Garmin ECHOMAP™ UHD2 74CV Chartplotter/Fishfinder Combo w/US Coastal Maps & GT20-TM

Discover Crystal-Clear Views Beneath the Waves

Imagine gliding across coastal waters or inland lakes, pinpointing fish and structure with unmatched clarity. The ECHOMAP UHD2 74CV transforms your boating experience, blending a vibrant 7-inch keyed display with advanced sonar imaging that reveals every detail. Anglers rave about its ability to cut through murky water, making it a go-to for serious fishermen who demand precision without the hassle.

This combo unit pairs seamlessly with the included GT20-TM transducer, delivering dual sonar views that help you locate baitfish schools, wrecks, and drop-offs effortlessly. Whether you're chasing trophy bass in shallow bays or trolling for snapper offshore, its high-contrast color options ensure nothing slips by unnoticed.

Superior Sonar That Puts Fish on the Hook

At the heart of this fishfinder lies powerful Garmin CHIRP traditional sonar for wide coverage and exceptional target separation. Complementing it is ClearVü scanning sonar, which paints razor-sharp side and down images with improved resolution over previous models. The vivid color palettes elevate this further, using dynamic hues to highlight subtle differences in bottom composition and fish arches.

• Traditional CHIRP: Tracks multiple frequencies simultaneously for deeper penetration and finer detail.
• ClearVü Scanning: Down and side views up to 800 feet, ideal for structure fishing.
• GT20-TM Transducer: All-in-one unit with 500W power, medium CHIRP (150-240 kHz), and UHD scanning (455/800 kHz).

Pro tip: Adjust the color palette based on water clarity—opt for high-contrast on overcast days to spot suspended fish faster.

Navigate Like a Pro with Built-In Charts

Preloaded with detailed US coastal charts via BlueChart g3, this unit covers over 18,000 lakes with LakeVü g3 inland maps. Contour lines as fine as 0.5 feet on key lakes help you hug shorelines safely and target weed edges precisely. Support for Garmin Navionics+ adds depth shading, daily updates, and community edits for the freshest data.

Wireless sharing between compatible units lets your crew stay synced on waypoints and routes, perfect for multi-boat tournaments or family outings.

Stay Connected and Updated Effortlessly

Built-in Wi-Fi opens the door to the ActiveCaptain app, your command center for Quickdraw Community contours, software updates, and OneChart flexibility. Share sonar screenshots with buddies onshore or access Smart Notifications to keep your phone's alerts on the helm.

Networking shines in larger setups—pair up to five UHD2 devices wirelessly for a shared sonar black box experience, expanding your boat's capabilities without extra wiring.

Easy Setup and Rugged Reliability

Mounting is straightforward with included tilt and flush options, fitting kayaks, bass boats, or center consoles. The IPX7 waterproof design shrugs off splashes, and quick-disconnect cables make trailering a breeze. For optimal performance, position the GT20-TM transducer 1/3 aft from the transom, deadrise matched for minimal air bubbles.

Users love its intuitive keyed interface—no touchscreen glitches in rough seas. Battery life holds strong during all-day trips, and auto-gain sonar keeps readings consistent as conditions shift.

Real-World Wins from Fellow Anglers

From Potomac River stripers to Florida flats reds, this chartplotter has helped boaters land personal bests. One captain shared how ClearVü revealed a hidden ledge swarm with crabs and sheepshead, turning a slow bite into limits. Its edge over basic sounders? That vivid detail turns guesses into confidence.
