At full disclosure, I'm new to the boat electronics game. I spoke with a guy at Bass Pro Shop about a couple options, and he said that the 7Ti was just a "repackaged" Gen II version of the HDS model. I'm reading some negative feedback on the 7Ti and wanted to know if anyone had any good input. I was thinking about investing in a Elite 7ti and pairing it to a Motorguide Xi5 Sonar/GPS. Is it worth going with the HDS7 for double the $?
