Fish finders Sonar (fish finders) has been a mainstay of serious anglers' strategies ever since Lowrance launched the Little Green Box back in 1959. Now, thanks to a steady stream of technological advancements, fish finders offer a wider window than ever into the mysteries of the underwater world.

Our list (presented in alphabetical order) includes a variety of choices in sonar at different price points, so you can match our picks to your style of fishing, without breaking your budget.
