Lowrance NDC-4 NMEA-0183 Cable

The Lowrance NDC-4 NMEA-0183 Cable is the backbone of reliable fish finder connectivity on the water. Designed for anglers and boaters running Lowrance Elite and Mark series units, this 4-pin cable bridges your chartplotter or fishfinder to other networked marine electronics—enabling real-time data sharing between GPS, sounder, and autopilot systems. If you're serious about integrated navigation and sonar performance, this cable is non-negotiable for multi-device setups.

Built to NMEA-0183 standard, the cable uses a 4-pin connector configuration that allows bidirectional communication between Lowrance marine electronics. NMEA-0183 is the marine industry's open protocol for sensor and equipment interoperability—meaning your Lowrance unit can transmit heading, position, and sonar data to compatible autopilots, GPS units, and external displays, while receiving inputs in return. The lightweight construction (1 lb) and durable connector design withstand saltwater spray, UV exposure, and the thermal cycling common to open-water use.

This cable is essential for anglers integrating Lowrance Elite or Mark series units into a networked electronics suite—whether you're linking a sounder to a dedicated GPS, syncing with an autopilot for hands-free trolling, or daisy-chaining multiple fish finders across a larger vessel. Installation is straightforward: connect the 4-pin plug to your Lowrance unit's NMEA port and route the cable to your secondary device. For boats with legacy or mixed-brand electronics, verify NMEA-0183 compatibility on all devices before purchase to ensure seamless data flow.
