QuadraBeam PLUS™ Sonar

(with optional-purchase QuadraBeam PLUS™

transducer)

QuadraBeam PLUS™ sonar provides an extremely 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.

NOTE: Contact our Customer Resource Center to determine which accessory transducers are compatible with your Humminbird® Fishing System, or visit our Web site at humminbird.com.
