Designed to completely replace traditional pyrotechnic flares, this LED visual distress signal device lasts up to 60 hours. Based on U.S. Coast Guard requirements, the device flashes in SOS sequence and is visible for up to 10 nautical miles. The LED flare floats and can be handheld, tethered or lifted upward. Paired with a daytime distress signal flag to meet all Coast Guard requirements for day and night use, it operates using three standard C batteries.
