Dark area on side scan?

The dark stripe in the 800kHz SI images could also be the "null sector" in the 800kHz beam form ...

(notice the 455kHz in the beam form diagram above doesn't create a "null sector")...

I would like to see humminbird add the 800kHz chirp to the 360.I believe that I could use the null area to my advantage. http://i826.photobucket.com/albums/z...ps16mexdtt.jpg
