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.
