Picked unit up Friday. de-installed GSD24, 4210 and M260 transducer. Unit fits perfectly. Everything hooked up and working. Software updated with Active Captain.
Now I have:
8612xsv at helm connected to B744 transducer
943xsv in overhead box connected to GT51M-TH transducer, external SD card reader
GPS24xd GPS 1-meter accuracy, magnetic heading sensor, NMEA2000
GMR18 radar - 1st generation planning on upgrade next year
iCom M506 DSC/NMEA200
g3 Vision VUS010R for shaded relief mapping
I do like that I can connect to the boat (sitting outside my kitchen) from my I pad on the kitchen island. I can access both chart plotters as if I'm on the boat. Switching between the boat network and home network is a pain and sometimes doesn't connect on first try but eventually works. Single SD card in external reader for Active Captain card - works well for screen capture and getting the card out.
The xsv sounders on the network are neat. You can configure different displays to use transducer of your choice (CHIRP or 50/200) for traditional, split frequency and split zoom. Also has traditional CHIRP, SideVu and ClearVu.
Unit in place waiting on screws, trim and caulk.
