Raymarine Axiom 2 7 RV Chartplotter with RealVision 3D Sonar E70721

The Raymarine Axiom 2 7 RV, part number E70721, is the all-in-one version of Raymarine's most popular 7-inch display, sold as a base unit so you can add the charts that fit your waters. If you fish somewhere specific, or you already own a LightHouse chart card, buying the plotter without a preloaded regional bundle keeps your money where it counts. You get the full-featured display and sonar, then match the chart region to where you actually run the boat.

The RV in the name is what sets this model apart. It has RealVision 3D sonar built right into the display, along with SideVision and DownVision, so there's no separate sounder module to buy or find space for. RealVision 3D renders the bottom and everything on it as a photo-like image you can rotate and read at a glance. SideVision scans wide to either side of the boat, which is how you spot bait and structure you'd otherwise motor right past. DownVision gives you that crisp, near-photographic view straight down. Add high-CHIRP and conventional CHIRP channels and you've got a serious fish finder that's also a full chartplotter. You'll want a compatible RealVision transducer to unlock the sonar, connected through the 25-pin transducer port.

For navigation, the display fixes its own position with a fast internal GNSS receiver that tracks GPS, GLONASS, and Beidou satellites and updates ten times per second, so your boat icon stays glued to your real track through hard turns and busy harbors. You can store up to 10,000 waypoints, 250 routes, and 15 tracks, which is plenty for a full season of fishing spots, anchorages, and the runs you make over and over. Load your preferred LightHouse charts on a microSD card and you're ready to plan and go.

The screen is a 7-inch IPS panel at WSVGA 1024 x 600, rated at 1800 nits, and that brightness is what keeps it readable under a high sun with polarized glasses on. IPS gives you wide viewing angles, so it still looks right when you're steering from the side of the helm. Raymarine's HydroTough oleophobic coating helps the glass shed spray and resist the greasy fingerprints that build up over a day of running. Under the glass, a fast 6-core processor and the LightHouse operating system deliver up to 30 percent quicker chart redraws than the previous generation, so panning and zooming feel smooth rather than laggy.

Networking is a real strength of the Axiom 2. Gigabit RayNet Ethernet lets you tie in radar, additional sonar modules, thermal cameras, and more Axiom 2 displays, so a single-screen boat can grow into a full multi-station helm later. NMEA 2000 support brings engine data to the screen, so you can watch RPM, fuel burn, and tank levels alongside your chart and sonar. Built-in Wi-Fi and Bluetooth handle software updates, app integration, and wireless route sharing from a companion planning app. There's a microSD slot for chart regions and backups, plus 64 GB of internal storage.

It's built to live on an open helm. The sealed housing carries IPX6 and IPX7 water ratings, so heavy spray, rain, and washdowns don't bother it. It draws under 10 watts and runs on standard 12-volt DC with an 8 to 16 volt operating range. Mounting is flexible, with both trunnion bracket and flush mount options, so it drops into a console cutout or a helm pod cleanly. The trunnion footprint is roughly 250 mm wide by 163 mm tall, and the flush cutout is more compact at about 201 by 133 mm.

If you run a center console, a bay boat, or a bass rig and you want navigation and serious sonar from one 7-inch screen, but you'd rather choose your own chart coverage, this base RV model is the one to look at. You get the same premium display, processor, sonar, and networking as the preloaded bundle, just without a chart region you might not need. Pair it with the right RealVision transducer and the LightHouse charts for your home waters, and you've got a helm that finds fish, marks structure, and gets you home, all from one bright, confident display.
