Raymarine Magnetic Sun Cover for Axiom2 XL 16in (A80733)

That 16-inch Axiom2 XL is one of the biggest, brightest glass helms Raymarine builds, and the screen is the most expensive real estate on your dash. This magnetic sun cover, Raymarine part A80733, is the factory-made shield that keeps it safe when the display's off. It's molded specifically for the Axiom2 XL 16, so it sits flush across the glass and bezel with no gaps, no sag, and no guesswork.

The whole point here is how easy it is to use. Magnets are built right into the cover, so it snaps onto the front of the display and pulls off just as fast. No straps to thread. No snaps to line up. No clips that crack after a couple of seasons in the sun. You walk up to the helm, peel it off, and you're running. When you're done for the day, it goes back on in about two seconds. That convenience matters more than it sounds, because a cover that's a pain to put on is a cover that stays in the cabinet while your screen bakes.

And baking is the real enemy. UV is brutal on marine displays. Leave a screen exposed at the dock all summer and you're inviting fading, haze, and heat stress on the bonded glass. Add in dust, pollen, salt spray, and the film of grime that settles on everything at a marina, and an uncovered display ages fast. This cover blocks all of it. Sun, dust, salt, and dock dirt stay off the glass, so the screen you paid for still looks and works like new years down the line. A clean, un-hazed screen also reads better in bright sun when you actually need it, which is the whole reason you bought a big glass display to begin with.

It's made from silicone, which is the right call for a part that lives outside. Silicone stays flexible when it's cold, doesn't get brittle the way cheap plastics do, and wipes clean with a damp rag. It flexes over the bezel and holds its shape, and it shrugs off the temperature swings a boat sees between a July afternoon and a frosty spring launch.

One thing worth knowing before you install it. The cover contains magnets, and Raymarine notes that those magnets can interfere with magnetic-sensitive gear like compasses, attitude sensors, and gyroscopes. So when the cover comes off, don't set it down right next to your compass or an AHRS sensor. Toss it in a cabinet or a drawer instead. It's a small habit, and it keeps your heading data honest.

Who needs one? Anybody running an Axiom2 XL 16. If your boat sits on a trailer, at a mooring, or on a lift between trips, this is cheap insurance for a pricey display. It's just as useful on a flybridge or an open center console helm where the screen faces straight up into the sun. Slip it on before you cover the boat, before you trailer home, or any time the electronics are going to sit for a while. Off-season storage especially. A display that spends the winter under this cover comes out in spring clean and clear.

Because it's a genuine Raymarine accessory built to the exact dimensions of the Axiom2 XL 16, you don't have to worry about a universal cover that almost fits. It's the right size, the right shape, and the right magnets in the right spots. If you've got a different Axiom2 XL, say the 19-inch, you'll want the cover sized for that model instead. This one's for the 16, and it's about the simplest, cheapest thing you'll ever do to protect a serious display. Snap it on, walk away, and stop worrying about what the sun's doing to your helm.
