AdvanSea WIND S400 – High-precision marine wind indicator for confident navigation

The AdvanSea WIND S400 is a versatile wind instrument designed for sailors who demand clarity, speed and reliability at the helm. It delivers instant wind direction in both analog-style and digital views, calculates true and apparent wind when networked with your boat data, and offers outstanding readability on a dual-line backlit LCD. With robust marine construction and NMEA 0183 connectivity for easy integration, the WIND S400 turns changing conditions into clear decisions. Choose it as a display-only unit or as a complete kit with masthead sensor and 25 m cable, and enjoy expert service when you order at Stratosens.com.

Key Benefits and Applications

• See wind at a glance – Large, high-contrast digits and an analog-style arc let you read wind shifts instantly, ideal for quick tacks, gybes and course corrections under sail.
• Sail faster and safer – True and apparent wind data support better trim and routing, helping optimise speed while keeping clear safety margins in rising gusts.
• Seamless integration onboard – NMEA 0183 input and output allow the WIND S400 to share data with compatible instruments, chartplotters and autopilots for a unified navigation setup.
• Confidence in rough weather – A rugged, marine-rated front face and anti-fog display maintain visibility and operation when spray, rain or temperature swings would defeat ordinary gauges.
• Smart alerts that matter – High-wind and low-battery alarms draw attention to critical events, while trend indication highlights changes so you can react before they escalate.
• Flexible for any install – Available as display-only or as a complete package with masthead sensor and 25 m cable, making it perfect for new builds, refits or instrument upgrades.
• Backed by specialists – Purchase with confidence from Stratosens.com, where product expertise and responsive support streamline selection, installation and setup.
