Thinking about adding two 9" Elite Ti2 with 3 in1 transducers to my boat, one at the bow and one at the console. I'm also considering the live sight for the front graph as well. Is it as simple and wiring them to the battery, plugging in the tranducers and live sight then letting the two graphs connect wirelessly?? Seems too easy, but a friend of mine swears it's simple plug-n-play....I'm betting he is wrong...
