Dual gauges

[schrater]

I'm looking to install a new combo depth-speed transducer, but I'd like to be able to duplicate it to two separate gauges, one in the main cockpit and one up on the fly bridge. I'd prefer to not have two thru-hulls. And I don't want to splurge as far as full primary/slave MFDs. Anyone know of such a configuration? I feel like this is a common arrangement on sailboats.

I know many of the Lowrance fish finders will share speed and depth (numbers only) over NMEA. There are a few that can share all bottom data but that amount of data normally requires Ethernet which only comes on some units.
