    Nice article Ben,
    a question: in your side by side comparison, and in a few other screenshots, the HD seems to bloom more in distance and the Quantum more in angle.
    Is that a function of the settings or part of the basic design?
    For example, in the first image all of the returns looked like side shots of boats, that were all pointing in concentric circles. If this is an artifact of a small antenna, it makes sense.

  2. jak says:

    I was wondering if any of these vendors are considering producing a smaller antenna for racing sailboats? It seems like recent gains might offset the losses from a downsized rig.

  3. Ben Ellison Ben Ellison says:

    Jak, I’m not sure there’s enough market to warrant a much smaller solid-state radar but it certainly seems possible to build one.
    And note that the current Quantum with WiFi data connection could be pole mounted on a sailboat in such a way that it would be pretty easy to stow it when not needed.

    I have left feedback for Furuno on both their forum and every trade show that I have seen them.
    An open array with NXT technology would get me off the fence about upgrading from a 4kw dome. With the NXT costing a few $100 less than the 4kw dome, it is a tough pill to swallow. I could see myself keeping the 4kw dome if I could add a 3.5′-4′ open array.
    Furuno is always tight lipped, has their been any indication they might expand the line?

    Ben, can you please make some comparison shots between Quantum and 4G before you move the Quantum? Screen shots from the same position with identical ranges at almost same time from both radars at short, medium and long ranges would be very interesting.

    A very helpful Garmin product/sales guy at Southampton Boat Show told me that Fantom radome will ship early December. In 18 & 24.

  7. Ben Ellison Ben Ellison says:

    Howard, at least for now Furuno seems determined to stay with magnetron open arrays and they’re making big claims for the new DRS6A X-Class:
    No worries, Abbor, I have already started comparing Quantum and 4G from same spot.
    And, Mark, won’t that be great news in solid-state Dobbler marine radar evolution if it’s true?

  8. Howard says:

    Followed up with an inquiry to Furuno in Camas, Washington. I am going to visit Furuno for a operational hands on with a DRS6A X lass radar.
    The tracking features are intriguing. I have yet to determine if it is compatible with Maxsea Timezero.

  9. Howard says:

    Another note, Timzero /Nobeltec is not compatible yet with NXT or the DRS6a X class yet. A software release is due later this year.

    On return trip from Newport,RI boat show aboard my new Bruckman Abaco 40, I had a great time with the installed Furuno NXT radar. On Tuesday from Sandwich, MA at end of Cape Cod Canal, it was “pea soup” fog almost the whole trip back to Harpswell, ME (Great Island Boat Yard, who installed the electronics).
    With the NXT tied to the Furuno 15″ TZ Touch 2, the display was nothing short of AMAZING. Especially with all the AIS targets displayed both on the charts, and on the NXT. The “tracking” function that turned targets RED if they were a danger, worked very well. Going across the shipping lanes into Boston, proved to be very satisfying.
    When we got to Green #3 at the turning point towards Great Island Boat Yard (from the Gulf of Maine) , Fog was so thick I could not even make out #3 only about 100 feet to my port side. This is a small slot that brings you past rocks on the port side and rocks / Island on the starboard side.
    With the NXT radar, and TZ Touch 2 displaying GOVT Raster Charts, I felt very comfortable. Even though this was the first time aboard BELLA & running this route.
    I did have my co-piot watching BELLA on “i-Sailor” displayed on a large Apple i-Pad. (I think best Navigation App out there, and the BEST charts for sure) as we went thru the cut. Told him “make sure I do not do something stupid” !!!!

    I was at mets today and yesterday and I saw hummingbird has a new radar and looks just like the quantum from raymarine
    Top and Base plate are similar. . .

  12. Ben Ellison Ben Ellison says:

    You are correct, Tcy! Yesterday, a great source sent me the link below, which seems to show that Raymarine has applied for FCC approval of a very Quantum-like radar that will be badged “Humminbird CHIRP” (model HB 2124)
    I think it’s good news. With four major brands already competing to make the best solid-state radars, we probably wouldn’t benefit from more. But now Humminbird customers will have access to solid-state radar tech and Ray will have more resources for R&D. All good.

    Hi Ben,
    I know that Quantum has the hardware to do automatic target analyzing using Doppler Effect like Furuno NXT, but so far no one was able to tell me if Raymarine is actively working on that feature. Do you have insights on that topic you can share?

  14. Ben-
    Is it likely that Raymarine will make a software update to the Quantum 24 or will they not add Doppler until a new open array comes out? I am going to upgrade to Axiom 12 early 2018 but then my serviceable old magnetron Raymarine will be incompatible with the new Axiom display. I’d like to have targets show up in color with Doppler showing a threat to us. It is very hard to keep heads down when navigating Rosario, Haro or Georgia Straits out here. LOTS of heavy traffic and still more small fishing boats running 30Kts and really posing a threat in foggy weather.
    Its been 9 years since Honeywell demonstrated a SS pulse compression radar near the San Juan Islands – a LOT has passed by.

  15. Ben Ellison Ben Ellison says:

    Good to hear from you again, Dave, but sorry I don’t know where Raymarine is at with Doppler radar development. I imagine that all the big brands are working on it, with Furuno NXT motion highlighting and ARPA performance the target. And rumor has it that a Furuno NXT open array will appear very soon. Also, existing Simrad Halo radars will get its Velocity Track Doppler optional feature quite soon, and it looks good in screens I’ve seen. Meanwhile, Quantum remains a very solid radar for the money in my opinion.

  16. Jim says:

    In your experience, will the Ray Quantum pick up any floating debris, like logs, tires, etc. in flat water?
    On YouTube, there is a vid of a 4Q picking up a floating tire, though it still had the steel rim attached.
