I am going to purchase two new FF next month. I am already set on the 898c for the console but wanted some opinions on the Bow FF. I am thinking of either a 597ci or a 788ci with transducer mounted on trolling motor. I want it to be compatible to interlink to the 898. What are your opinions?? I also have a couple questions: Does the 597ci have card slots the specs I saw didn't mention them and can the 597 be interlinked to the 898? All opinions about the 597/788 would be appreciated.. THANKS
