The power output is the amount of energy
generated by the sonar transmitter. It is
commonly measured using two methods:
• Root Mean Square (RMS) measures
power output over the entire transmit
cycle.
• Peak to Peak measures power output
at the highest points.
The benefits of increased power output are the ability to detect smaller targets at
greater distances, ability to overcome noise, better high speed performance and
enhanced depth capability.
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. 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.
