I just got a new hb899 i got it all hooked up yesterday and went to the lake for a couple hours to check it out. I only had a short time but i circled some spots where i knew there was some brush but never saw anything on side imaging. I went through the si enhance settings pretty thoroughly still nothing. Are there people that knowledgeable about these things that would go on the water with you to show what they can do. Im in central illinois.
