Raymarine Quantum 2 doppler radar without heading sensor

[RaymondR]

I run a Raymarine dopler radar without any external heading sensor with an Axiom 9 MFD and use the radar over chart overlay.

Since I have an autopilot with only nmea0183 I use an 0183 to 2000 converter to allow the autopilot and MFD to communicate.

They say with an adapter, I think they mean the seatalk 1 to NG one from raymarine.



I think i am facing the same issues here…

Want to replace my old hd218 Raymarine with the old chartplotter with a new radar and chartplotter.

I have now Raymarine e7 mfd at the helm, Raymarine adapter seatalk1 to NG, the older ST6001+ Autopilot with S2G and lineardrive Typ 1.

Happy with the setup, just want a new radar with doppler.



Plan was to get an Quantum 2 radar and an axiom 7+ at the helm (cannot fit a bigger one) and put the older e7 at the nav station. Would Use RayRemote with iPad 12.9 anyhow to remote stear the axiom 7+.

Questions

1) First will that work or do I need to use the axiom 7.

2) for the heading, do I really need the 700$ ev1 heading compass or is there a much cheaper alternative available that has 10Hz and is enough for the Marpa to work?

If not maybe B&G Zeus 3 and their radar is the better choice, the Zeus 3 has a 10Hz compass integrated and would also work with my old Raymarine. Are there any downsides to this.



I am not looking into a major refit of my existing old but proven Raymarine setup.

Yes there is always something better….I like the simplicity of this older Raymarine and a lot went around the world with them.

Just wanna add a good radar with doppler as cheap as possible to what I have.

I think this info is wrong the latest Axiom has only nmea 2000 interfaces

Yep, I have two of them and both are only N2K.

In addition to the 0183 to N2K adapter I also have a Seatalk to Seatalk NG adapter to allow the Axiom 9 to talk to my Raymarine Wheelpilot backup autopilot.

Between Raymarine, Coursemaster and Simrad I have a small fortune invested in adapters and adapter cables.

which would be the cheapest 10hz heading compass with quantum 2 radar that would give me the full marpa functionality ?

If you want nmea2000 and 10hz you’re looking at $250-350

Digital yacht
Maretron
Futuna
B&G
Ray marine
Autononnic

What is the Raymarine heading sensor product in the under $350 price range. I was only aware of the EV-1 at almost $700 after taxes

Sorry I forgot they discontinued their fluxgate , but it’s still widely available

Which way did you guys looking for a compass end up going? I’m in the same boat now; I have an Axiom + and I’m adding a quantum 2 radar. For full functionality I need a compass, but the EV-1 seems to be overkill right now (and more $).

I will get the new Orca Core, it will cost around 500Euro but besides the compass (which is integtated/included) its a full blackbox that works as full chartplotter replacement in combination with a tablet. Orca is in final testing for the new core which can also work wit Quantum 2 radar.
Orca puts all data it gets from sensors on NMEA2000, so its avaliable for other sources too

So for 150Euro more i have a full 2nd backup of the Axiom which also works with radar with a 3rd charts ource besides Navionics and Transeat charts for Isailor.

That's it! My system is configured that way. My Quantum doesn't do auto MARPA alerts and auto target tracking as a result but I don't think I'm really missing much at least where I sail. The radar works great though and has heading data from the AP.

If have the old S3 autopilot with external Gyroscope sensor and the seatalk1 Fluxgate compass feading heading seatalk1 network and then via the raymarine seatalk 1 to NMEA converter into e7 chartplotter.
I was told thats old compass is too slow for Marpa on Quantum 2. Correct?
Still waiting for my axiom stuck in customs....that will replace the e7.

Well them you could spare yourself 500 bucks and get Quantum1 radar without doppler.
I got told the old seatalk1 fluxgate is too slow for Marpa.

That may be the way I go too. I was leaning towards the HSC100 from Digital Yacht, but then I’d need something like the Actisense gateway to convert to Nema2000; the combined price is getting close to the Core, and I’d end up with more capability. Decisions, decisions!
