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.
While you can find fish with one of those original units, today’s sonar systems—coupled with GPS navigation—offer imagery, functions, and overall performance unparalleled in fishing history. 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. To spice things up, we included a few chartplotting options, along with a fine camera combo. Fish finders, sonar, are a must have for ever angler.
- One of our favorite features on this new dual-frequency sonar unit is the Accu-Fish function, which not only recognizes whether it’s pinging individual or multiple fish, but also computes echo strength to estimate fish size from 10 to 199 cm at depths of 2 to 100 meters. Also cool, the FCV-587’s Bottom Discrimination feature tells you if the major bottom composition is rocks, gravel, sand, or mud. We also like the White Line technology, which distinguishes fish from bottom by changing the strongest signal color to white. It also helps judge fish school density. Other nice touches include a bright, 8.4-inch color LCD that you can see even at odd angles while wearing polarized glasses. $1,695. furuno.com
