Dualbeam Plus™ Sonar - Humminbird 343c Operation Manual

DualBeam PLUS™ Sonar
Your 300 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.
