With its bright, crisp 5-inch high-resolution VGA color display, the echo 551dv has Smooth Scaling™ which provides smooth transitions from shallow to deep water and back again. Narrow-to-wide viewing cone angles give you a big picture well beyond the sides of your boat — from shallow water down to 2,300 feet maximum¹. Also includes sonar history rewind and 4,000 W peak-to-peak power. Quick-release tilt/swivel mount plus transom and low-profile trolling motor transducer mounts make installation a snap
