All I can say is I hope it works all hardware, equipment, and graph will be here tomorrow. From what I have read the HDS,FS, and Ti models all have the Ethernet port but it’s best not to connect them threw Ethernet due to software differences but you can connect threw NMEA. The difference with Ti2 is that the unit has no Ethernet port and cannot be synced with other units so fingers crossed NMEA will atleast let me share waypoints. With the ducers I don’t think I will have issues because I’ll be running the same 3 way active image transducers front and back. With you saying you do this with the FS/Ti gives me that much more hope lol.
