Ethernet Cable for Humminbird 720073-4 AS EC 30E

This 30ft Ethernet cable is a replacement for Humminbird part 720073-4 (AS EC 30E), designed to link compatible fish finders, sonar units, and displays across your boat's network.

Overview

This Ethernet cable serves as a direct replacement for the Humminbird 720073-4 / AS EC 30E cord, letting you network sonar and chartplotter units across your vessel. At 30 feet, it gives you the reach to connect helm and bow stations without straining or splicing. It is built for anglers and boaters running multi-unit Humminbird setups who need a reliable data link on the water.

Built For Performance

• 30ft length supports long runs between helm and bow or stern stations
• Direct cross-reference to Humminbird 720073-4 and AS EC 30E
• Shielded Ethernet construction for stable sonar and waypoint data transfer
• Molded connectors resist corrosion in marine environments
• Flexible jacket routes cleanly through rigging tubes and gunwales

Fits These Machines

• for Humminbird units compatible with the AS EC 30E Ethernet network
• for Humminbird sonar and fish finder models accepting 720073-4 cabling

On-The-Job Use

• Networking helm and bow fish finders on the same boat
• Sharing sonar, GPS, and waypoint data between stations
• Replacing a damaged or short original Ethernet cord
• Rigging new electronics on freshwater and saltwater boats

Specs At A Glance

Good To Know

Q: Is this an original Humminbird cable? A: No, it is a replacement Ethernet cord made for Humminbird systems that use the 720073-4 or AS EC 30E connection. Confirm your unit accepts this cable type before ordering.

Q: Will 30 feet reach between my stations? A: Measure your planned cable route along the actual rigging path, since runs often need more length than a straight-line estimate suggests. This cord suits most helm-to-bow layouts on mid-size boats.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
