Locating people in the ocean is very difficult and requires a great deal of time, especially at night. Time is, however, critical in rescue missions. Therefore there are rescue rings equipped with flash lights to show the position of a person, but their efficiency is under discussion because waves or obstacles like sea rocks can block the light source.
LazeRing is an innovative design that benefits from 3 laser devices powered by a LI ion battery. Since seeing a line of light is easier than seeing a spotlight, rescue staff in helicopters or boats may locate the person rapidly by following the laser light line.
