Holy Garmin cow: SideVü/DownVü, GPSMAP 800/1000, GMR 18/24 xHD, Meteor 300, gWind & the Helm app

... written for Panbo by Ben Ellison and posted on Nov 18, 2013

Garmin_SideVü_DownVü_800_kHz.jpgGarmin is purportedly announcing nearly fifty 2014 marine products today!  A lot are related to the company's new ability to offer the high resolution down and side scanning that's become so popular with freshwater and near coastal fishermen (and curious gunkholers like myself). Soon the relatively easy-to-understand (and fit-on-a-small-screen) down view will be available in new echo dv fishfinders and echoMAP dv fishfinder/GPS combos that will then better compete against similar products from Lowrance, Humminbird and Raymarine. Moving up the cost curve you'll find CHIRP-assisted DownVü and SideVü, which look wicked sharp in the screenshot above (imaging what's likely the remains of a bridge in a man-made lake)...

Garmin GCV-10 downscan sidescan new 11-13.jpgCHIRP assisted SideVü and DownVü originate in the GCV 10 black box above, which is obviously networkable. In fact, the GCV 10 probably explains, at least in part, why Garmin put a second Ethernet port on last year's new GPSmap 741 Series (Panbo discussion here). Garmin's fully networkable systems -- like the 6-, 7- and 8000 Series -- are not yet listed as compatible, but it certainly seems possible (and desirable). I haven't yet found photographs of the 12-pin 455/800 kHz DownVü/SideVü transducer that comes with the GCV 10 or the 8-pin "all-in-one" 77/200 kHz sonar/DownVü transducer that comes with the various new echo dv fishfinders, but I imagine they are half-tube shaped and will come as transom mounts with thru-hull options later (as all the down and side view manufacturers have done). 

Garmin_GPSmap_1040xs_new_11-13.jpgHD-ID sonar/DownVü is also a built-in choice for the new GPSMAP 1040sx and 840sx, though they can also support traditional 1 kW sonar and CHIRP. These are non-touch displays with an 8-softkey and dedicated button interface quite similar looking to the 6000 Series.  Both models come loaded with both LakeVü HD maps and BlueChart g2 coastal charts and can handle both BlueChart g2 Vision and the new LakeVü HD Ultra regional cartography packages. Meanwhile, the new GPSMAP 1020 annd 820 lack the built-in fishfinding and charts but offer "Special Sailing Features," including "laylines, enhanced wind rose, heading and course-over-ground lines, and true wind data fields" (no screenshots yet; please holler if you see some).
   All these new MFDs offer "select networking capabilities that allow you to share features with other compatible GPSMAP units, such as radar {all models}, GCV 10 DownVü and SideVü scanning sonar, supplemental maps, and user data, such as waypoints, routes and tracks." In other words, I think, Garmin is sticking with its strategy of limiting the network abilities of less expensive MFDs like the popular 700 Series, but a lot less so :-)

Garmin_GMR24_xHD_new_11-13.jpgGarmin also has new GMR 18 and 24 xHD radomes, both of which are 4 kW with purported 48-mile maximum range. Both are also dual speed with automatic control, can work at dual ranges simultaneously and feature dynamic gain and sea filtering, all rendered on screen in "vibrant 8-bit color for greater detail of weather patterns or obstructions." I think that this is an important update for Garmin as their radomes (not their xHD open array radars) seemed weak in the comparative HD radome testing I did a few years ago. Hopefully, next season I'll get to see if they meet or even exceed the competition (and whether they'll network across fully and selectively networkable Garmin MFDs, which seems like a "maybe" at this point).

Garmin_Meteor_300_new_11-13.jpgAnd how about Garmin Meteor 300 black box audio system that's sort of like Navico's SonicHub, but based on newer Fusion technology? So, it has Bluetooth streaming and control, and it can be accessorized with a NMEA 2000 remote and/or an Apple-connector-change-safe and Android-friendly dock (note that Lowrance and Simrad have also added SonicHub support for the Uni-Dock). Many GPSMAP models will porportedly be compatible with the Meteor 300 over N2K, and if that interface is like what I'm seeing with Fusion-Link on a Garmin 7212, which is very likely, it will be a fantastic way to run your stereo when you're at the helm.

Garmin_gWind_n_GND_10_Nexus_interface_new_11-13.jpgAlmost finally, the relationship between Garmin and their sailing instrument developer, Nexus Marine, has taken an interesting turn. The new gWind sensors, both wired and wireless, at least look exactly like the unique Nexus design I first saw at METS in 2006, which is just fine because it's earned a good reputation and, even better, Garmin's version comes with a GND 10 Black Box Bridge that apparently integrates Garmin's NMEA 2000 data system with the 0183-based Nexus Network. The box, which is available separately, even supports PC applications like NexusRace and Expedition, and is apt to make some sailors with existing Nexus systems very happy (and more likely to be Garmin customers if they aren't already).
   Finally, I think, there's the new free Garmin Helm app, which is not really a surprise. I don't have screenshots yet, but how nice that it became available on the Apple App Store today. So far, only Garmin's GPSMAP 8000 series is compatible -- and you'll need a WiFi Adapter Kit (which I still think will be replaced eventually with a better Garmin-built model) --  but it seems safe to presume that smartphone and tablet mirrorings and control will come to other Garmin MFDs in due time.
   I'm sure I've missed many details of all these new products, but hopefully, people visiting METS (like Kees), or those otherwise in the know, will fill in.

Comments

Doh!...already finding details I missed, though partly Garmin's fault. For instance, the new GPSMap 800 and 1000 Series all specify "Garmin Helm support: yes" so the new app is already slated to support more than the 8000 series.

The same MFDs also specify "Wireless connectivity: yes" which may mean they have built-in WiFi (and/or ANT and/or Bluetooth)?

The Raymarine CHIRP down scan did not seems to provide any resolution boost compared to Humminbird and Lowrance. I think at this time the resolution from the narrow beam width and high frequency are about all that can be taken advantage of. I would love to be proven wrong though!

Posted by: Stiletto at November 18, 2013 2:06 PM | Reply

Stiletto, I think the Ray unit is somewhat better than the others, but more importantly you can typically use it at higher speeds, and in deeper water. Getting a transom mount transducer in the right place is critical to its performance. Time will tell with the new Garmin tech, but their history says they wouldn't have taken it to the market if they didn't believe it was much better than the existing technology.

This is awesome. I have been waiting for a decent non touch replacement for my 3206s. That 820 might just fit the bill. It would also bring my system up to all NMEA2000 except for my AIS transponder.

Bill,
With LSS2 I get bottom images at WOT. I get little or no bottom detail above about 15mph, but I doubt the Raymarine does much at that speed either. That gets into ping rate and doing it fast enough that you haven't moved on too far between each ping. Plus, at depth, I haven't seen any images from anyone that shows any level of detail worth seeing. I would like to see pictures that show otherwise :)

Hey Bill

Question re: the new wind sensor.

- directly outputs n2k?
- what's the mount look like. Easily detached for storage?

Thanks

Paul, looking at the gWind specs, particularly what's "In The Box", is revealing. The wired version comes with a 25m cable with a female Nexus connection and there's also a field attachable Nexus connection. (And the wireless version comes with a Nexus wireless box that connects to the GND 10.)

There's no detail on the bracket but it seems quite possible that the sensor will be removable since there's a connector up there.

There's almost no doubt that the data coming down the mast is in Nexus format, and that the N2K conversion happens in the included GND 10. Maybe a dite complex but you end up with the data in both formats, which could be useful.

Was at METS and can tell the following
In answer of the first comment , Al new plotters and echo-MAP'S are equipped with WIFI the helm APP works with all of these plotters, view and control according to the new catalog.
Sailing features include lay lines showing them as easily as making a way point the Garmin way, the have a new wind rose displays true AND app wind angle.
The new Gwind is mounted in a mast bracket therefore easily removable from the mast-top same way as the Nexus wind transducer. the Garmin people who saw the new radar at work could tell me that they where surprised of the echo's no more/less side-lobes and echo's of small bouys up close and further away also branches of under water trees sticking above the waterline, last wash told by the people who sell the stuff , now it's up to Ben to confirm it.

Thanks, TCY!

This morning Garmin is announcing a software update that will make DownVu/SideVu accessible from existing Echo and GPSMap 700xs devices, along with some other features they haven't had before: http://goo.gl/TCAZue

It also sounds like the sailing features will get added to some existing MFDs but once the dust settles I think Garmin needs to built a matrix showing what works with what.

Posted by: Ben at November 21, 2013 7:59 AM | Reply

Paul, I only have half of the wind system, I'm waiting for the GND 10 to show up. The Nexus, and Gwind mounts appear to be identical, and a simple twisting of a plastic locking nut removes the unit from the mast. The GND 10 does output N2K. The USB cord/plug is a PC interface. I believe one of the two center plugs is for a pigtail cable from the NMEA 0183 outputs on the WSI wireless box, but I suspect Ben's thoughts are correct about the other. There is virtually no difference, if any at all between the Nexus wind instrument and the Garmin version.

Posted by: Bill Bishop in reply to Paul at November 21, 2013 8:44 AM | Reply

I think what Nexus uses is an 'improved' version of NMEA 0183, sort of like SeaTalk. You can see the Nexus nWind bracket and more in the manual:

http://www.nexusmarine.se/support/transducers/

Also it occurs to me that as much as I love NMEA 2000, it's a bit of a problem for wind ducers on tall masts. The backbone has to go up there, as well a terminator. Using Nexus for the mast run might be a bonus, then, plus I think the cable is thinner than any N2K equivalent (except maybe SimNet).

Posted by: Ben at November 21, 2013 9:51 AM | Reply

Correct me if I'm wrong, but the Gwind is actually the NWind + GND10 being both in 1 box. they use the nexus signal up to the GND10 both inner plugs are for the Nexus signal 1 for the wind transducer the other going to Nexus displays.

Posted by: TCY at November 21, 2013 1:43 PM | Reply

You got it, TCY! In fact, if you're a Nexus owner with a broken wind whirly, you can just swap out the masthead unit, plug the old cables into the GND 10 box and you're good to go (with added N2K display options).

But I was wrong to say that Nexus uses modified NMEA 0183. I just spoke with a well-informed Garmin/Nexus source and learned that the latter built their own FDX data language that's purportedly quite able and fast.

Actually, the larger purpose of the GND 10 bridge is to support customers who may well be happy to keep Nexus gear that goes back decades. Garmin isn't really pushing the bridge aspect yet because they have more work to do translating Nexus functions into NMEA 2000 for use on Garmin displays, but that's the road map.

There are other interesting attributes to the GND 10. You can, for instance, put the gWind on a NMEA 2000 network with no other Garmin (or Nexus) gear on it and calibrate it using a laptop and free Nexus Race software. That applies to gWind Race too, which is more expensive largely because it supports sophisticated calibration tables. All the calibration lives in a gWind, so what goes out over N2K is corrected.

That same Race software also supports data monitoring and logging and it has a virtual NMEA 0183 port that can pass info to other sailing or charting software running on the PC. Which can include some info like GPS that's bridged from NMEA 2000 to Nexus FD in the GND 10. Apparently Garmin now has some of it engineers (sailors!) working with the Nexus team in Sweden, and it sounds like they're up to good things.

Posted by: Ben in reply to TCY at November 21, 2013 4:03 PM | Reply

Ben don't know for sure if the swapping is going to work you need some kind of adapter cable.
The new sensor I saw with Garmin stamp t on it does have a new/different plug. the nexus has 4 pins and the new Garmin (as far as I can remember) has 6. It looked just like the ECU CCU cable plug.

Posted by: TCY at November 24, 2013 8:17 AM | Reply

TCY, it was the Garmion Nexus expert who told me that the gWind and nWind masthead hardware are interchangeable. Also note that Garmin lists the gWind masthead cable as using Nexus connectors and that a plug with six female holes does not necessarily mean that the male side has six pins. Click on the GND 10 image above and you'll see what I mean. The Nexus ports appear to use 4 pins but have room for 6.

Posted by: Ben in reply to TCY at November 24, 2013 9:10 AM | Reply

Sorry, TCY, I confused what Garmin told me. The gWind and nWind brackets are the same, but the cable is not. "The gWind transducer has a 6 pin Garmin (looks like device net but doesn’t use all the connectors only 4 pins) plug for attaching to the gWind 6 pin mast cable" but there is a short adapter cable for Nexus owners who want to replace an nWind.

Here are the install options for both Garmin and Nexus users:

"So if you are replacing a Garmin GWS10 you would change the mounting to the now removable gWind bracket. You would then need to run the new gWind mast cable. The good news here is the new mast cable is smaller (4.3 mm) than the n2k cable that would be currently in the mast. At the base of the mast you would then use a field installable connector (010-12117-01) to get to the GND10 Nexus network port. This connector comes in the box when you buy the whole gWind kit. Then the GND 10 would be connected to the Nexus network and NMEA 2000.

If you have a Nexus system and needed to replace the masthead for some reason and have a good mast cable and bracket here is the thinking.

You would attached the new gWind transducer to the existing bracket. Then use a gWind to nWind mast cable adapter (part number 010-12117-02, $25 list price) which will be a Garmin 6 pin plug on one end to go to the gWind and then a female Cannon plug on the other end for connecting to the existing Nexus mast cable. At the base of the mast you could do one of two things.

1.Move the mast cable to the Nexus network (assuming you didn’t already have a nWind before which would have already been connected to the Nexus network). Then connect the GND10 to the Nexus network which will then send data to NMEA2000.
OR
2.Get the field installable connector and plug the existing Nexus mast cable into the GND10 then the GND10 to both the Nexus Network and NMEA 2000 so that the GND10 will provide wind data to both the NMEA 2000 network and Nexus Network."

Garmin issued lots of software updates last week. Things I notice are wide support for the new xHD radomes, support for Fusion Bluetooth streaming, and support for a new GXM 52 weather antenna: http://goo.gl/pl3Aqd

The GXM52 doesn't seem to do anything the GXM 51 can't except maybe "Additional features and upgrades will be made available as Sirius XM capabilities are added." Anyone know what that means?

My husband and I both work for a competitive.. and "well known" marine electronics manufacturer.
Suffice to say that this new line that Garmin is bringing out is attracting great interest from many of our colleagues.
It's gong to be a very interesting Miami Boat Show.

This winter, 2014, I’m installing an 18” monitor at the Nav station which puts a squeeze on space. A black box, Bluetooth AM/FM would be the answer for me. Here are some thoughts as I considered a new AM/FM radio.
Since most sailboats have very little space for electronics I think the Meteor 300 may have wide appeal.

AM/FM: 
I’ve been using a non-Marine Sony car radio for many seasons that has terrific fidelity for a one zone, two speaker system. The standard DIN size chassis requires a lot of room to the rear and restricts where it can be installed. In my opinion, any new radio considered as a replacement must have built in Bluetooth as well as a standard 3.5mm plug. I looked closely at the Fusion radio's and read the rave reviews, but honestly, I disagree with the Fusion design. How could the Fusion engineers make a radio without built in Bluetooth, (an add-on Bluetooth device is a band-aid to an oversight). With Apple changing the plug every year the Fusion tray is obsolete in short order. Trying to accommodate one brand of cellphone or iPod is a mistake. So, the new Meteor 300 seems to fill these objections.

The Garmin Meteor 300 has Bluetooth built in, the black box configuration allows many possible installation options away from the crowded nav station. The auxiliary remote, sold as an option, can be moved from place to place and my 7212 can control the Meteor 300 via N2K. What a terrific combination of features.

Now, does it have the sound fidelity the average person can appreciate?

Posted by: Richard C at January 3, 2014 1:59 PM | Reply

Richard, I agree that the Meteor 300 looks good but please understand that it's built by Fusion and probably more like existing Fusion gear than you may realize.

For instance, there's nothing I can see on the Garmin site that says that Bluetooth is actually built into the 300 box. In fact, "Bluetooth wireless technology for music streaming and control" could mean a Fusion BT200 hung off a plug on the 300 box. But you might be glad it is because then you'll have a chance to position the BT antenna a few feet away from the radio and the other stuff it will probably be mounted near.

According to Fusion the main reason they were 'slow' to adopt Bluetooth is that they think it's hard to get good fidelity and reliability on a boat with. Quite a different EMI and device distance scene than a car. At any rate, if the Meteor does have its Bluetooth all inside the black box, I'd say Fusion now thinks it works OK that way and will probably do the same in future radios under their own brand.

The Meteor dock looks to be the new Fusion Uni-Dock which can handle most any cable changes. Fusion did get caught flat footed when Apple suddenly went from the 30 pin to Lightning connector but it only happened once and I really doubt they or any accessory manufacturer is going to make that mistake again.

I tried the Fusion BT200 briefly and it seemed to work well but at that point I had to choose between it and the Garmin 7212 FusionLink interface, which is fantastic. A recent Garmin update made it possible to have both with Fusion 700 systems and I intend to try that in the shop, as well as FusionLink with Furuno, Raymarine & Simrad.

The Meteor N2K remote seems to be exactly the same as the Fusion NX200 or 200i and Meteor must have stuck with Fusion's proprietary N2K connector because the remote and 300 each come with an adapter cable.

PS. Richard, If I were in your shoes I might also be looking at the Fusion RA-205. It's very compact, has N2K, FusionLink, and can work with either of Fusion's BlueTooth devices. I think it might end up less expensive, you'd have a stereo even with N2K turned off and phone dead and -- a big thing for me -- you'd always have a big volume knob and mute button.

You could be forgiven for saying that Garmins DownVu and SideVu seems suspiciously similar to Navico's Downscan and Sidescan technology.

And you'd be right.

Garmin 'acquired' almost all of the senior sonar engineering team from Navico's Tulsa R&D center by setting up an R&D center of their own very close to Tulsa in early 2013 and then head-hunting Navico staff by offering them well-above industry standard salaries with added incentive of not requiring them to relocate away from Tulsa.

Navico sue'd both Garmin and the engineers concerned over this:
http://www.oscn.net/applications/oscn/GetCaseInformation.asp?submitted=true&viewtype=caseGeneral&casemasterID=2507447&db=Tulsa

Navico did not win this case which only serves to say that Garmin did not act illegally.

What this does say about Garmin is: when you can't win - play dirty. It amounts to marginally legal IP theft.

Booooooooooo to Garmin

and to the sellout engineers involved. Most of whom had been employees at Lowrance/Navico for over 10years.

Ben, your readers have a right to know about this.

Hello Anonymous,

I understand what you are saying here but can you blame the engineers for taking the better offer? After all, I’m sure they have families to feed, with mortgage and music lesson to pay for, college, etc… The engineers loyalty is at home not Navico. To be overly fair they should have given Navico an opportunity to match the Garmin offer, but had no obligation to do so. Protecting the intellectual property is the job of lawyers - maybe they are the ones at fault.

My successful friends in business tell me they carry two documents with them at all times. One is an unsigned letter of resignation and the other is an up to date resumé. They review opportunities for advancement every six months in order to maximize their career. After watching them for a few decades they are now wildly successful.

Ben,

I took some time to again look over the Garmin Meteor 300 and Fusion radios. The Meteor 300 web site is still half baked with little information posted. The concept is terrific, but how does one make a buying decision without looking over a manual (none available yet). I did see in the FAQ’s that the file format the Meteor can use are limited to only three and AAC is not one of them. All my iTunes music files are AAC. I suppose its not a big deal as they can be converted to MP4 - I think.

The Fusion RA-205 is a fine possibility for my application. However, I’m going to hold off until spring and see if Fusion comes out with their version of the Meteor 300 along with some polish on the specifications. If not, I'll go with the RA-205.

Please Fusion….. fix the chaotic drop cable mess. We all know about NMEA 2000 and can screw a cable into the network - we don’t want to mix and match adapters….. Never, never build to Apple or anyone else’s plug. Apple just changed the charging dock on their 13” Retina Macbook Pro to a connector that matches no other Apple product. Apple will burn you again with the iPod, iPhone connectors….. Learn how to build in Bluetooth. Everything I own has Bluetooth built in - my boat computer, laptop, iPad, iPhone, mouse, keyboard and my crew all have devices with Bluetooth built in. We have been using Bluetooth aboard the boat for a long time now without a single conflict or drop out….And, personally, a black box AM/FM like the Meteor 300 opens the door to many installation possibilities and I believe may have wide appeal.

Posted by: Richard C at January 5, 2014 9:11 AM | Reply

Richard, I too wish that Garmin was quicker at posting manuals and also more complete with their specs. For instance, I'm not sure that the Meteor won't play AAC files off an Apple device just because it can't play them off a USB stick.

If Garmin demonstrates a Meteor 300 at the Miami Show in February, I'll try to be there, and maybe they'll send one for testing.

I must say I don't get your attitude toward built-in BlueTooth. Once you've plugged a BT100 or 200 into a Fusion system, how will you or anyone else on the boat know that it's not built in? More important, I think, is how well the software works and I know Fusion has been working hard to get the maximum utility possible from Android and Apple BT audio.

Also, I doubt that Fusion will change its NMEA 2000 connector strategy yet again. They seem intent on the idea of providing a lower cost and self-powered cabling system for remotes on boats that don't have a standard N2K network. It is messy for those with regular N2K but again once you have the right adapter cables how will you know the difference?

sharing Maps radar etc. whit a marine network ?? the standalone GPSMAP 721 is now a MFD. indeed wow.
Mounted my first GMR18XHD today looks great. it has 8 mounting holes so there is a possibility to mount the radome further or closer to a mast and what is nice cabling is the same as the GMR18HD, Garmin placed a status led underneath the dome ,so visually can be checked what the radar is doing (or not). it came with new software after loading it the radar appeared in the start screen of an GPSMAP 8008. can't tell how good or bad the image is because the boat is inside.

I fish offshore in 40 to 120 feet of water on a 23' boat and am replacing my electronics. I want a GPS/sonar combo in the 9-11" width x 7-8" height range (i.e.- 8" or 9" screen) such as the Garmin 840xs or Lowrance HDS-9 Gen2 Touch. Three questions:

1) Does the down scan imaging work well at depths of 40-120 feet?

2) Is there any reason to get side scanning capability given the depths at which I fish?

3) Is one brand significantly better than the others or are they all pretty much the same?

Vince, I think the value of down scanning declines after 40 feet, and side scanning even more, but they'll still be working, possibly all the way to 120 feet. I have sometimes seen rocky Maine outcrops over 100 feet deep with just the original StructureScan black box and transducer.

In many cases the side scanning almost comes free with the down scanning and is certainly worth it, I think. But which one is best is a tough question. Lowrance seems to have earned the lead among fishermen like you but Garmin is now focusing their considerable resources on the same market, and you really ought to check out Humminbird too. The new Onix 8 seems aimed right at your needs: http://goo.gl/hKXwHB Plus I think Raymarine's CHIRP DownVision might work well for you, though Ray doesn't yet have side scanning.

But a lot my experience with this stuff is demos only and I'm not much of a fisherman. I highly encourage you to pose the same question on The Hull Truth (and I like to see the answers myself):

Also, look for an announcement from Lowrance tomorrow that might be relevant to you. I'll have it here.

Vince, I agree with Ben's assessment, and would add that both down and side scan work best at very slow speeds. I would suggest that down/side scan systems when used in conjunction with standard/CHIRP sonar system will provide the best opportunity to locate fish. I'm installing my first Garmin down/side scan system tomorrow and will post my sense about its capabilities.
