Humminbird AS EC 30E Ethernet Cable - 30'

The Humminbird AS EC 30E Ethernet Cable – 30' is a marine-grade connectivity solution designed to link two Ethernet-capable Humminbird units across extended distances on your vessel. Whether you're running dual sonar systems, integrating a chartplotter with a bow-mounted transducer array, or connecting networked fish finders across your boat, this 30-foot cable eliminates the distance limitations that short factory cables impose. Anglers and serious boaters depend on reliable Ethernet connections to maintain real-time data flow between electronics, especially when deploying forward-facing and structure-scanning sonar simultaneously.

Built to withstand the marine environment, the AS EC 30E cable meets Humminbird's OEM specifications for signal integrity and shielding, ensuring data packets transfer without loss of clarity or refresh rate on your sonar display. The 30-foot length accommodates larger center consoles, cabin cruisers, and multi-station setups where conventional 6–15 foot cables fall short. Constructed with weather-resistant jacket materials and proper shielding to resist electromagnetic interference from onboard radio systems and engine noise, this cable maintains consistent performance in saltwater and freshwater conditions. The standardized Ethernet connectors are compatible with all Humminbird units equipped with Ethernet ports, including HELIX, ONIX, and select legacy models.

Professional anglers running multiple sonar heads, tournament competitors requiring redundant electronics, and boat owners retrofitting existing systems with new Humminbird units benefit most from this extended-reach cable. Installation is straightforward—simply plug one end into your primary unit and the other into your secondary display or transducer module, then secure the cable along your gunwale or through-cabin routing to prevent water pooling or chafing. This product is ideal for boats exceeding 25 feet where electronics separation demands reliable, interference-free data transmission.
