Nice looking set up, are they all networked and running off a single transducer?
These are Humminbird Helix's and all networked together with the HB ethernet box mounted under the console.
Of the 2 units on the console, one unit is an SI and the other is the "plain" version without SI or DI. The bow unit has DI. I think I got all that right. So I have a SI transducer on the transom which runs to the SI unit on the console. I also have a through-the-hull transducer glassed in which runs to the "plain" unit on the console which I use only for GPS and my Lakemaster mapping and allows me to have depth readings on plane.
I also have the Ulterra trolling motor (which I love) with a built in sonar transducer but I still haven't decided how much I like it. One problem is that I have the 60-inch shaft which means my bow graph will tell me my depth is only 2 feet when it's actually 4-5 feet. This is because the transducer is 60 inches down below the deck and closer to the bottom of the lake than my SI transducer under the jackplate which sits inches from water level. I can raise the Ulterra up slowly and watch my depth go 2...3...4...
On the other hand, it's sometimes nice to know if my trolling motor is about to start grinding on the bottom.
I was worried that two 12-inch graphs on the console would stick out into the middle of the boat. And with a dual console, I could easily get my beer gut hung up on the graphs while trying to squeeze through and get up to the front deck. But it turned out great and this is a photo from the bow showing that the two 12-inch screens don't stick out any further than the console mount:
