BLUE SEA SYSTEMS MONITOR. THERE ARE SOME ITEMS MISSING FROM THIS PACKAGE, LOOKS TO BE AN OPEN BOX RETURN SO ONLY COMES WITH HEAD UNIT, SURFACE MOUNT BEZEL, MOUNT GASKET, SHUNT, QUICK START GUIDE, AND INSTALLATION/CONFIGURATION MANUAL. EVERYTHING MISSING LOOKS TO BE AVAILIBLE FROM THE MANUFACTURER SO IT'S UP TO YOU TO LOCATE/PROCURE WHAT ELSE IS REQUIRED FOR COMPLETE OPERATION.

THESE ITEMS ARE FROM A LOCAL MARINE SUPPLY STORE THAT WENT OUT OF BUSINESS. I HAVE INCLUDED ALL INFORMATION I FOUND ON THE PACKAGING THAT SEEMS RELEVANT, SO KNOW WHAT YOU NEED!
