Lowrance 50 FT Ethernet Cable ETHEXT-50YL

Enhance Your Marine Network with Reliable Long-Range Connectivity

Connecting multiple marine electronics units across your vessel can be a challenge, especially when you need to span greater distances without compromising signal quality or reliability. This 50-foot Ethernet extension cable steps in as the perfect solution, engineered specifically for demanding boating conditions. Crafted to link Navico systems seamlessly via NEP-1 or NEP-2 expansion ports, it ensures smooth data transfer between fishfinders, chartplotters, and other onboard gear. Anglers and boaters alike appreciate how it maintains high-speed performance over extended runs, letting you position displays exactly where you need them—whether at the helm, on the console, or even in the cabin.

Built for the Harsh Realities of the Water

Marine environments throw everything at your gear: saltwater spray, constant vibrations from engines and waves, UV exposure, and chemical cleaners. This cable rises to the occasion with rugged construction that's moisture-resistant, solvent-proof, and designed for longevity. The tan outer jacket blends discreetly with most boat setups, while the 5-pin yellow connectors provide a secure, unmistakable fit for Lowrance Ethernet ports. No more worrying about frayed wires or dropped connections mid-fishing trip—it's tough enough to handle rough seas and repeated setups.

Seamless Compatibility Across Lowrance Ecosystems

Whether you're running a compact setup on a smaller craft or a full network on a larger offshore vessel, this cable integrates effortlessly. It's tailored for Lowrance units featuring the 5-pin yellow Ethernet connector, including popular series like HDS, Elite, Hook, and more within the Navico family. Pair it with NEP-1 or NEP-2 network expansion ports to create a robust Ethernet backbone. This setup shines for sharing sonar data, waypoints, and radar overlays across multiple screens, giving you a unified view of the water without latency issues common in shorter or inferior cables.

Installation Made Simple for DIY Boaters

Setting up your network doesn't require a marine electrician. Start by powering down all units, then plug one end into your primary display's Ethernet port and route the cable along secure paths—using cable ties or conduit to avoid snags. Connect the other end to the NEP expansion port, and you're networked. The 50-foot length offers flexibility for transom-to-tower runs or multi-station helm layouts. Pro tip: Keep runs under 100 meters total per segment to optimize performance, and test connections post-install with your unit's network diagnostics tool for peace of mind.

Unlock Peak Performance for Serious Anglers

Imagine casting lines while StructureScan overlays real-time sonar from a distant transducer, or tracking weather radar from the flybridge on your main plotter—all without glitches. This extension cable empowers that by supporting high-bandwidth data flows essential for advanced features like CHIRP sonar sharing and video feeds. Boaters report fewer network hiccups and easier expansions, making it a smart upgrade for anyone chasing trophy fish or navigating tricky inlets. Its reliability means more time fishing, less time troubleshooting.

Long-Term Value Through Superior Engineering

Lowrance's commitment to innovation shines here, with a design that prioritizes not just connectivity but endurance. Backed by decades of marine expertise, this cable helps future-proof your setup as you add new units. Regular users highlight its resistance to common failure points like connector corrosion, ensuring seasons of trouble-free service. Invest in quality cabling upfront, and watch your entire system perform at its best.
