Need help. I'm ready to get the garmin panoptix ice bundle and mount it on my boat during the summer. but I'm not sure if it will do what I'm expecting. i fish lots of docks in okaboji and steep banks with fallin trees. I'm wondering if I'll be able to see the difference between fish and structures and how well it will work fishing this way. if you have one please tell me what you think of it. worth the money ?
