DualBeam PLUS™ Sonar
Your 700 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. 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.
