Garmin BlueNet™ Marine Network Cable - 50'

The Garmin BlueNet™ Marine Network Cable – 50' is purpose-built for serious boaters who demand reliable integration across modern marine electronics systems. Whether you're networking chartplotters, autopilots, transducers, or other Garmin-compatible devices aboard your fishing boat or cruiser, this marine network cable ensures clean data transmission and system redundancy without compromise. At 50 feet in length, it spans larger vessels and complex helm layouts with enough slack to route through cabins and cable trays—critical for installation flexibility on anything from center consoles to offshore sportfishers.

Garmin's BlueNet™ standard employs high-quality shielded cabling that resists electromagnetic interference—a real-world necessity on the water where VHF radios, GPS systems, and engine electronics operate in close proximity. The cable's marine-grade construction handles saltwater exposure, UV sunlight, and temperature swings without signal degradation, ensuring your network maintains integrity season after season. Unlike consumer-grade networking solutions, BlueNet™ cables are tested to withstand the vibration, moisture, and corrosion found in true marine environments, protecting your investment in integrated electronics.

This 50-foot run works best for larger vessels or complex multi-station installations where helm visibility and autopilot redundancy demand networked electronics across separate compartments. It's compatible with all modern Garmin marine systems that support BlueNet™ networking—including GPSMAP, ECHOMAP, and networked sounder units—making it the go-to choice for retrofit upgrades or new builds. Professional installers and DIY boat owners alike trust Garmin's specifications for permanent installation, whether you're running cable through center console hardtops, cabin soles, or mast steps on sailboats.
