What sets this setup apart? Its ability to weave sonar, charts, radar, and engine data into one cohesive experience. Whether you're dodging fog banks or hunting trophy bass in shallow coves, this system adapts to your needs without overwhelming you.
Touchscreen Chartplotter and Fishfinder Excellence
The 12-inch sunlight-readable touchscreen responds effortlessly, even with wet hands or gloves, making it a joy to use from dawn patrols to dusk runs. Dive into preloaded BlueChart g3 coastal charts and LakeVü g3 inland maps, enriched with Navionics data for unparalleled detail. Auto Guidance technology plots efficient paths around obstacles, saving you time on trip planning.
- Superior Sonar Capabilities: Built-in 1kW CHIRP traditional sonar delivers sharp fish arches and bottom contours. Add ClearVü and SideVü scanning for photorealistic views under your boat, or go all-in with Panoptix all-seeing sonar—including the game-changing LiveScope for live-action fish tracking.
- SailAssist Tools: Laylines, enhanced race timers, set/drift calculations, and wind overlays help racers and cruisers optimize every tack and jibe.
- Engine and System Integration: J1939 connectivity links seamlessly with Yamaha engines and third-party devices via OneHelm, while NMEA 2000/0183 and Garmin Marine Network let you share data across multiple screens, autopilots, cameras, and sensors.
Pair it with ANT-enabled Garmin watches or wireless remotes for hands-free control, and use the ActiveCaptain app to update charts, plan routes, and access community insights from your phone—anywhere with signal.
GMR 18HD+ Radar: Compact Power for Unmatched Awareness
For boats where space is at a premium, the 18-inch GMR 18HD+ dome radar packs 4kW of transmit power into a low-profile design. It paints vivid, color-coded echoes up to 36 nautical miles, helping you spot birds, buoys, and boats long before they become problems.
- Smart Auto Adjustments: Dynamic Auto Gain and Sea Filter tune themselves to wind, waves, and weather, ensuring clutter-free images without constant tweaking.
- Overlay and Tracking: Superimpose radar on your charts for intuitive situational awareness; add a heading sensor for precise MARPA auto-tracking of up to 10 targets.
- Proven Specs: 5° horizontal by 25° vertical beam, 20-meter close-in detection, and 24 RPM rotation deliver reliable performance in rain, fog, or night ops.
Installation is straightforward—no endless menus or pro tools required. Mount it high, connect via the included cables, and you're scanning the horizon in minutes.
Build Your Dream Helm: Connectivity That Expands
This combo shines in networked setups. Dual Garmin Marine Network ports share user data, radar overlays, and IP camera feeds across units. One 12-pin transducer port handles multiple sonar types, while video inputs/outputs support BNC cameras and HDMI to external displays. Wireless connectivity opens doors to media players, VHF radios, AIS receivers, and weather modules.
Real-world tip: For offshore fishing trips, link it to an autopilot for radar-guided hands-off cruising, or integrate digital switching for one-touch control of lights and pumps. Anglers love stacking LiveScope with SideVü to map structure and watch baitfish reactions simultaneously.
Ready-to-Install Kit for Quick Setup
Everything arrives primed for action: the chartplotter with bail/flush mounts, power/adapter cables, and protective gear; the radar with hardware, 15m power/network cables, and templates. Spend less time wrenching, more time boating.
Pro Tips for Maximizing Your Garmin Experience
To get the most from your investment:
- Calibrate transducers post-install for accurate depth and fish ID.
- Customize split-screen views—radar/chart/sonar in one glance.
- Leverage ActiveCaptain for over-the-air updates and OneChart subscriptions.
- For sail racing, enable wind holds and polar tables via compatible sensors.
Boaters report fewer close calls and bigger catches thanks to this system's real-time fusion of data—it's like having a crew of experts onboard.
