Bettw..... you've got my curiosity up on this comparisons thing that you've been doing.you haven't posted any side by side pictures that we all wanted to see and the hds that your selling on ebay well those pictures imo seem to be lacking.maybe your setup. Im not sure but i think it would be helpful to all seeing that you opened your own can an all for you to show side by side comparisons with shots of the transducer location of each.i hope that you can do this because i think this would be helpful.thanks
