DualBeam PLUS™ Sonar

(858c, 898c SI, 958c, 998c SI)

The Fishing System uses a 200/83 kHz DualBeam PLUS™ sonar system with a wide (60°) area of coverage. DualBeam PLUS™ sonar has a narrowly focused 20° center beam, surrounded by a second beam of 60°, expanding your coverage to an area equal to your depth. In 20 feet of water, the wider beam covers an area 20 feet wide.

DualBeam PLUS™ sonar returns can be blended together, viewed separately, or compared side-by-side. DualBeam PLUS™ is ideal for a wide range of conditions - from shallow to very deep water in both fresh and salt water. Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions, and transducer installation.

QuadraBeam PLUS™ Sonar

(optional-purchase QuadraBeam PLUS™

transducer only)

Your Fishing System supports the optional-purchase QuadraBeam PLUS™ transducer. QuadraBeam PLUS™ sonar provides a wide (90°) area of coverage. QuadraBeam PLUS™ starts with two fan-shaped 35° 455 kHz Side Structure locating sonar beams to spot fish, bait, and structure to the left and right of the boat over an area of the bottom that’s always equal to twice your depth.

For a detailed view below the boat, QuadraBeam PLUS™ uses DualBeam PLUS™ technology, with precision 20° and wide 60° beams. QuadraBeam PLUS™ finds more fish faster, and can even tell you where to put your bait by showing if fish are to the left, right, or directly beneath your boat.
