Specification Sheet
Product Manual






This redesigned workhorse utilizes patented, proprietary electronics package for faster, more stable 406 MHz transmissions to low-earth orbiting LEOSAR satellites. In an emergency, your registered, digitally-coded distress message is broadcast via a powerful 6-watt, 406 MHz signal (typically within 1 hour). An integrated 121.5 MHz homing signal then guides local Search and Rescue efforts.
 
Upgrade to GPS positioning with the optional GPS interface cable (sold separately). This connects the Satellite3 406™ to your vessel’s GPS receiver to continuously update and store precise position data. GPS positioning provides SAR notification typically within 2–15 minutes.
 
The automatic category I Sea Shelter3™ bracket is fully enclosed and is made of high density, UV-stabilized polyethylene for years of extreme abuse, while the manual category II QuickDraw™ has a low profile and is easy to rail mount or secure on deck.
 
Send I’M OK messages with optional 406Link.com non-emergency messaging service.
