QuadraBeam PLUS™ Sonar
(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.
