K8ebands allows the adult to set a perimeter that allows their children to be at a safe distance while still allowing the child freedom. K8ebands will alert the adult if the child leaves the safety perimeter. The child band is waterproof with a water sensor that alerts the adult should the child be submerged into water. There is a built-in breakaway feature on the child band. We also designed a special locking system that allows easy prevention of the child removing the band.
