Whopping 16” High Resolution Display!

The Garmin ECHOMAP™ Ultra 2 16” is a powerhouse chartplotter and sonar combo designed for serious anglers who want clarity, capability, and confidence on the water. With a vibrant 16-inch full HD touchscreen and keyed assist controls, this unit gives you sharp visuals and intuitive navigation — even when conditions turn rough. Whether you're chasing bass in the shallows, targeting structure offshore, or scanning for bait balls, this unit delivers everything in stunning detail.

You’ll get CHIRP traditional sonar for crisp target separation, plus Ultra High-Definition ClearVü™ and SideVü™ scanning sonar that paints a photo-like image of what’s happening below and to both sides of your boat. Transducer required and sold separately. Want live-scanning sonar? The ECHOMAP Ultra 2 is fully compatible with Garmin’s LiveScope™ series (sold separately), so you're ready to upgrade any time.

The 166sv's navigation capabilities are just as strong as its sonar. This model comes preloaded with Garmin Navionics+™ mapping, giving you detailed coastal and inland coverage with 1’ contours, daily updates, depth shading, and more — plus the option to upgrade to Vision+™ for satellite imagery and advanced relief shading. Built-in multi-band GPS provides fast, reliable positioning accuracy even in tough environments like bridges, trees, or steep banks.

Connectivity is top-tier. You can wirelessly share sonar, routes, and waypoints with other compatible Garmin units onboard. There’s full NMEA 2000® support for integration with your autopilot, heading sensors, or Fusion audio. Use Bluetooth® voice control to manage your Force® trolling motor, change views, or mark hot spots hands-free. The HDMI output is perfect for mirroring your screen to a second display at the helm or in the cabin.

The ECHOMAP Ultra 2 mounts cleanly with the included bail mount with tilt knobs, giving you flexible installation and easy removal. Pair it with the ActiveCaptain® app for software updates, screen recording, Quickdraw™ map sharing, and mobile control. From shallow backwaters to deep drop-offs, this unit gives you the tools, tech, and visibility to fish smarter — and land more.

The Garmin ECHOMAP Ultra 2 is equipped with (1) NMEA0183 input and output port, (1) 12-pin sonar port, (2) Garmin network ports, Wireless connectivity, and NMEA2000. Easily connect heading sensors, autopilot, digital switching, FUSION-Link and more!
