A new life saving device made by Norsa Performance has been released for people to use. It is a self propelled buoy that can fly out over the water to save people and is quote “It looks like about the quickest way we can imagine to get a piece of lifesaving gear out to a distressed person in the water.” The remote control is a thumb controller like you would see on an Xbox controller and gives a very smooth way to control it.It would also be useful on big ships instead of deploying a rescue boat. On big ships as well they hope to have it deploy automatically and find the person with a special GPS locator.
