Blue Sea Systems builds marine meters and monitors that show what your electrical system is doing. Find Mini OLED gauges, M2 DC monitors, and full vessel system monitors here. Picking the Right Meter Start with what you want to watch. Mini OLED meters give a clear single readout for one value, such as DC voltage, amperage, tank level, or temperature, and fit a compact panel cutout. They come in standard and blue backlight versions to match your helm. For battery health, an M2 DC state of charge monitor tracks how much capacity you have left, which is far more useful than voltage alone on a house bank. Single Gauge or Full Monitor If you only need one or two readings,...

Blue Sea Systems builds marine meters and monitors that show what your electrical system is doing. Find Mini OLED gauges, M2 DC monitors, and full vessel system monitors here.
Start with what you want to watch. Mini OLED meters give a clear single readout for one value, such as DC voltage, amperage, tank level, or temperature, and fit a compact panel cutout. They come in standard and blue backlight versions to match your helm. For battery health, an M2 DC state of charge monitor tracks how much capacity you have left, which is far more useful than voltage alone on a house bank.
If you only need one or two readings, individual Mini OLED meters keep it simple and affordable. If you want a complete picture, the VSM 422 vessel system monitor and M2 series combine voltage, current, tank, and other data on one screen, reducing panel clutter. Confirm the meter shunt or sender requirements before ordering, since current and tank meters need the matching sensor to read correctly.
It tracks how much battery capacity you have left, which is more useful than voltage alone for managing a house bank on the water.
Yes. Many Mini OLED ammeters, voltmeters, and tank meters offer standard and blue backlight versions so you can match your helm panel.
For one or two readings, individual Mini OLED meters keep it simple. For a full picture on one screen, the VSM 422 or M2 series combine several readings.
Yes. Current meters need a shunt and tank meters need a compatible sender to read correctly. Confirm these requirements before ordering.
