Seamark Dye Marker
Marine dye marker is used for daytime emergency distress signalling and search and rescue marking.
A person in distress scatters Seamark on the water when a potential rescue vessel or aircraft appears. It spreads as a brilliant spotting mark, clearly visible as a distress signal for up to an hour, and in good visibility can be seen by aircraft over 10 km away.
As well as for personal use, it is a good addition to a Grab Bag and is also ideal for emergency use when windsurfing, diving and snorkeling.
