Visualizer

The Visualizer is a pair of glasses that allows the wearer to see EM waves. Geo Stelar is the only known wearer of the Visualiser. In the games and anime, it once belonged to his father and was given to him by Aaron Boreal. Geo uses it to find wave holes and other ways to get past obstacles in the games, and whilst using these he can communicate with nearby Mr. Hertzes and Navis.

In the anime, the Visualizer technology is also used in the development of the Star Carrier, which allows users of the Star Carrier to see EM Waves, and consequentially, any EM beings and viruses. This has been proven handy when used in conjunction with one of the virus deletion tools employed by the Satella Police.
