The world's only
Second Generation ELT
Dukane Seacom’s Second-Generation Distress Tracking ELT-DT uses the latest medium Earth orbit search and rescue (MEOSAR) satellite constellation, providing near instantaneous global coverage. The Second-Generation ELT-DT (SGB) provides higher location accuracy, instantaneous receipt of distress signals, resists interference from other satellite signals, and offers improved performance in severe weather.
Developed using state-of-the art digital technology, the Dukane Seacom SGB is designed for network growth and future enhancements of the MEOSAR constellation for decades to come.
And the world's most reliable underwater locator beacons.
Dukane Seacom’s Underwater Locator Beacons (ULBs) are trusted around the world for their unmatched reliability and performance in the most critical recovery operations. Designed to activate automatically upon immersion in water, these beacons emit a high-frequency acoustic signal that can be detected up to several kilometers away—giving search and recovery teams a precise starting point even in the harshest underwater environments.
