You just walk towards the general direction of your throw and the TOBU application leads you directly to your disc. In addition, the Charge also beeps and flashes to give you the maximum opportunity to find it. TOBU discs also have a textured inside rim to help players get a better grip on the discs in any playing environment. The Charge has been designed from the beginning to be the most technologically advanced disc on the market."
