Is there a way to run a second screen off my DF? Id like one at the helm and one at the stern, so when Im running my downriggers, I dont have to keep yelling up front for depth changes? Just a screen I dont need to do any changes to the DF from back there, I just need the screen picture and depth. Someone told me that NEMA 2000 is the way to go, but I have yet to find the," Idiots Guide to NEMA 2000". Any help is appreciated!
