Lowrance ETHEXT50YL 50' Ethernet Cable

The Lowrance ETHEXT50YL 50' Ethernet Cable is a marine-grade networking solution designed for professional and recreational anglers who rely on Lowrance chartplotters and sonar systems. This extended-length cable bridges the gap between helm stations and network components, enabling reliable data transmission across larger vessels where standard cable lengths fall short. Built specifically for marine environments, it ensures stable connectivity for fish-finding electronics and GPS integration systems that demand continuous, uninterrupted signal flow.

The 50-foot length provides flexible installation options for boats ranging from center consoles to larger cabin cruisers, allowing technicians and boat owners to route cables through cable runs, behind panels, and across deck areas without signal degradation. Ethernet cabling in marine applications must withstand salt spray, UV exposure, and temperature fluctuations—this Lowrance cable is engineered to deliver consistent performance in harsh saltwater conditions. The robust construction and weatherproof connectors maintain impedance standards required for Gigabit Ethernet communication, supporting high-speed data transfer between networked sonar modules, transducers, and display units.

Network installers and boat builders benefit from this cable's compatibility with Lowrance's complete ecosystem of networked electronics, including HDS LIVE, HDS GEN3, and NavicoSonicHub systems. Installation is straightforward—simply connect between compatible Lowrance units using standard RJ45 connectors, and the cable's extended reach eliminates the need for multiple shorter segments or signal-compromising adapters. Whether you're upgrading a single system or building out multi-unit sonar arrays, the ETHEXT50YL delivers the range and reliability that modern marine electronics demand.
