The Orion Dye Marker is useful on both land and sea and creates a luminescent green area of up to 50 feet. A signaling dye marker is a perfect addition to your signal kit and also as an individual signal that can be affixed to PFD's and used on PWC's.
The Orion Survival Dye Marker comes in a 1 oz container with a lanyard. A bright orange air and watertight container makes it durable and easy to locate in an emergency.
