Why Choose the Garmin ECHOMAP Ultra 2 166sv?
A chartplotter with built-in sonar replaces separate navigation and fish-finding units, so you work from one screen with one mount and one power feed. The Garmin ECHOMAP Ultra 2 166sv is built for anglers and cruisers who want clear charts and a clear picture of what is below the boat.
Use the specifications above as your starting point, then match screen size, sonar type and chart coverage to the way you fish or cruise. For more help deciding, read our chartplotter comparison, best fish finders by budget, guide to reading a fish finder screen.
