Eco Sounder
The Garmin echo™ 551dv Eco Sounder is a high-performance fishfinding tool designed to deliver superior clarity and accuracy beneath your boat. Its bright, crisp 5-inch high-resolution VGA color display ensures that every detail under the surface is visible, whether you’re in shallow streams or deep lakes.
Equipped with Garmin’s exclusive Smooth Scaling™ technology, it provides uninterrupted sonar imaging as you transition between different depths — giving you real-time updates without screen lag. With its advanced sonar featuring both narrow and wide cone angles, you gain an extended underwater perspective well beyond the sides of your boat.
