PRE OWNED STOWE WM 1644 STOWE WM 1644 ANEMOMETER DISPLAY

PRODUCT OVERVIEW

The Stowe WM 1644 is a high-reliability wind instrument designed for both performance sailing and motor yachting. It features the classic Stowe "Circular" display format, combining a physical analog needle for 360° apparent wind direction with a built-in digital LCD for wind speed. Known for its extremely low power consumption and robust waterproof seal, the WM 1644 is a staple for vessels running legacy Stowe Navigator or Dataline networks. It remains highly compatible with older masthead units using pulse-speed and phase-angle signals.

KEY FEATURES & APPLICATIONS

Instant Direction Awareness: The mechanical needle provides a lag-free visual of wind shifts, which is essential for helmsmen trying to maintain a steady upwind course.

Low Current Draw: Optimized for offshore sailing where power conservation is critical; the unit draws minimal amperage even with backlighting active.

Tactile Calibration: Includes rear or front-access trim adjustments for aligning the masthead unit to the boat's centerline without needing a computer.

Dataline Compatibility: Can be integrated into larger Dataline X or Navigator systems to share data across multiple repeaters.

Rugged Marine Housing: Built with UV-stabilized materials to prevent the "yellowing" or "fogging" commonly seen in cheaper vintage instruments.

TYPICAL CONDITION (USED/REFURBISHED)

Needle Performance: Refurbished units are tested to ensure the needle doesn't "jitter" and moves smoothly across the full 360° range.

LCD Clarity: The digital speed display is inspected for "sun-burn" or fading, which is common in units that have spent years in tropical environments.

Seal Integrity: Used units often receive new gaskets to ensure they remain waterproof when flush-mounted in an exposed cockpit.
