Features

The Model 220WXH is Airmar’s solution for commercial fishing weather monitoring applications. Thermostatically controlled heating system for operation in ice-prone areas. Feature rich, in a durable, rugged, small footprint that is IPX4 or IPX6 rated; the model 220WXH calculates the theoretical wind speed and direction based upon the apparent wind, speed of the vessel, and vessel heading.

The Model 220WXH internal 10Hz GPS and three-axis electronic compass provide heading, position, speed over ground and course over ground functionality that is required for theoretical wind data processing and mobile applications. Equipped with a 3D compass with dynamic stabilization provided by the 3-axis rate gyro also enhances the rate of turn data.
