Extend your marine electronics network with confidence using this robust 25-foot Ethernet cable designed specifically for Lowrance systems. Whether you're rigging up a multi-station setup on your boat or need to bridge the gap between your chartplotter and expansion port, this cable delivers seamless data sharing for sonar readings, GPS waypoints, and chart updates across your gear. Anglers and boaters alike rely on it to keep their setups connected without signal dropouts, even in rough waters.

Unlock Seamless Networking on the Water

In the world of marine navigation, a reliable connection between your fishfinder, chartplotter, and accessories can make all the difference during a long day on the water. This Ethernet extension cable steps in where shorter leads fall short, allowing you to position your displays and sensors exactly where you need them. Imagine sharing real-time structure scans or StructureScan data from one unit to another without cluttering your helm— that's the freedom this cable provides.

Built to handle the marine environment's toughest challenges, it resists corrosion, UV exposure, and constant vibration from engine hum and waves. No more fumbling with makeshift extensions that compromise your data flow; this is the genuine article engineered for Lowrance's high-performance ecosystem.

Effortless Integration with Your Lowrance Setup

One of the standout advantages is its plug-and-play compatibility. Featuring 5-pin connectors that mate perfectly with Navico systems, it works directly with NEP-1 or NEP-2 expansion ports. This means quick swaps or expansions without custom adapters or splicing—saving you time at the dock or mid-trip.

• Supports data-heavy networks for sharing waypoints, routes, and sonar overlays
• Ideal for boats with multiple helm stations or spread-out transducer mounts
• Maintains gigabit speeds for lag-free performance

Simple Installation Tips for Peak Performance

Getting this cable up and running is straightforward, even for weekend warriors:

1. Power down all units to avoid shorts.
2. Route the cable along existing wiring runs or secure with marine-grade zip ties.
3. Plug into the Ethernet port on your primary unit and the NEP expansion port.
4. Power up and verify network detection in your Lowrance menu—look for linked units.
5. Test data sharing by pinging sonar or waypoints between screens.

Pro tip: Keep runs away from high-voltage lines to minimize interference, and use cable glands for watertight deck passes.

Built to Last Through Seasons of Fishing

Lowrance's reputation for rugged gear shines here. TPE jacket shrugs off saltwater spray, and the twisted-pair construction fights electromagnetic noise from motors and radios. Pair it with proper strain relief, and it'll outlast your current electronics. Backed by a manufacturer's limited warranty, it's peace of mind for serious setups.
