Sorry no pix of shield as it was on somebody elses boat where I saw it. But just imagine if one took a 4by 6 inch pc of metal put a 80 or 90 degree bend in it across the 4 inch length like a angle iron one side is now 2 x 4 inches with 2 holes to screw to boat a inch or so above transducer the 4 x 4 section sticks out over ducer blocking rooster pee.............I aam sure U can make a fancey one with a little thought
