Just looking for opinions on how well they work or don't. Or if there's a better option out there etc.. Read a few reviews online that were mixed. Similar to you I don't currently have a NMEA 2000 setup on my boat and need to purchase that as well. I'm really hoping this will help get back on top of humps and pinnicles quickly when doing short drifts. It drives me nuts trying to circle back only to have the boat pointing in the wrong direction on the screen when you think you lined up.
