Brand Paths When You Know the System
Start with the system and installation need first: display, charting, sonar, radar, AIS, GPS position, mounting, wiring, networking, or replacement accessories. If you already know the brand, use the brand tiles below to narrow the search.
Mounting & Installation
Mount the Display, Radar, Camera, Antenna, and Network Cleanly
This collection includes a large amount of mounting support. Choose mounts around the equipment footprint, viewing angle, cable routing, structure, height, rake, and service access.
Navigation & Fishing
Choose Around How the Boat Is Used
A cruising boat may need charting, AIS display, radar support, route planning, and clear helm visibility. A fishing boat may need CHIRP, side imaging, live sonar support, split-screen control, waypoint speed, and a transducer matched to the hull.
Connected Helm
Build a System That Can Grow
Before choosing a display, think about radar, AIS, autopilot, cameras, engine data, NMEA 2000, Ethernet networking, chart cards, remote displays, and future transducer upgrades.
Position & Charts
Confirm GPS source, chart region, chart format, display size, and route-planning needs.
Sonar & Transducers
Match sonar support, connector style, transducer mount, hull type, and fishing style.
Network & Power
Check power cable, fuse needs, data cable, NMEA 2000, Ethernet, and accessory ports.

GPS & Navigation Electronics FAQ
Choosing GPS, Chartplotters, Displays, and Mounts
What should I check before buying a chartplotter?
Confirm screen size, dash space, chart region, sonar needs, transducer compatibility, power cable, networking, radar or AIS plans, and mount style.
Why are mounts and cables so important?
Many display problems come from poor mounting, unsupported cable routing, missing adapters, wrong network cables, or weak power connections. Match the mount and cables before installation.
Can one display handle GPS, sonar, radar, and AIS?
Many MFDs can, but compatibility depends on the display model, network type, radar family, AIS connection, transducer support, software, and required accessories.
How do I choose a transducer?
Match the transducer to the display, connector, sonar type, hull material, mounting style, depth range, and fishing use.
