Hi - new to the boards. We have a NavNet TZT2 but currently no AIS. We are wanting to install an AIS and have had a hard time finding a Furuno Class B transceiver that is in stock. Currently waiting to see the FA-70 hit the shelves, but it looks like dates keep pushing out. Anyone have any insight? We'd prefer to have a Furuno brand AIS to reduce compatibility issues, but would welcome recommendations from others who have used non-Furuno AIS transceivers. Thanks much!
