Larger size 80g sachet

Marine dye marker used for daytime emergency distress signalling and search and rescue marking.


A person in distress scatters the dye marker 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.


Ideal for boating, it is also a piece of extra safety equipment for windsurfing, diving and snorkelling.


Sold in a sealed sachet with fastening lanyard.
