OK. looking into this still. For anyone that has it, how do you find which graphs work with this transducer. If I am going to do this I want a little bigger than a 9in screen. The way I look at it is "Cry Once", meaning I do not want to spend money on something like a graph and not be happy only to spend more money to upgrade it. I have been researching on the internet all night while I could not sleep and quite honestly I am more confused now than when I started. Doing this means that I have to get rid of my Lowrance as the trolling motor already has a transducer built in, then the Lowrance has one on the other end. I do not think that I can put all three on there. LOL They all have things I would want but I think one has to go. Anyway, any help is appreciated and I am lost. I feel like a 6th grader in a college graduate course.
