The Float-On delivers rapid location recovery by leveraging GPS coordinates and bearing data, guiding responders straight to the person or object in the water. Its edge-lit lighting and high-visibility orange housing enhance visibility in low-light conditions, while the water-activated strobe provides a long-lasting signal even in rough seas. Built to withstand marine environments, it stays functional when attached to people or gear and scales from a single-user setup to a fleet, thanks to extenders, base stations, and guardian engines. For lone boaters, the free OLAS app offers Solo mode and emergency SMS notifications to keep contacts informed in real time.
