joey2509,
What kind of fish finder do you have and what are the settings you are using? Also, what kind of fishing (anchor drift, troll etc) are you doing. And lastly where are you fishing and depth of water. All these questions will help to make sure you are adjusting the fish finder to best show fish.

PS. When you say you are seeing fish are you seeing arcs or do you have your fish finder set to show fish symbols?
