ok guys, not to beat a horse that has been beaten over and over again....but I may end up convincing the boss that I need a new sonar unit....what are your experiences with the lowrance hds 7 and ss or the humminbird 898 si.....just curious if I do get to pull the trigger......I am leaning towards the lowrance so I can move my 337c to the front and network them together.....thoughts?
