All-in-One Marine Monitoring
The Garmin GMI 40 Wireless Sail Pack is a complete sailing instrument package designed to deliver essential wind, speed, depth and temperature data at the helm. Featuring two GMI 40 marine instruments, a gWind Wireless 2 wind sensor and GDT 43/GST 43 transducers, this integrated system helps sailors monitor vessel performance, assess changing conditions and navigate with confidence.
The dual 4.3-inch touchscreen GMI 40 displays provide clear, customizable views of critical sailing information, allowing you to configure each instrument to display the data most important to your journey. The gWind Wireless 2 sensor measures wind speed and angle while transmitting data wirelessly to the instruments, eliminating the need for a cable through the mast and simplifying installation. Its advanced sensor design helps deliver accurate wind measurements, even in lighter wind conditions.
The included GDT 43 and GST 43 transducers provide essential water-depth, speed-through-water and temperature readings to help monitor underwater conditions and vessel performance. With NMEA 2000® connectivity, the GMI 40 instruments can integrate with compatible Garmin marine electronics and onboard sensors, creating a connected navigation system that brings important vessel data together at the helm.
Combining wireless wind sensing, customizable touchscreen displays and comprehensive sailing data, the Garmin GMI 40 Wireless Sail Pack offers a convenient, integrated solution for sailors seeking greater awareness of their vessel and surrounding conditions while underway.
