- Key Facts
- Rating7.8/10
- Why this pickRaymarine no longer sells a plain 'Axiom 9.' Anyone searching that name today lands on the Axiom+ 9, which the manufacturer itself labels its previous generation next to the newer, pricier Axiom 2. The RV version is the one that actually functions as a fish finder, since the base Axiom+ 9 has no built-in sonar at all.
Pros
- One display covers CHIRP, DownVision, SideVision, and RealVision 3D, no separate sonar module to add
- 28-satellite GPS with SBAS holds position to roughly 5 meters, tight enough for marking structure and returning to it
- 1500-nit screen stays readable at noon on open water, where dimmer displays wash out
Cons
- The $1,349.99 price is for the display only; a real working setup with Raymarine's own RV-100 transducer runs $1,699.99
- Raymarine has already moved on to Axiom 2 as its current generation, so the Axiom+ 9 is a step behind the newest hardware Raymarine sells
- Bluetooth is capped at the older 4.0 spec, not the faster 5.0 now common on newer marine electronics
Search for "Raymarine Axiom 9" today and you won't find one. Raymarine's current lineup only sells this screen size under two names: Axiom+ 9, the previous generation, and Axiom 2 9", the current one. This review covers the Axiom+ 9, specifically the RV version with sonar built in, because that's the one that actually works as a fish finder rather than a bare chartplotter.

What "Axiom 9" Actually Means Right Now
Raymarine's own site sorts its chartplotters into two active families: Axiom and Element [F001 from hub research]. Within Axiom, the 9-inch size comes in two forms. Axiom+ is what Raymarine itself calls the previous generation, sold with or without built-in RealVision sonar. Axiom 2 is the current generation at the same 9-inch size, built on faster processing hardware. There's no bare "Axiom 9" sitting between them. If a listing uses that exact name, it's almost certainly referring to the Axiom+.
The plain Axiom+ 9, without the RV suffix, is chartplotter-only: no sonar, no fish-finding capability, just navigation. It runs $1,299.99, or $1,399.99 with LightHouse Charts North America preloaded. That's the wrong unit for this site's purpose, which is why the rest of this review, and the recommendation box above, covers the RV version instead.
"Axiom 9" today means Axiom+ 9, Raymarine's previous generation, and only the RV variant has sonar built in; the plain Axiom+ 9 is a chartplotter with no fish-finding capability at all.
The Sonar Is the Real Upgrade
The Axiom+ 9 RV adds 600 watts of sonar power split across CHIRP conical sonar, DownVision, SideVision, and RealVision 3D, Raymarine's real-time 3D bottom-imaging mode. That's the full modern sonar toolkit in one box: CHIRP for traditional fish arches, DownVision and SideVision for structure detail, RealVision 3D for a rotatable view of the bottom. What you don't get in the box is a transducer. Raymarine sells the display alone at $1,349.99, and its own RV-100 bundle, which adds the matching transducer, brings the real total to $1,699.99. Budget for the bundle price, not the display price, if you're pricing out a complete setup.
The 600W sonar suite (CHIRP, DownVision, SideVision, RealVision 3D) is genuinely complete, but the $1,349.99 sticker is display-only, the real all-in price with Raymarine's own transducer bundle is $1,699.99.
GPS and Screen: Solid, Not Class-Leading
The internal GPS tracks up to 28 satellites across GPS, GLONASS, and Beidou constellations, holding position to about 5 meters 95% of the time once SBAS correction kicks in. That's tight enough to mark a wreck or a honey hole and come back to the same spot. The 1500-nit display is bright enough for open water at midday, where cheaper 400-500 nit screens on budget units wash out to near-unreadable. Connectivity covers NMEA 2000 and Raymarine's own RayNet Ethernet for networking additional displays, plus Bluetooth 4.0 and Wi-Fi 802.11 b/g/n. The Bluetooth spec is dated. It works for pairing accessories, but it's not the faster 5.0 standard showing up on newer marine electronics.
GPS accuracy (~5m with SBAS) and screen brightness (1500 nits) are both genuinely solid for open-water use, the one dated spec is Bluetooth 4.0, not a dealbreaker but not current either.
Axiom+ 9 vs. Axiom+ 12
The Axiom+ 12 RV runs the same 600W sonar suite (CHIRP, DownVision, SideVision, RealVision 3D) on a larger 12-inch, 1280x800 screen at 1800 nits, brighter than the 9-inch's 1500. That extra screen real estate and brightness costs a real jump: $2,599.99 for the display alone, versus $1,349.99 for the 9-inch. Our full Axiom 12 review breaks down whether that's worth it for a bigger boat's helm. For most single-station setups, the 9-inch strikes a better balance between usable screen size and cost.
Sonar and GPS specs are identical between the 9-inch and 12-inch Axiom+ RV, the 12-inch's real advantage is a bigger, brighter screen, for nearly double the price.
Verdict: Is the Raymarine Axiom+ 9 RV Worth It?
Buy it if you want a proven sonar suite, CHIRP plus DownVision, SideVision, and RealVision 3D, on a display bright enough for open water, and you're comfortable that "Axiom 9" really means last generation's hardware rather than Raymarine's newest. Budget for the RV-100 bundle price ($1,699.99), not the bare display price, since the display alone won't find a single fish.
Skip it if you want Raymarine's current-generation processing (that's Axiom 2, not Axiom+) or you're working with a boat that can fit a 12-inch screen and would rather have the extra brightness and real estate of the Axiom+ 12.
Best fit is a buyer who wants the full sonar toolkit on a bright, mid-size screen and budgets for the RV-100 bundle price, not the display alone, skip it for current-generation hardware (Axiom 2) or a bigger helm (Axiom+ 12).
