I bought a 2008 Nitro Z-7 (first bass boat) that came with a brand new Xi5 trolling motor. The boat came with a 7Ti and a Hook 2. I am going to upgrade to 10" or 12" units. My question is am I locked in with Lowrance or will this work with Hummingbird? Am I better off staying with Lowrance for connectivity of the units? I also wonder if I should wait until the new products roll out before I make the purchase for year old technology now?
