Why talk to a local when you can fish like one?

They say locals know best. But anyone who says that hasn’t fished with the ECHOMAP UHD2 5″ and 7″ Chartplotters with clear, crisp sonar and mapping.


  • The bright 7″ keyed display is made for convenience.
  • Get double the views¹ with Garmin CHIRP traditional and ClearVü scanning sonars.
  • What’s under the water looks even better with high-contrast vivid colour palettes.
  • Wi-Fi® connectivity² between compatible chart plotters makes it easy to share info.
  • Enjoy No. 1 in mapping with our BlueChart® maps with Navionics® data.
    With crisp, clear traditional sonar and brilliant ClearVü sonar, the fish will have nowhere to hide.
    High-contrast vivid scanning sonar colour palettes make it easier than ever to distinguish targets and structures.
    Your ECHOMAP UHD2 device supports a variety of Garmin transducers for two types of sonar: Garmin traditional and ClearVü scanning sonars.
    Know the waters you’re in as if you grew up fishing them by using built-in BlueChart g3.
    If you have another compatible ECHOMAP UHD2 Chartplotter on your boat, the 5″ and 7″ models can wirelessly share information such as sonar, waypoints and routes with them.
    Built-in Wi-Fi connectivity pairs with the free all-in-one mobile app for access to the OneChart™ feature, software updates, Garmin Quickdraw™ Community data and more²
