Garmin Mast Cable - 25M (82')

The Garmin Mast Cable – 25M (82') is a marine-grade signal extension cable engineered to connect wind transducers to compatible Garmin instrumentation systems on sailboats and racing vessels. Constructed to marine specifications, this 25-meter cable delivers reliable signal transmission from gWind and gWind Race wind transducers mounted at the mast top down to below-deck display units, enabling accurate wind speed and direction data across your navigation network.

The 25-meter length accommodates vessels with tall masts or distributed console configurations, eliminating the need for intermediate connectors that can introduce signal loss. Garmin's marine-cable design resists salt-air corrosion and maintains electrical integrity in high-humidity offshore environments. The cable terminates with industry-standard marine connectors compatible with Garmin's GMI, GNX, and GND black box systems, as well as dedicated wind-data protocols used in modern sailing instrumentation. Installation runs cleanly through existing cable channels and conduits without requiring additional hardware modifications.

This cable is essential for sailors upgrading to networked wind data, racing teams integrating performance metrics into tactical displays, and cruising vessels requiring long-cable runs from masthead sensors to pilot houses or navigation stations. Garmin mast cables are direct replacements, supporting both standard gWind transducers and the specialized gWind Race variant used in competitive offshore racing where precision wind data directly influences sail trim and course strategy.

Compatible with GMI Wired Start Pack 52, GMI/GNX Wired Sail Pack 52, GND 10 Black Box Bridge, GNX Wired Sail Pack 43, GNX Wired Sail Pack 52, and Garmin gWind systems, this cable simplifies integration into existing Garmin marine networks without additional adapters or software configuration.
