The number of coastal deaths is on the rise; 49 people have died over the last five years in the UK alone. Nationally, the number of deaths has reached a five-year high. The main issue is time. It takes too long for incidents to be reported and for the Coast Guard to reach a casualty, by which point it can be too late. Coastal eradicates this ambiguity; a discreet armband which can be worn by coastal sports enthusiasts and be activated instantly if the wearer finds themselves stranded or caught in a riptide. Once triggered, a flotation aid is released and a GPS location alert is sent directly to the Coast Guard for immediate rescue.
