Davis 4-Conductor Extension Cable - 8'

The Davis 4-Conductor Extension Cable – 8' is an essential accessory for mariners and weather-conscious boaters who demand reliable data transmission from their deck-mounted instruments to below-decks displays or control units. Built to Davis Instruments' proven marine standards, this eight-foot extension cable seamlessly extends the reach of Vantage Pro2 and original Vantage Pro weather stations, as well as compatible WeatherLink systems, allowing flexible placement of sensors and consoles across varied vessel layouts. Anyone running a serious weather monitoring or data logging system aboard recognizes that cable length constraints can force compromises in sensor placement—this solution eliminates that friction.

The four-conductor design carries both power and signal over a single, compact run, minimizing clutter in tight marine environments where space is at a premium. Each cable is engineered with marine-grade construction to withstand salt spray, UV exposure, and the constant vibration inherent to life on the water—critical factors that separate purpose-built marine gear from landlocked alternatives. The Davis 4-Conductor Extension Cable includes waterproof coupler kits, enabling two cables to be joined together when an eight-foot span proves insufficient, allowing customization for larger vessels or complex installations without requiring expensive splitter boxes or additional power supplies.

This extension cable is ideal for cruising sailors, fishing boat operators, and weather enthusiasts who need to locate anemometers, rain gauges, and temperature sensors at the masthead or boom while keeping displays and control interfaces in the cabin or wheelhouse. Compatibility extends across the entire Vantage Pro2 family and original Vantage Pro stations, making it a safe choice whether your vessel runs a wireless weather station or a fully cabled system. At just 0.2 lbs and compact dimensions, installation requires minimal planning; the included waterproof couplers ensure sealed connections that won't corrode or fail under continuous marine service.
