Jeff,

My hope is that Raymarine service centers pick up the TacTick service. For now the best interface between Raymaine and TackTick is the T122 NMEA interface if you have the Raymarine ST60+ multifunction display which has NMEA 0183 available. If you don't have the ST60+, I would NOT buy the Raymarine Seatalk to NMEA interface but would buy the Brookhouse NMEA multiplexer with Seatalk interface. This provides much more flexibility as you update your instruments in the future. No matter what, you will need the TackTick T122 interface for NMEA 0183 connections.
