DualBeam PLUS™ Sonar
Your Fishfinder 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.
