The original standard for flare alternatives was developed by the US Coast Guard in 1979 - long before powerful LEDs were even available. In 2014, Sirius Signal developed the first USCG approved electronic visual distress signal (eVDSD/s). Today, Sirius Signal delivers the latest in boating safety technology with the C-1002. The C-1002 offers both an infrared (IR) and two-color SOS distress signal. Sirius Signal SOS eVDSD/s are the only products to have IR LEDs (C-1002 & C-1004) and Sirius Signal is the only manufacturer in the world to produce two-color RTCM 13200.0 standard. The flashing two-color (Red-Orange/Cyan/Red-Orange) signal is designed to more easily be seen against busy background lights along the shoreline - its also 5x brighter than any single white color eVDSD. The super-bright LEDs deliver 50 candelas in an omnidirectional pattern, allowing you to be seen from any direction for up to 10 nautical miles. The included 10-year Lithium CR123 batteries far outlast pyrotechnic flares, which must be replaced every 3 years. Sirius Signal warranties and provides parts and service for every model. The C-1002 also offers built-in Bluetooth allowing you to connect your light to the optional Afloat Plan Home app. Using the app, remotely activate the C-1002 and check the battery status. Keep your signal within easy reach with this secure mount that easily creates a vacuum seal on any flat surface. Designed to withstand life on the water, the CSM-1000 mount can be used for storage as well as displaying your eVDSD in a prominent location during an emergency. The C-1002 is approved for use by the US Coast Guard, Transport Canada, and Marine and Safety Tasmania (MAST). Approved by Transport Canada to be used as nighttime visual distress signal on pleasure craft instead of flares when carried with an approved smoke signal, Nov 2021
