QuadraBeam PLUS™ Sonar
(with optional-purchase QuadraBeam PLUS™
transducer)
Your 700 Series™ Fishing System also
supports QuadraBeam PLUS™ sonar with
the purchase of an additional 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.
