Dualbeam Plus™ Sonar - Humminbird 700 series Operation Manual

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. 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.
