Catfan,ill try to help you on this the best i can but most shots that i show i would rather not advertise the corrordances. .this picture is coming out of ky. Dam marainia. That's the rifts raft break wall to the right. Nothing special here had my non hd 998 running while leaving the marainia.setting properly close to default.when i get home ill post a link to a video that i made using my 597 on the coffers dam in front of ky.. Dam it doesn't show the corrordances either but if you watch the video at the end it shows the dam and were my boats at.its something that all users both Lawrence and humminbird would enjoy . of coarse the humminbird users will find it easier than the Lawrence usersjust kidding around.........i forgot my tube password its at home
