Tired of Bugs in Navico Equipment

It is quite possible that fmcw uses much less power in practice than their specs indicate.

Perhaps someone with one can do similar measurements?

Away from the boat for a few days playing Santa but will provide 3G realtime loads on my return.


Never use a hundred words when 3 will carry the message.

My 1A figure was the difference between standby and operation, so there is the magnetron heater to also add in. And I'm going completely by memory.

I think the older thread was started by Dockhead, and was about the 3G radar.

Pretty crappy day today so maybe I'll make some measurements.

Hi Mark,
I think this is the challenge with reviewing Nav electronics... it is always a moving target as things change so fast

I have been monitoring these discussions for the last 3 years as my refit kept getting delayed and I held off on MFD and new Radar till last minute.

I will be ordering January 4th and here are my thoughts.

1...Sticking with Furuno as world wide service and parts, especially in Asia is great.

2...The cockpit is the primary watch keeping and piloting station, so that is where the MFD TZTouch2-15 will live with the overlays I want and I will have basic stand alone instruments beside, in case it craps out.

3....The Pilothouse will have a PC Display w/ MAXSEA software to feed cockpit MFD or again be Standalone.

The new TZTouch2 has some really interesting wireless features and upgraded software to wireless link with both Android and Apple for remote monitoring.
Also PC configuring to slave to... or control the TZTouch2

This link gets into possibilities and their Forum is committing to more interface... FURUNO NavNet TZtouch2

With Rebate, it can be bought for $3,750

The Furuno Radar Radome options are a bit confusing as they market as DRS4D 24" Radome(4kw) and DRS4DL 19" Radome(4kw), and 19"DRS2 (2kw)

....The new DRS4DL does not need a PSU for TZTouch2
19" RADOME RADAR SENSOR DRS4DL | Marine Radar | Products | FURUNO

...The DRS4 Does!
24" RADOME RADAR SENSOR DRS4D | Marine Radar | Products | FURUNO

Given that with AIS, Radar is now probably more useful for "close quarter discrimination"...unsure if the DRS4 or DRS4DL is the better choice?

Perhaps some of you radar gurus can chime in

BTW...I look at the Furuno International website rather than the US one for better clarity.

Here is my solution for Cockpit and Pilothouse, very open to any comments and advice.

Season's Best!

Keep in mind that the DRS4DL does not support ARPA, so if you want that feature then you need either the DRS4D or the DRS2D.

[Pelagic]

Thanks....I missed that DRS4D it is

[colemj]

Isn't ARPA done in the MFD? Does the radome really do all of that computing and tracking? If so, how? Or radome has no connection to our instrumentation other than the MFD.

If it is done in the MFD, then the distinction seems artificial.

I honestly don't know what's done where. This has been debated a lot re Simrad. There is one guy who seems to have a LOT of inside knowledge who claims it's done in the scanner. But someone else instrumented the ethernet link and saw no traffic other than echo returns when creating targets. So who knows. And with Furuno, who knows even more.

The DSR4DL is only wireless for tablet use. It can't be used with the MFD. You either have the 2kw 19" or the 4kw 24" when used with the MFD.

It's a good question, and I have no idea how it's actually architected on anybody's system, but from my perspective it does make sense to do ARPA in the sensor. I believe it takes a fair bit of processing horsepower to acquire and track those targets. Considering that there are many customers who will never even buy a radar sensor, that would be unused CPU HP and memory that only adds to the cost of the MFD. Putting the ARPA processing in the sensor puts that cost on those who will actually use it.

See DRSD4L

It is specifically for use with TzTouch and TzTouch2

You are thinking of the DRS4W

It is the wireless sensor for iDevices.

I do want ARPA for the many targets in Asia without AIS...
But where did you find that distinction that DRS4DL does not support ARPA?

Here in the data on the TzTouch2
Radar | Features | FURUNO NavNet TZtouch2

and in this thread on the Furuno forum: Furuno USA Community • View topic - drs4d vs drs4dl

pages 12 and 13 of the 2015 catalog give a bit more detail of other functions missing from the DRS4DL

It's hard to find. Here is a link to the TZ2 brochure and it lists the radar options in a table a couple of pages in. It shows ARPA support, among other things.

Thanks guys.......like Mark I had just ASSumed that the processing of microwave signal for ARPA was done in the MFD......

You really need to read the fine print at this is counterintuitive to me

CF comes thru again!

With your rig, you might be able to fit an open array radar. I would check that out if I were you.

and apparently the wind instruments keep dying... up the mast i go... friggen 10 days old. grrr
