C-1003 SOS Distress Light, Flag & Whistle, NEW!

Marine Distress signalling kit. NO MORE FLARES! Complete compliance kit! Fulfills USCG Night, Day, and audible distress signal requirements. Batteries included!

Our new and improved eVDSD SOS C-1003 Beacon is redesigned from our Original Alternative to Pyrotechnic Flares, the wildly successful model C-1001. Can be hand-held, hoisted aloft, tethered to a life ring, or thrown in the water to mark overboard crew.

Our optical design provides an omnidirectional light display for surface rescue craft and a vertical beam visible to aircraft flying overhead.  It  is visible up to 10 nautical miles, and the SOS C-1003’s beam lasts for hours compared to the minutes-long lifespan of traditional pyrotechnic distress flares. Powered by a high-performance, programmable microprocessor controlling an SOS flash pattern signal flashed through an even brighter and more potent LED, our Sirius Signal SOS C-1003 model is both family-safe and easy to use.

Fulfills carriage of all Coast Guard Compliant Visual Distress Signal (VDS) requirements (46 CFR 175.130) for recreational marine vessels 16 FT AND OVER signals when combined with our included Distress Flag. A quality Marine whistle is included to fulfill USCG audible signal requirements.
