What's in the box.
Boat Monitor BM-50 Standard
Best for
30ft+ sailing yachts, motor yachts, and most modern leisure boats.
BM-50 Standard is our most popular Boat Monitor, featuring built-in 4G connectivity, GPS tracking, battery monitoring, NMEA 2000 integration, support for external GPS antennas, and wired and wireless sensors. With 1 built-in relay for basic digital switching, it offers the ideal balance of onboard visibility, expandability, and everyday simplicity.
NMEA 2000 Drop Cable
A NMEA 2000 drop cable is included to connect the Boat Monitor directly to your vessel’s NMEA 2000 network.
PLUG INTO WHAT’S ALREADY THERE.
Digital Engine Watch can do more than monitor your boat. Through BM-50 Standard, Sentinel can become part of a broader onboard ecosystem, enabling remote switching and integration with compatible digital switching platforms.
Simple digital switching — out of the box
BM-50 Standard includes 1 built-in Remote Control Output, allowing simple remote switching directly from the Sentinel app. You can control selected onboard equipment such as:
- Lighting
- Refrigerators
- Pumps
- Other supported onboard systems
Additional Remote Control Outputs can be added through Sentinel Hub.
Disclaimer
Some onboard equipment may require additional interface hardware depending on the system configuration and power requirements.
Integrate with existing systems
Sentinel can integrate with compatible digital switching and onboard monitoring systems such as CZone, EmpirBus, and Simarine — allowing deeper onboard visibility and expanded control possibilities through existing onboard infrastructure.
This means Digital Engine Watch can become part of a larger connected boating ecosystem rather than operating as a standalone monitoring device.
Disclaimer
Some integrations may require additional third-party subscriptions, hardware, certifications, or compatibility verification.
