Contemplating idea of replacing the 1040xs with the 1042 xsv. Since it comes with 2 ethernet ports I could eliminate the GCV-10 as well. The 721 it will be networked with also has 2 ethernet ports. So one port on each unit for the panoptix 21 and 30 respectively and the other port for connecting the two units together.

Anyone interested in used 1040 with GCV10 and its G30-TM transducer ? Haven't made up mind yet as extremely happy with present setup. Still having two touch units has my mind churning.
