Shop Network Sensors at West Marine

If you’re outfitting a multifunction display (MFD) with advanced capabilities, West Marine offers a broad range of network sensors to enhance navigation, safety, and functionality. These include GPS antennas, heading sensors, marine cameras, satellite weather receivers, and more. These sensors integrate with your MFD to deliver real-time data across multiple systems, turning your helm into a fully connected control center.

GPS Positioning Sensors

External GPS sensors provide your MFD with precise positioning data. While some displays have built-in GPS, adding an external antenna improves accuracy and is ideal when the MFD is mounted under a hardtop or in a lower cabin space.

Heading Sensors for Autopilot Accuracy

GPS heading sensors go beyond basic positioning by tracking your vessel’s orientation. This data is critical for autopilots, radar overlays, and AR navigation features. The Raymarine MSC™ 10, for example, enhances heading precision even at low speeds.

Marine Cameras and Surveillance

Video cameras can be integrated with MFDs to improve situational awareness, monitor blind spots, assist in docking, or increase onboard security. Solutions like Raymarine’s CAM210 AR Pack combine visual feeds with augmented data for enhanced perception on the water.

Sonar and Fishfinding Modules

Sonar modules connect directly to your MFD and display underwater contours, fish targets, and structure. These plug-and-play modules allow for system expansion without upgrading your entire MFD unit.

Weather Integration with Satellite Modules

The SiriusXM® WM-4 module delivers up-to-date marine forecasts, wind overlays, sea surface temps, and weather radar via satellite, all visible directly on your compatible MFD display.

AIS and Collision Avoidance Sensors

AIS transceivers enhance safety by displaying real-time data on nearby vessels—including heading, speed, and identity—helping you make informed decisions in high-traffic zones.

Thermal Imaging for Night Operations

Thermal sensors and cameras provide night vision and heat signature detection, offering visibility in low-light or foggy conditions. These sensors interface directly with MFDs for navigational awareness after dark.

Network Sensors FAQ

Network sensors are external devices that connect to a multifunction display (MFD) to expand its features. They include GPS receivers, heading sensors, radar, sonar, cameras, and more—each providing specific data for navigation, fishing, and safety.

Not always. Some MFDs include built-in GPS receivers. However, external GPS sensors often provide stronger signal accuracy and are useful if your MFD is mounted below deck or obstructed from the sky.

While a GPS receiver shows where you are, a GPS heading sensor shows the direction your boat is pointing. This is especially helpful when moving slowly or for systems like autopilots that rely on accurate heading information.

Only if the MFD supports video input, such as IP camera or analog feeds. Check the specs of your MFD model to confirm compatibility with marine cameras before purchasing.

No. Sensor compatibility depends on the manufacturer and the network protocol used (NMEA 2000, Ethernet, proprietary connections). It’s best to match sensors with the same brand or consult compatibility charts before purchase.

Network sensors connect via NMEA 2000, Ethernet, USB, or proprietary plugs, depending on the brand and function. Always review the sensor's requirements and your MFD's available ports.

Yes. Thermal cameras can be connected to compatible MFDs to provide infrared imaging for night navigation and man-overboard detection. Ensure your MFD supports this feature before adding a thermal sensor.

Weather modules, like SiriusXM® units, deliver real-time weather radar, storm alerts, sea surface temps, and forecast data to your MFD so you can plan routes safely and avoid severe conditions.

Yes, if you have a standalone AIS receiver or transceiver connected to your MFD. However, many AIS units also combine with VHF radios, which can simplify your setup and save space at the helm.

Some sensors are plug-and-play, while others require precise mounting, power connections, or calibration. If you’re unsure, West Marine can assist with guidance or recommend a professional installer near you.
