Garmin GPSMAP742xs Plus Radar Pack with BlueChart US g3 with GMR18HD+ Radar

Discover Unmatched Navigation Precision on the Water

Imagine gliding through coastal waters or tackling inland lakes with confidence, knowing every twist and turn is mapped out in stunning detail. This powerful marine chartplotter pack combines a vibrant 7-inch touchscreen interface with advanced radar technology, delivering the tools serious boaters demand for safer, smarter voyages. Whether you're chasing trophy fish, plotting long offshore runs, or simply enjoying a day cruise, the intuitive controls and crystal-clear displays adapt to any condition—from blinding sun to rough seas.

Preloaded with coastal and inland charts that blend Garmin's renowned mapping with Navionics data, you'll benefit from Auto Guidance+ paths that steer you clear of hazards while highlighting prime fishing spots. Upgrading to premium charts unlocks even more, like high-res relief shading for spotting underwater contours that could mean the difference between a good day and an epic one.

Superior Sonar for Fish-Finding Mastery

Dive deeper into what's beneath the surface with built-in 1kW CHIRP traditional sonar, offering exceptional target separation to distinguish fish from structure. Pair it with ClearVü scanning sonar for down-to-1,000-foot clarity at 260 kHz, revealing the seafloor in photorealistic detail. For live action, connect compatible live sonar systems to watch baitfish schools swarm in real time—perfect for tournament anglers who need that edge.

Real-world tip: In murky bays, switch to SideVü (with optional black box) to scan wide swaths sideways, uncovering hidden wrecks or drop-offs without circling endlessly. Sonar history rewind lets you replay scans, marking spots on the fly for return visits.

Stay Ahead with HD Radar Vigilance

The included GMR 18 HD+ radome transforms your setup into a full-weather command center. This 18-inch, 4kW powerhouse delivers high-definition imagery up to 36 nautical miles, excelling at picking out birds, squalls, or rogue vessels even in clutter-heavy environments. Dual-range mode lets you monitor close-in traffic while scanning distant horizons simultaneously.

Pro anglers swear by its bird mode for locating bait balls from afar, while cruisers appreciate the rain cell discrimination that keeps you dry and on course. Seamless overlay on charts means radar data fuses right into your Navionics maps for intuitive threat assessment.

Build Your Dream Marine Network Effortlessly

No more siloed devices—this chartplotter shines as the hub of a Garmin Marine Network ecosystem. Share user data, maps, and radar feeds across multiple screens. Link to engines via J1939 for engine data like RPM and fuel flow, or integrate third-party gear through ONEHELM for unified control of digital switching, audio, and more.

Wi-Fi pairs with the Garmin app for smart notifications, community Quickdraw data (crowdsourced contours), and effortless updates. Control it all from a quatix watch or wireless remote while sipping coffee below deck. FUSION-Link audio, AIS vessel tracking, and VHF position sharing keep entertainment and safety dialed in.

Rugged Reliability Meets User-Friendly Design

Engineered for the harshest marine environments, its IPX7 water rating shrugs off submersion, while polarized sunglasses compatibility ensures readability in glare. Compact at 8.8 x 5.6 x 2.1 inches and just 2.4 lbs, it mounts via bail or flush for clean installs. 10Hz GPS/GLONASS receiver locks on fast for pinpoint positioning, even under heavy tree cover near shorelines.

Sailing enthusiasts get laylines, tide data, and wind overlays, turning this into a versatile all-rounder. Power draw stays efficient at 24W max, preserving battery life on extended outings.
