Garmin International Echomap Plus

The Echomap Plus 94sv includes the GT51 transducer right out of the box, so you have everything you need to start using sonar features immediately.

The keyed-assist interface is designed specifically for marine environments. While the 9-inch screen is a responsive touchscreen, the physical keys allow you to navigate menus and make adjustments even when your hands are wet or the boat is rocking in rough water.

While it comes preloaded with BlueChart g3 coastal U.S. maps, you can certainly use it on inland lakes. You may want to purchase additional LakeVü map cards if you need detailed inland contour data, but the sonar and GPS functionality work perfectly in any body of water.

Quickdraw Contours allows you to create your own high-definition fishing maps with 1-foot contours in real-time as you drive the boat. It is incredibly useful for mapping uncharted areas or finding hidden structure that standard charts might miss.

Yes, the Echomap Plus 94sv supports Garmin's Panoptix all-seeing sonar. This allows you to see real-time, live images of fish and structure around your boat, though you will need to purchase the Panoptix transducer separately.

Connecting to the ActiveCaptain app lets you wirelessly update your device's software, download new maps, and sync user data like waypoints and routes. It essentially turns your smartphone into a remote control and data management hub for your fishfinder.
