Garmin Anemometer Wind Cups f/GWS™ 10

The Garmin Anemometer Wind Cups for GWS 10 is a dedicated replacement sensor assembly designed to integrate seamlessly with Garmin's GWS 10 marine weather station. This three-cup anemometer delivers accurate wind speed measurements critical for navigation, route planning, and real-time weather monitoring aboard recreational and commercial vessels. The GWS 10 system captures true wind data essential for coastal piloting, offshore passages, and tactical weather assessment.

Weighing just 0.25 lbs with compact dimensions of 6 x 3 x 6 inches, the anemometer cups mount directly to the GWS 10 weatherhead assembly. The three-cup design provides reliable rotational response across all wind directions, translating cup rotation into precise knot or miles-per-hour readings displayed on compatible Garmin marine chartplotters and multifunction displays. This sensor design minimizes signal lag and delivers the response time boaters need when conditions change rapidly—critical during squall approach, sail trim optimization, or safety decision-making in changing weather patterns.

Replacement anemometer cups suit boaters maintaining existing GWS 10 installations who require sensor refresh due to wear, weather damage, or extended service. Weekend anglers, coastal cruisers, and offshore captains rely on accurate wind data for tactical positioning relative to current and structure. The GWS 10 anemometer integrates with Garmin's broader marine electronics ecosystem, enabling wind data overlay on navigation charts and integration with autopilot systems for automated course correction in variable conditions.

Marine weather stations like the GWS 10 remain foundational sensors for vessels operating beyond protected waters. Accurate wind speed input supports weather routing, passage planning, and real-time tactical decisions that affect fuel consumption, crew safety, and arrival timing. Garmin's modular approach to weather station assembly allows targeted replacement of wear items without full system replacement, preserving the integrity of existing installations.
