Quadrabeam Plus™ Sonar (575 Fishfinders Only) - Humminbird 500 series Operation Manual

For structure directly below your boat, Quadrabeam PLUS™ uses a DualBeam
PLUS™ 200/83 kHz 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.
