Garmin ECHOMAP™ Ultra 2 16" Chartplotter 166sv w/GN+ Mapping & GT56UHD-TM Transducer

Experience Unmatched Clarity on the Water

Imagine pinpointing your next trophy catch with crystal-clear visuals that cut through murky depths and cluttered charts. The Garmin ECHOMAP Ultra 2 16-inch chartplotter transforms your boat's helm into a command center for serious fishing expeditions. Its expansive full HD display delivers razor-sharp details, whether you're tracking baitfish schools or navigating complex coastlines. Anglers who demand precision swear by its ability to reveal hidden structures and fish-holding spots that smaller screens simply miss.

Superior Sonar Imaging That Reveals the Unseen

Paired with the GT56UHD-TM transducer, this unit unleashes Ultra High-Definition ClearVü and SideVü scanning sonars alongside CHIRP traditional sonar. Picture photo-like images of lake bottoms, drop-offs, and submerged timber—perfect for dialing in on bass ambush points or walleye humps. The vivid color palettes enhance target separation, making it easier to spot individual fish amid the clutter. For live action, it seamlessly integrates with LiveScope systems, giving you real-time views of fish reactions to your lure, a game-changer during competitive tournaments.

Advanced Mapping for Confident Navigation

Preloaded with Garmin Navionics+ charts on select models, you'll get daily updates, depth shading, and detailed coastal data right out of the box. Upgrade to Vision+ for even richer overlays like satellite imagery and custom shading. Multi-band GPS ensures pinpoint accuracy even in challenging environments, while wireless sharing lets you sync waypoints and routes across multiple units on your vessel—ideal for team fishing setups.

Smart Connectivity and Hands-Free Control

Stay connected without lifting a finger. Built-in Bluetooth supports voice commands for quick adjustments to trolling motor settings or sonar sources. HDMI output mirrors your screen to a larger display or salon TV for crew briefings. NMEA 2000 compatibility opens doors to autopilots, audio systems, and sensors, creating a fully integrated marine network. Pair it with the ActiveCaptain app to access community-shared Quickdraw contours, record sonar sessions for post-trip analysis, and handle updates effortlessly from your phone.

Rugged Design Built for Harsh Conditions

With an IPX7 water rating, this chartplotter laughs off spray, rain, and the occasional rogue wave. The IPS display maintains visibility from wide viewing angles, crucial during low-light dawn patrols or bright midday hunts. Bail or flush mounting options, complete with adjustable knobs, ensure a secure fit tailored to your boat's layout. At just under 10 pounds, it's substantial yet manageable for most center consoles and bay boats.
