Since my mast is down, I am toying with the idea of installing a wind speed/direction unit. I seen the Raymarine T101 (Tacktick) on sale and got me curious. The search here brought up some older hits but was wondering if anyone has any comments on their unit. It seems to have had problems with the wireless signal and the bearings in the sending unit going bad. It looks like the sending unit and the gauge panel is powered by a solar charged lithium battery. Just looking for some pros/cons.
