I am not sure about a through the hull transducer. I only had them carpet the cockpit area. I had already done the front and back decks. They are supplying the carpet and doing the removal and installing the new carpet for 800. I just simply don't have the time to tackle doing the cockpit area. They finished the wet sanding and buffing today and they are going to send me pics of it tomorrow. I can't wait to go and get it.
