Another question about fish finders

[wiperhunter2]

Thanks for the help BLM, I know I can always get great info from you. All I was saying was, I did address the pixel issue at the beginning and I thought I had that part figured out. The issue about frequency and the degree of the cone was what I wasn't so sure about, along with you and the other guys I think I understand what I need now, thanks everyone for your comments. WH2
