Experience an advanced all-in-1 solution with our 12-inch GPSMAP 1242xsv keyed combo. Includes transducer for Garmin CHIRP sonar, CHIRP ClearVü and CHIRP SideVü (also available without transducer). It also has built-in support for Panoptix all-seeing sonar and premium Garmin sonar modules (transducers sold separately). Features a large, bright screen coupled with quick and easy-to-use a keypad interface with user-progammable keys and a multi-function control knob.
Garmin Marine Network support allows sharing of sonar, maps, user data, dome or open-array radar, IP cameras and Panoptix™ sonar among multiple units. Includes NMEA 2000 network connectivity and NMEA 0183 support for 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.
Enjoy built-in ANT wireless connectivity directly to quatix® marine watch, Garmin Nautix™ in-view display, gWind™ Wireless 2 transducer, GNX™ Wind marine instrument and wireless remote controls.
Right out of the box, you have access to some amazing sonar capabilities; all you have to add are transducers. Comes with built-in Garmin 1 kW CHIRP sonar, CHIRP ClearVü and CHIRP SideVü scanning sonar. It even supports Panoptix all-seeing sonar, premium Garmin sonar modules and a wide range of transducers (sold separately).
Networked combos can share their internal sonar with any other device on the network. You can also choose what information is overlaid on the sonar screen; for example, radar, time of day or GPS speed.
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.
You get both LakeVü HD inland waters mapping and BlueChart g2 HD coastal charts.
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 fishing charts. It also transitions smoothly between zoom levels and delivers seamless continuity across chart boundaries.
Two SD™ card slots provide expandable memory for accessory map purchases, such as LakeVü HD, LakeVü HD Ultra, BlueChart® g2 HD or 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.
