Garmin GPSMAP® 1242xsv Plus Touchscreen GPS/Fishfinder Combo

Garmin GPSMAP® 1242xsv Plus Touchscreen GPS/Fishfinder Combo Product Description

Transform your time on the water with a chartplotter that puts precision navigation and crystal-clear fishfinding right at your fingertips. This powerhouse device blends a vibrant 12-inch touchscreen with cutting-edge sonar tech, making it a go-to for serious anglers, cruisers, and sailors who demand reliability in rough seas or calm bays. Whether you're plotting a coastal run or hunting trophy fish in deep water, its seamless integration elevates your entire boating setup without the clutter of extra screens.

Superior Navigation with Preloaded Coastal and Inland Charts

Hit the water confident with detailed BlueChart g3 coastal charts and LakeVü g3 inland maps right out of the box. These aren't just basic outlines—they pack Garmin and Navionics data for spot-on detail, including marinas, hazards, and points of interest. The Auto Guidance feature simplifies route planning by suggesting safe paths around shallows and obstacles, saving you headaches on unfamiliar waters. Anglers love customizing Quickdraw Contours to map their own hotspots, turning every trip into a personal chart-building adventure.

For those chasing upgrades, optional premium charts layer in high-res satellite imagery and relief shading, helping you visualize underwater contours like never before. Real-world tip: Zoom in on wrecks or drop-offs during scouting runs to pinpoint prime fishing zones before the bite turns on.

Advanced Sonar for Unmatched Fishfinding Clarity

Dive deep into what's below with built-in 1 kW CHIRP traditional sonar that separates targets like baitfish from structure with surgical precision. Add ClearVü and SideVü scanning at up to 260 kHz, and you can peer 1,000 feet around your boat—perfect for mapping reefs or spotting schools hugging the bottom. For live-action views, pair it with Panoptix or LiveScope transducers to watch fish react in real time, giving tournament pros the edge they've been craving.

• CHIRP frequencies: 50/77/83/200 kHz for versatile coverage
• Max depth: Up to 5,000 ft, depending on conditions
• Bonus features: Bottom lock, water temp graphs, sonar rewind for replaying scans

Pro anglers swear by SideVü for its wide swath, revealing hidden ledges that traditional sonar misses. Pair transducers easily via the 12-pin port and adapter included.

Build a Connected Helm with Effortless Networking

Why stop at standalone? Link up via Garmin Marine Network to share maps, radar overlays, and IP camera feeds across multiple units. NMEA 2000 and 0183 connect autopilots, VHF, AIS, weather stations, and FUSION audio for one-screen control. J1939 engine data pulls RPM, fuel, and trim from Yamaha or others, while OneHelm unifies third-party gear like digital switches.

ANT+ pairs with quatix watches or wireless remotes for hands-free operation, and built-in Wi-Fi hooks into the ActiveCaptain app. From your phone, access software updates, community Quickdraw data, or smart notifications—keeping your system sharp without docking.

Intuitive Touchscreen Built for Real Boating Demands

The 12.1-inch diagonal WXGA display (1280x800) shines even under direct sun, with glove-friendly touch controls that respond in choppy conditions. IPX7 waterproofing shrugs off splashes, and mounting options—bail or flush—fit any console. At 5.8 lbs, it's sturdy yet manageable for installs.

Sailors get SailAssist tools like laylines, set/drift, and wind overlays for tactical racing advantages. Customize SmartModes for fishing, cruising, or anchoring views tailored to your style.
