A Powerfully Simple Hi-Res 5-inch Color Fishfinder
- Exclusive advanced HD-ID™ sonar with or without a transducer (depending on version)
- High-resolution 5-inch diagonal VGA color display
- Transmit power (RMS)/(Peak-To-Peak): 500 W/4,000 W
- Frequency: 77/200 kHz included (supports 50/200 kHz)
- Quick-release tilt/swivel mount and transom/trolling motor transducer and mounts included
The color echo 551c is a premier fishfinder with one of the brightest 5-inch high-resolution VGA color displays on the water. Its built-in advanced HD-ID sonar with or without a 77/200 kHz transducer (supports 50/200 kHz transducer, sold separately) offers extra sharp resolution and detail on fish, structure and bottom returns with the power to scan to a 2,300-foot maximum¹ depth.
With its simple, streamlined interface with 4,000 W peak-to-peak power, the echo 551c has wide viewing cone angles (60/120 degrees) optimized for targeting fish beyond the sides of your boat in deep or shallow water – in addition to Smooth Scaling™ depth-range adjustments and sonar history rewind.
