Experience an advanced navigation solution with this compact 7-inch GPSMAP 742 touchscreen combo. Includes wireless connectivity features for Garmin mobile apps, NMEA 2000 support and Garmin Marine Network capabilities for radar and Panoptix FrontVü collision avoidance sonar.
Full-network compatibility allows you to add more capabilities to your boat. Garmin Marine Network support allows sharing of sonar, including Panoptix sonar, maps, user data, Garmin radar, and IP cameras among multiple units. Plus, there’s NMEA 2000 and NMEA 0183 support for connectivity including autopilots, digital switching, weather, FUSION-Link, VHF, AIS and other sensors.
Enjoy built-in Wi-Fi connectivity for BlueChart Mobile 2.0 and Garmin Helm apps. Garmin Helm allows you to view and control your compatible chartplotter from a compatible smartphone or tablet while providing enhanced situational awareness for the mariner. With BlueChart Mobile, a free app downloaded from the App Store™, you can get reliable weather information while you plan marine routes on your iPad® or iPhone® then wirelessly transfer them to your boat’s compatible networked Garmin chartplotter. You can even stream and control a VIRB action camera from the chartplotter.
Fast, responsive built-in 10 Hz GPS and GLONASS receiver refreshes your position and heading 10 times each second to make your movement on the screen more fluid. It makes dropping up to 5,000 accurate waypoints — and finding your way back to them — quick and easy.
LakeVü HD provides highly detailed freshwater maps that include 17,000+ U.S. lakes, rivers and reservoirs. Included in those are more than 13,000 HD lakes with 1-foot contours shoreline to shoreline. Upgrade to LakeVü HD Ultra with Max Def Lakes.
BlueChart g2 HD provides basic coastal charts, tidal stations, currents, depth contours, IALA symbols and includes fishing charts. It also transitions smoothly between zoom levels and delivers seamless continuity across chart boundaries.
Includes expandable memory for accessory map purchases, such as BlueChart® g2 Vision® HD, which adds Garmin patented Auto Guidance¹ and other great features.
Instantly create personalized HD fishing maps on-screen with 1-foot contours. Tailor them to fit your needs. These are your maps — you own them. Keep the data to yourself, or share it with the Quickdraw Community on Garmin Connect™.
To help you gain a wind-maximizing competitive edge, your chartplotter features a pre-race guidance page that shows your virtual starting line along with data fields showing laylines, time to burn before the start and a race timer that can be synchronized across all your networked Garmin GPS products. In addition, other supported sailing features include an enhanced wind rose, heading and course-over-ground lines, set and drift, true and apparent wind data and more.
If you have waypoints, tracks or frequently used routes stored on another manufacturer’s GPS product — or on a Garmin handheld device — it’s easy to transfer those items to your new Garmin chartplotter via industry-standard GPX software formatting.
