Blue Sea Systems 1850 Vessel Systems Monitor provides real-time monitoring of your boat's electrical system, including battery voltage, current draw, AC voltage and current, tank levels, and bilge status. With alarms for high/low voltage, current, and tank levels, the 1850 helps you stay on top of your boat's electrical health and prevent problems before they occur. Its easy-to-read display and intuitive interface make it a breeze to use, even for those new to marine electrical systems.
