I've had the TackTick wind, speed, depth and temp system installed on my boat since 2007. I've been very happy with it. My installation is a bit unusual, since the instrument displays are mounted on a Beckson 5"x12" opening port, which allows them to be swung up out of the way when at anchor and provide the cabin with more ventilation. The port also protects the instruments from getting hit and prevents the covers from being pulled off accidentally.
