Sea Dye Marker

The Presto Dyechem MIL-S-17980D Sea Dye Marker is a lifesaving device used for sea rescue. This product is procured by the United States armed services for use on all military aircraft and vessels conforming to MIL-S-17980D specifications. The marker is also purchased by boat owners for additional protection in case of emergencies.

The Presto Dyechem MIL-S-17980D Sea Dye Marker contains a fluorescent green dye that spreads over the surface of the water so as to increase visibility for a rescue pilot to see. The marker can easily be placed in a life vest pocket or life raft safety kits.

The bright green pattern on the water can be seen for a mile or more and lasts for 30 to 40 minutes. Wind and the choppiness of the water will affect the shape of the pattern.

A field test study was done by Powerboat Reports in its October 1995 issue. Flares, steamers, mirrors and smoke flares were tested, as well as the dye marker. Powerboat judged the Presto Dyechem MIL-S-17980D Sea Dye Marker was the most effective tool for sea rescue.
