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.
