The Dual PML (Personnel Marker Light) has two ChemLights that operate in warm (above 50°) or cold water (below 50°).

Designed to be lightweight, waterproof, and buoyant, the PML is the perfect emergency locator for rescue-at-sea. The Dual PML easily attaches to PFD’s and immersion suits. When the protective sleeve is removed, 360° of reliable light is visible up to 1 nautical mile and up to 3 miles by air. Recommended for off shore and workboat personnel.
