Garmin GPSMAP 1242xsv Keyed Networking Combo - No Transducer w/GMR 18XHD Bundle — Product description
Discover Seamless Navigation and Radar Precision on the Water
Imagine gliding across open waters or navigating tight inland channels with crystal-clear situational awareness. The GPSMAP 1242xsv keyed networking combo paired with the GMR 18xHD radar bundle transforms your boat's helm into a command center. This 12-inch powerhouse combines intuitive controls, advanced sonar readiness, and high-definition radar scanning, all without the included transducer for flexible customization. Boaters and anglers rave about its responsive interface—perfect for gloved hands during rough seas—and its ability to network effortlessly with other gear.

It's not just equipment; it's your edge for safer, smarter outings.
Intuitive Keyed Control Meets Vibrant 12-Inch Display
The oversized, sunlight-readable color screen pairs with a rugged keypad and programmable multifunction knob, letting you zoom charts, toggle sonar views, or adjust radar gains without fumbling. Forget touchscreen frustrations in wet conditions—this design shines where precision matters most.
- High-sensitivity internal GPS/GLONASS for 10x-per-second position refreshes, smoothing out your trackline even at speed.
- Built-in CHIRP sonar support (transducer optional) with ClearVü, SideVü scanning, and Panoptix compatibility for live underwater vistas.
- Network sharing across multiple units: sonar, radar overlays, user data, cameras—you name it.
Pro tip: Overlay radar returns directly on your chartplotter for clutter-free collision avoidance, a feature that saves seconds in critical moments.
GMR 18xHD Radar: HD Clarity in a Compact Dome
Elevate your radar game with this 4kW, 18-inch dome that packs open-array performance into a familiar footprint. Its dynamic auto-adjustments handle calm harbors or choppy oceans, dialing in gain and sea clutter without endless tweaks. Split-screen dual-range views let you monitor close-quarters traffic alongside distant storms, all in rich 8-bit color.
- Intuitive modes for any sea state: Harbor/Offshore, Calm/Rough—pick your aggression level.
- 48 RPM rotation with auto-speed scaling for responsive sweeps.
- Effortless integration via Garmin Marine Network—no complex installs required.
Anglers love spotting bird flocks over bait balls; cruisers trust it for unmarked rocks or rogue waves. This radar doesn't just detect—it interprets the water ahead.
Stay Connected: From App to ANT and Beyond
Wi-Fi unlocks the ActiveCaptain app ecosystem: plan routes on your phone, crowdsource Quickdraw Contours from fellow boaters, or snag smart notifications without leaving the helm. ANT+ links to wearables like quatix watches or wireless wind sensors for real-time data fusion.
Full NMEA 2000/0183 compatibility hooks into autopilots, VHF, AIS, and more. Share one sonar source across the boat while video inputs display engine cams—it's a wired (and wireless) wonderland.
Superior Mapping: Own the Depths and Shores
Preloaded LakeVü g3 and BlueChart g3 blend Garmin precision with Navionics detail, including 1-foot contours on 17,000+ lakes and coastal raster charts. Auto Guidance plots safe paths around shallows; shading highlights depth zones to prevent groundings.
Upgrade to Ultra/Vision for relief shading that reveals submerged structures like never before. Best part? Quickdraw Contours lets you map uncharted spots in real-time, sharing or hoarding your secrets via the community.
For sailors, SailAssist tools like laylines, pre-race timers, and wind roses turn the screen into a tactician's dream.
Versatile Connections and Easy Setup
Two Marine Network ports, one 12-pin transducer slot, NMEA ports, and BNC video input ensure scalability. The bundle arrives ready to mount—bail, flush, or protected—with all cables and adapters included for plug-and-play vibes.
