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.
DualBeamPLUS™ is idealfor awide rangeof
conditions - from shallow to very deep
water in both fresh and salt water. Depth
capability is affected bysuch factors as boat

conditions and transducer installation.
