All best just shipping with UPS is unacceptable .. this service provider is focused on large business customers and offers pathetic service to private customers.
Installed on a 26 foot mast top. To calibrate the wind indicator, you have to press the set button on the NMEA module, this has to be taken into account on the Monday and cannot be put behind the fairing (you have to come to it once the system is running and the wind is coming from the front). With fast circulating winds, for example at anchor, you notice that the display is sluggish (compared to a wired system) and that the data is not sent continuously but about every second. This shouldn't be a problem when sailing. From my point of view, the advantage of wireless mounting outweighs the problem.
