Take fishing to the next level.

SONAR SUPPORT

This chartplotter supports a variety of Garmin transducers (sold separately), including the Panoptix LiveScope™ scanning sonar system, which lets you see all around your boat in real time.

VIVID COLOR PALETTES

High-contrast vivid scanning sonar color palettes make it easier than ever to distinguish targets and structure.

OPTIONAL TRANSDUCER BUNDLE

Select the transducer bundle to add a GT56 transducer for Garmin CHIRP traditional sonar and Ultra High-Definition ClearVü and SideVü scanning sonars. With three scanning sonar frequencies and 20% greater range for our UHD SideVü sonar, you’ll get top performance at all depths.

PRELOADED MAPPING

Experience unparalleled coverage and detail with preloaded LakeVü g3 inland maps featuring integrated Navionics^® data. Maps cover more than 18,000 lakes with up to 1’ contours.

QUICKDRAW CONTOURS

NETWORK CAPABLE

If you have multiple compatible ECHOMAP UHD or ECHOMAP Ultra devices on your boat, the 7” and 9” models can share information — such as sonar, user data and charts — with them.

Connect to your compatible autopilots, digital switching, weather, Fusion-Link^™ audio system, media, VHF, AIS, engine data, heading sensors — such as the SteadyCast^™ sensor — and more from one screen.

Built-in Wi-Fi^® connectivity pairs with the free all-in-one mobile app for access to the OneChart™ feature, smart notifications, software updates, Garmin Quickdraw™ Community data and more¹.

FORCE™ TROLLING MOTOR COMPATIBILITY

Take control of the most powerful and efficient trolling motor available², route it to waypoints, follow tracks and more from the screen of your chartplotter.

ENGINE CONNECTIVITY

Connect this chartplotter to different kinds of engines — including select Mercury and Yamaha® models — to see RPMs, fuel flow, temperature, trim and other important information at a glance. You may need additional hardware, so be sure to check with your engine manufacturer.
