Lowrance N2KEXT-15RD Extension 15' NMEA 2000 Cable

The Lowrance N2KEXT-15RD Extension 15' NMEA 2000 Cable is the professional angler's solution for expanding network reach on vessels where transducers, GPS modules, and multifunction displays sit far apart. Whether you're running a center console, trawler, or extended cabin cruiser, this extension cable bridges the gap between networked electronics without sacrificing signal integrity or forcing costly equipment relocations. Built to the NMEA 2000 standard, it ensures your fish finder, sounder, and navigation instruments communicate seamlessly—critical when you're miles offshore and your electronics are your lifeline.

The 15-foot length gives you the flexibility to position your Lowrance sounder and transducer assembly wherever water column visibility and drag profiles demand, while keeping your network backbone intact. NMEA 2000 cables carry both power and data over a single, ruggedized connector, eliminating the tangle of separate power and signal wires that plague older installations. The N2KEXT-15RD is engineered to resist salt-spray corrosion, UV degradation, and mechanical abrasion—conditions every serious boater encounters on the water. Its rated construction ensures voltage stability across longer runs, preventing the data dropouts and display lag that can cost you trophy fish or safe navigation.

This extension cable is indispensable for anglers upgrading legacy systems, installing dual-frequency transducers at the gunwale, or integrating autopilot and radar modules at the helm station. Installation is straightforward—simply daisy-chain it between any two NMEA 2000 devices using the standard drop-cable connectors. Weighing only 0.4 pounds, the N2KEXT-15RD adds virtually no mass to your rigging while delivering the reach and reliability you need whether you're chasing stripers on a river or working structure hundreds of miles at sea.
