There is understandable grumbling about how Raymarine's new 7-, 9- and 12-inch Axiom multifunction displays shipped (somewhat late) without several significant features that Ray plans to deliver with a software update at a yet unspecified date. But I'm fairly confident that the longer term story is rosy. After two days of fishing with beta MFDs in Florida and installing a test Axiom 7 myself, I'm impressed with both the hardware and the new LightHouse 3 interface, and I'll be surprised if the missing features and more don't fill in nicely. Let's take a glass-at-least-half-full look at this major product line change...

As discussed when launched with bam!, an optional but major new feature of the Axiom MFDs is support for new RealVision transducers capable of four different CHIRP-assisted sonar modes -- all at once if you'd like. That was all working pretty well in Florida. What you're seeing on the Axiom 9 and 12 displays above are fishfinding, DownVision, and RealVision 3D windows, and while the SideVision window was not visible on either boat at the time, the side looking data is being used to "skin" the 3D model of the bottom while also highlighting targets separate from the bottom, be they fish or turbulence created by the boat.


On the Axiom 12 display immediately above, Captain Chris Williams is blasting along beautiful Lake Rousseau at 27 knots, but all three sonar modes are still holding bottom, and I can testify that neither the sonar nor the internal GPS tracking seemed to lag behind the boat's speed even a bit. Axiom is notably fast in all ways. But you may also notice, perhaps with a shudder, how shallow the channel was, and that's in a flooded lake full of dangerously shallow trees (the same Navionics map detail here), which did not add up to a good sonar testing situation. In 5 feet of water, no sonar can see much in any direction.

Fishing way out in the Gulf of Mexico with Captain TJ Shea (whose seamanship skills already impressed me one night in Naples) was a better opportunity to see the multimodal RealVision in action, though still not ideal, simply because the bottom is so flat out there. Many of the hotspot waypoints that fishermen covet in these waters turn out to be minor bumps that show best in the regular fishfinding mode with its color coding of bottom hardness. It was impressive, however, that the Axiom 9 color CHIRP fishfinding seen from the RealVision transom transducer on Shea's Southport 33 mirrored almost exactly what was happening on his big Ray screens with black box sonar processing and a much more expensive transducer (and perhaps it will be better in some situations once the RealVision transducer's built-in gyro stabilization is enabled).


While the Axiom 3D and fishfinding images in the collage above are giving different perspectives on real fish being caught by enthusiastic boating writers, there are many other situations where the 3D, side and down views will have more value, like around this UK wreck. And in those situations I believe that users will be quite pleased with how easily they can set up and tune the sonar imagery using LightHouse 3 interface screens like the two shown. But do not presume that Axiom or LH3 are just about fishing.

While I suspect that we'll soon be seeing more evidence of good fishing performance from the various Axiom displays with built-in sonar processing, that's only part of the story. For instance, Steve Mitchell just installed a plain Axiom 9 on his Beneteau 311 sailboat and is impressed with many non-sonar aspects of the MFD. Also, owners of most Raymarine MFDs sold in recent years can purportedly look forward to a major software update that will deliver LightHouse 3 interface niceties like the ones Steve illustrates well and like I collaged above. Judging interfaces is subjective, but I'm certainly "getting" LH3 quickly and also loving how often the effect of adjustments can be seen live as you make them.


But like other early Axiom owners, Steve is anxious to see LH3 acquire features like the Navionics Dock-to-dock autorouting that came to LH2 R17 last year, and anyone installing Axiom now should be very careful about their expectations. Some currently missing features are noted on the Axiom model pages, and there are also numerous Axiom discussions on the Raymarine support forum, but perhaps the most complete summary is Jim McGowan's Panbo comment here.

It's good to look at the rear end of an MFD because that's where you see the connectivity that largely sets them apart from standard computers, mobiles, and sometimes each other. So there's the big 25 pin port that handles all those RealVision sonar modes (and is also backward compatible with Ray's CPT-100 DownVision transducers), and next is an unusual port for an included cable that splits for 12v power and NMEA 2000 networking (with a standard N2K male connector, not a SeaTalkNG "stub" connector).


I suspect that the power and N2K functions were combined to make room for that micro USB port that does look like what you may have on your phone (or camera). I haven't seen detailed documention yet, but it certainly seems to be a versatile USB On-The-Go (OTG) port, which means it can support both "slave" and "master" relationships. In fact, I purchased an OTG adaptor and verified that this Axiom 7 can use either USB memory sticks and SD cards cabled to this port. The official Axiom A80440 Remote Card Reader doesn't seem available yet, but I trust it will have an outer threaded connector to waterproof the port and it may also include its own USB port.

Finally, at left is the RayNet-style Ethernet port that can connect Axioms to various Raymarine radars, sonars, and IP cameras. Axioms can also be networked to each other, but apparently not to older Ray MFDs until the latter can be updated from LightHouse 2 to LH 3.

This photo shows the micro SD card slot on the back of the Axiom along with its waterproof cover (and that split power/N2K cable). I grinned when I tried the hard plastic suncover. Raymarine once provided soft covers that looked good but did not always stay put (in my experience), but it will take a hurricane to dislodge this new cover design. However, it only works if the Axiom is installed in its included bracket mount.

This test unit is the full $1,350 Axiom 7 RV model with the RV-100 transducer and a Navionics Nav+ card for all of the U.S. and Canada, but the base model without sonar and only U.S. NOAA vector charts is $650. I've already seen the Axiom display an older set of LightHouse NOAA raster charts, but I'm not sure it can work yet with the $10 regions available at the Raymarine Chart Store. Also, I wouldn't hesitate a second to spend an extra $50 for the 8 gigabyte Navionics card which comes preloaded with all those charts (and many lake maps) and still had room to add SonarCharts and Community Edits from Maine to South Carolina. It was also easy to update all those charts with the online Navionics app and the card includes a year of updating.

I do hope that LightHouse 3 will eventually work with C-Map charts like LH2 does -- particularly the 4D Max+ chart bundles that include a raster layer for most countries -- but let's acknowledge that a lot of software coding is involved when you're pretty much starting from scratch with a new base operating system (Android), which apparently is the Axiom/LH3 situation.

Also, a word on Axiom prices: Like some other marine electronics companies -- it's looking like a trend -- Raymarine seems to have adopted minimum pricing, which is different from manufacturer's suggested retail pricing or even minimum advertised pricing. It's Apple-like what-you-see-is-what-you-get pricing. So while Axiom prices look like a good value to me, you should not mentally knock off a chunk of change you think you'll see as a discount from some sources. For instance, the Axiom 7 prices listed at Raymarine are the same prices you'll see in a Defender shopping cart. I tentatively view this as a good trend that encourages quality distribution but I may not understand all its ramifications.

Back to suncovers, I don't know how one can possibly secure to the all-glass face and shallow bezel of a surface-mounted Axiom, but that face sure is sleek and bright. Note here that at full 1200 NIT display brightness -- which I saw working fine in high direct Florida sunshine -- this Axiom 7 is only drawing 8W of power (or 0.7a at the 11.5v coming from the half-charged long test Weego). In my experience, that draw will drop noticably with a click or two of screen dimming and remember that a quad core processor, 4GB of solid state memory, and a high spec GPS are also being powered.


I was (unreasonably) hoping that in this faster-better-cheaper tech world the Axiom GPS would locate itself for the first time on the photo table deep in my basement shop, but it did only take a minute or so just outside. And look at all the GMDSS satellite systems it can use, as well as the sort of well explained and illustrated settings screen I keep happily finding in LH3.


Also impressive is the Axiom surface mount scheme. If you look at the backside photo above you'll see four allen head bolts that allow the whole outer shell to slip off. Then you attach the four brass studs, place the Axiom in the right size whole, and the shell becomes a strong all-away-around-back clamp with no surface screws penetrating the glass face, plus no screw covers to lose or a thin removable bezel to break.


Before replacing the aSeries WiFi a78 (with the silver removable bezel I painted black in search of the glass bridge look), I took these comparison shots. The Axiom 7 model with DV sonar and transducer is directly comparable, yet a noticably better build with a lot more horsepower at a similar price. And using a touch interface is a lot easier when your fingers don't jam against the edges of the screen, and also when it responds much faster.


Remember, though, that right now Axiom WiFi and several other built-in capabilities cannot do what an a 78 running LightHouse 2 can. Also, be aware that this first Axiom series is pretty clearly a replacement for the aSeries, and that Axioms with hybrid controls and a larger choice of screen sizes seems inevitable. In fact, a Panbo reader reports hearing that they'll be called the "Axiom Pro" series and will be out "in a very few months."

The Axiom 7 cut out is slightly smaller than the a78's, but I disguised the difference fairly well with some thin black PVC sheet. I also temporarily hooked up a Cam220 IP dome camera largely to see if it would work cabled directly to the Axiom's RayNet port instead of to the RayNet switch that both will eventually network to along with the eS12 on the flybridge. It did, without any setup on my part, and notice how I can turn the streaming video into a snaphot (like below) or a video recording. I can also give the camera a custom name and icon and, most impressively, run at least three more IP cameras on the network.

I've got a lot more testing to do, but it seems like the case can be made that the Axiom series as is right now would make a heck of a camera network with a good chartplotter and radar display thrown in, and lots more very likely to come.
