Garmin GPSMAP 1242xsv Keyed Networking Combo – No Transducer

Discover Seamless Navigation with Advanced Chartplotter Technology

Imagine gliding across open waters with crystal-clear situational awareness at your fingertips. The Garmin GPSMAP 1242xsv delivers that precision through its expansive 12-inch WXGA display, combining vibrant visuals with intuitive keypad controls and a versatile multifunction knob. This setup shines in bright sunlight or rough conditions, where touchscreen alternatives might falter, ensuring you stay focused on the horizon.

Boaters rave about its fluid interface—programmable hotkeys let you customize access to essential functions like waypoint marking or sonar toggles. Whether you’re plotting a coastal cruise or chasing trophy fish in inland lakes, this unit transforms complex data into actionable insights.

Superior Mapping for Every Voyage

Outfitted with preloaded LakeVü g3 inland maps covering over 17,000 U.S. lakes at 1-foot contours and BlueChart g3 coastal charts infused with Navionics data, navigation feels effortless. Auto Guidance technology factors in your boat’s draft and overhead clearance to suggest optimal paths, helping dodge shallows and obstacles.

Enhance your setup with optional upgrades like LakeVü g3 Ultra or BlueChart g3 Vision for relief shading that reveals underwater terrain in stunning detail—think fish-holding drop-offs popping into view. Depth Range Shading and Shallow Water Shading provide at-a-glance safety cues, perfect for unfamiliar waters.

Powerful Sonar Insights Without Compromise

Unlock next-level fishfinding with built-in 1 kW CHIRP traditional sonar, CHIRP ClearVü for downward clarity, and CHIRP SideVü for wide-area scanning. Pair it with Panoptix transducers for live, real-time views ahead, below, and around your vessel—ideal for trolling or docking in low visibility.

CHIRP’s variable frequencies separate targets better than fixed sonar, spotting baitfish schools amid structure while minimizing clutter. Network sharing lets multiple screens display sonar overlays like radar echoes or GPS speed, streamlining crew decisions during busy outings.

Robust Networking for a Connected Vessel

Two Garmin Marine Network ports enable seamless sharing of sonar, user data, radar, IP cameras, and more across units. NMEA 2000 and 0183 compatibility integrates autopilots, VHF, AIS, weather stations, and digital switching—centralizing control from one helm station.

Wireless remote compatibility and GRID devices keep operations hands-free. Sailors benefit from synchronized race timers, laylines, and wind data synced across networked gear for tactical edges in regattas.

Stay Linked with Wi-Fi, ANT, and ActiveCaptain

Built-in Wi-Fi connects to the ActiveCaptain app, turning your smartphone into a trip planner. Prefish lakes, update charts, join the Quickdraw Contours community, or receive smart notifications—all syncing effortlessly to the plotter.

ANT+ links to quatix watches, gWind transducers, and Nautix displays for real-time data streaming. GPX imports from other devices mean your favorite spots transfer hassle-free, preserving years of hard-earned knowledge.

Lightning-Fast Positioning and Custom Maps

A 10 Hz GPS/GLONASS receiver refreshes position and heading 10 times per second, rendering smooth tracks for pinpoint waypoint drops (up to 5,000) and hairpin turns. Quickdraw Contours generates personalized HD maps with 1-foot contours on the fly—keep them private or share via Garmin Connect.

This zero-lag precision excels in marinas or high-speed pursuits, where every second counts.

Tailored for Sailors and Anglers Alike

SailAssist tools include pre-race pages with virtual start lines, burn time calculators, wind roses, set/drift indicators, and true/apparent wind overlays. For anglers, sonar history rewind and recording capture every moment, letting you analyze structure post-trip.

IPX7 waterproofing and versatile mounting (bail or flush) withstand spray and swells, while low power draw (under 35W max) suits extended adventures.
