. He was concerned however, about his identity when he did this. He asked Bulma to create a suit to hide his identity. This suit contains a top garment, a belt, boots and a protective helmet. 

This watch was worn by Gohan so he can change his gear on the fly. Wearing his normal street cloths, Gohan can press a few buttons to transform into Great Saiyan man. 

This fighting jacket imitates the old design battle armor that Vegita wore at the end of the Freeza saga. It only covers the chest and back area.  

An imitation of Dr. Gero's emergency stop controller, this is a device that can send radio signals to set off self destruct mechanisms in Android 17 and 18. 

In the alternate future, Bulma invented a time machine so that Trunks can go to the past to help correct Earth's current fate. The time machine takes about 8 months to recharge for a round trip. The reason why it takes so long to recharge is because of the technology available at the time (the western capital was destroyed by the Androids, where Capsule Corporation is located). Cell also used this to return to the past to find the androids.

This is a trick candy that when eaten, will cause the person who eats it to have severe stomach cramps and diarrhea when they hear the words "pee pee" (it is shown that Bulma was whistling in the Manga translated by VIZ) It was given to Oolong by Bulma in order to make him obey what she commands.
