I would stay as far away from Raymarine if I possibly could. I've had to replace the masthead sender recently after just 5 years and the boat speed is not even slightly accurate so the true wind is never correct. Unfortunately, Raymarine has horrible customer service and their support techs are of little use in most cases. They couldn't or wouldn't tell me the horsepower of the motors they use in their rotary drive units! Even their big commercial network systems are unreliable and their support on them is no better.
I've personally had great service from Garmin electronics, though admittedly have never used their wind instruments. Their customer service and tech support are great, as well.
