So I have a technical question about side scanning sonar/fish finders, I troll for trout and koks that early in the year are close to the surface and move deeper later in the year. As you troll along, the fish move around away from the boat. How does the beam on the new fish finders work? Does it go 180 Deg with the boat (like Humminbirds video) or do they have angle towards the bottom. Logic tells me they are angled towards the bottom but that is why I am asking.
