Davis 4-Conductor Extension Cable - 40'

The Davis 4-Conductor Extension Cable – 40' is purpose-built for anglers and boaters who demand reliable weather station connectivity across larger vessels and waterfront installations. Whether you're monitoring conditions from the helm or tracking atmospheric data at a remote dock, this marine-grade extension cable bridges the gap between your Davis Instruments weather instruments and display consoles. At 40 feet, it delivers the reach necessary for today's modern sport fishing boats, cruisers, and commercial fishing operations where instrument placement demands extended runs without signal degradation.

This standard 4-conductor cable is engineered for the marine environment, with waterproof coupler kits included to safely join two cables together when extended distances require it. The four-conductor design supports full data transmission between Vantage Pro2, original Vantage Pro weather stations, and WeatherLink compatible display systems, Wizard, or Monitor consoles. Built to withstand saltwater exposure, UV radiation, and deck-level wear, the cable's marine-rated construction ensures years of trouble-free operation in demanding boating conditions. The compact 0.6 lb weight and flexible design make installation straightforward, whether routing through cabin runs, along rails, or across the flying bridge.

Serious boaters who rely on real-time wind, temperature, and pressure data for navigation and performance optimization will appreciate this cable's compatibility with Davis's full ecosystem of marine instruments. The 40-foot length eliminates the need for expensive custom installation work and provides flexibility in sensor placement—critical for vessels where optimal wind-reading exposure may require mast-height or elevated placement far from helm displays. Installation is straightforward: connect directly to compatible Davis weather stations and consoles using the weatherproof couplers, and couple additional cables if your vessel's layout demands even greater reach. For commercial fishing operations and serious cruisers, this extension cable represents essential infrastructure for dependable onboard weather intelligence.
