Navigation Displays

Start With the Main Screen

The chartplotter or multi-function display usually sets the direction for the rest of the electronics system. Screen size, mounting style, chart support, sonar needs, radar compatibility, and network type all matter.

Chartplotters & MFDsMarine GPSChart CardsDisplay Mounts

System Planning

Build Around Compatibility

Displays, radar, transducers, AIS, radios, antennas, sensors, and digital gauges need to communicate correctly. Planning the system before buying helps avoid mismatched parts and extra installation work.

Search by device type, brand, screen size, network type, transducer style, chart region, or existing model number.

GPS

Navigate

GPS chartplotters, MFDs, chart cards, depth data, and route-planning tools help keep the boat oriented and on course.

AIS

See & Be Seen

Radar, AIS, VHF, antennas, and visibility tools support situational awareness in traffic, fog, rain, and night operation.

DATA

Connect the Helm

NMEA networks, sensors, gauges, transducers, speakers, and accessories bring useful vessel information to the places you need it.

Sonar, Sensors & Monitoring

Track What Matters Onboard

Bring depth, sonar, engine data, tank levels, battery status, wind, weather, alarms, and vessel sensor information into view with compatible electronics and accessories.

TransducersFishfindersTank SensorsWind Instruments

Networking & Accessories

Complete the Install Cleanly

A reliable electronics upgrade depends on the support pieces too: antenna mounts, data cables, power wiring, network tees, terminators, display covers, brackets, transducer hardware, speakers, and installation accessories.

Setup Help

Plan the Helm Before Ordering

Good electronics installations start with space, visibility, cable access, power protection, network layout, and future expansion. A little planning before checkout can save a lot of rework at the dash.

Choose the display firstPick the screen size, mounting location, chart support, sonar needs, and radar compatibility.
Confirm the networkCheck NMEA 2000, NMEA 0183, Ethernet, Wi-Fi, Bluetooth, sensor support, and engine-data needs.
Match the transducerChoose transom-mount, thru-hull, in-hull, CHIRP, side-scan, or traditional sonar based on hull and display compatibility.
Leave room to expandPlan for AIS, extra displays, cameras, radar, audio, monitoring, or digital switching that may be added later.

FAQ

Navigation & Electronics Questions

What should I choose first in a marine electronics upgrade?

Start with the main chartplotter or multi-function display. It usually determines compatible radar, sonar, transducers, networking, charts, and accessories.

Are chartplotters, radar, and transducers interchangeable?

Not always. Compatibility depends on brand, model, software, connector type, sonar technology, network type, and installation requirements.

What is NMEA 2000 used for?

NMEA 2000 allows compatible marine electronics to share data such as engine information, tank levels, GPS, heading, wind, depth, and other vessel information.

What should I check before buying a transducer?

Confirm display compatibility, sonar type, mounting style, hull material, deadrise, cable length, connector type, and whether the transducer location has clean water flow.
