DualBeam PLUS™ Sonar
Your 700 Series™ 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. The 20° center beam is focused on
the bottom, to show you structure, weeds and cover. The 60°
wide beam is hunting for fish in the wide coverage area.
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™ Sonar
(with optional-purchase QuadraBeam
TM
transducer)
Your 700 Series™ Fishing System also supports
QuadraBeam™ sonar with the purchase of
an additional QuadraBeam™ transducer.
QuadraBeam™ sonar provides an extremely
wide 90° area of coverage. QuadraBeam™ starts
with two 45° 455 kHz beams for a continuous
90° of uninterrupted side to side coverage to 160
feet. These Side Structure locating beams reveal
fish and structure to the left and right of your
boat near the bottom. For structure directly
below your boat, Quadrabeam™ uses DualBeam
PLUS™ technology.
WideSide® Sonar
(with optional-purchase WideSide® transducer)
Your 700 Series™ Fishing System also supports
WideSide® sonar with the purchase of an additional
WideSide® transducer. The WideSide® transducer is a
specialized "side-looking" transducer that is extremely
useful for bank fishing or looking for bait fish in open
water. The WideSide® transducer uses three different
sonar elements that transmit signals to the left, right
and straight down from your boat. The downward
beam is 200 kHz with a 24° area of coverage. This beam
maintains a continuous digital depth readout from the
bottom directly beneath your boat. The side beams are
455 kHz with a 16° area of coverage. The side-looking
elements can be used independently, or together to
locate targets near the surface of the water on either
side of your boat.
