Using SI fish will usually show as white. with DI or 2D what are they supposed to look like. I know you have to get to know how to read your display. But I think some basics would help to start a lot of people off.

On DI fish should show up a s white dot. On 2d sonar it depends on what you have your unit set to. I always use arches instead of the fish symbols, Its more accurate. I cant stress enough how important it is to thoroughly understand how sonar works. I get emails all the time asking these very questions. I found a website that really explains how sonar works and what your looking at. http://biggeorgiaspots.com/boats-and-electronics/traditional-2d-sonar.html (http://biggeorgiaspots.com/boats-and-electronics/traditional-2d-sonar.html) Id go into detail about this but its very hard to explain in text only. Without pictures, its very hard. Heres a pic of a really nice 2d image. this is a small school of walleye feeding on a school of perch. Walleye are near the bottom and you can see the arches very well. Good Luck
