Default Raymarine C-80 x 2

Had a C-120 and now due to new boat I purchased having less helm space I am thinking about installing two C-80's side by side and using one as a chartplotter/radar and the other as a fishfinder/data display. Does anyone else use this combination or a similar combination? Suggestions and/or comments welcomed. Also, using chart overlay for the first time and would like some input from people who have used it.

If you can swing the extra $ I would reccomend the E series. It would give you more flexability and features. If not then the C series could be used as described in your post. Either way you will have a great setup.

I would like to do that because you could have a back up if one went out,BUT 2 c-80's are larger than 1 c-120 nad take up more space.

You may want to consider the E series. Then you can switch functions between the screens. If this is not important to you, just decide which unit you want to be your radar, and which unit you want to be your fishfinder. This will help you select which unit will be on the right and which unit on the left. I would definately get two GP125 antennas so that both units can be used as chartplotters and you have the redundancy. This is what my buddy did. What kind of boat do you have?

I have a C120 and C80 on my boat. I connected the RS125 GPS antenna to the C80 and then to the C120 via the Seatalk (red wire of the RS125). Both units have separate Navionics chart chips and both are GPS/Chartplotters, no need to run two antenna's. It is my understanding that the RS125 is the GPS, not the units, and it sends the GPS signals to both units. Both units act independant of each other. I also connected an autopilot to the C120 and it sends the magnetic heading from the C120 to the C80 via the same (Seatalk) red wire from the RS125. On my boat the C120 is the radar, GPS/Chartplotter (on console) and the C80 is a GPS/Chartplotter, sonar (in the electronics box above).

The RS 125 is not the expensive part. The head unit is. By having two seperate antennas you have two seperate units. Redundancy. It is nice to have a back up.

Like the idea about the two antennas. I'm getting a 2007 Robalo 240CC with twin 150 yamaha outboards.

I have an almost identical system (twin C80s) and unless you need video or weather you don't need the E series IMO. Spend $300 forand extra gold chip and $150 for a NMEA multiplexor instead of $3000+ for the E series upgrade on both units. With the Seatalk junction box ($20) one antenna feeds both units regardless if one or both units are on. You may be able to get away without the multiplexor but I have Smartcraft, autopilot w/ 2 in and 1 out plus VHF in/out. Figured why not, it helps keep everything straight... Take the money you save and buy an alphanumeric keypad, fishing tackleAND jewelry for the wife/girlfriend.

Still not fluent with the overlay. I've used it but mostly to see how the chart lines up with real time radar images like channel markers, breakwalls, etc.and to see how a storm may be lined up with the inlet. The overlay is a nice feature I just haven't spent enough time messing with it to put a value on it. Radar in general though is great to have... I've had this setup for about a year and have no complaints whatsoever.

The RS125 is the GPS, not the C Series unit. When you GOTO a waypoint on one C80 the other C80 mirrors this without having to plug it it. When cruising to a waypoint I usually have the right C80 with chartplotter and the left with the waypoint data enlarged for easy reading. Depth data is passed between the units also but no picture. Just the depth.

And what happens IF your RS125 fails?

I almost went the route you are talking about but just bit the bullet and got 2 E series. I love the Raymarine technology...you'll be happy with the setup.

Jim31, The reason I went with one RS125 is I have limited room on my arch, and really did not feel the need to have two separate gps antenna's. My research did not reveal that these antenna's had failure issues, infact they are extremely reliable. I have a hand held back up, plus I have a Raymarine A65 (gps/chartplotter/sonar) with separate antenna in the cutty cabin. The reason for this extra unit in the cutty is I wanted to be able to hear the anchor alarm should it go off, I might not hear it in the cutty when it goes off at the console. For my purposes, this set up is just right. It definitely does everything and then some. I did not want to pay the difference for the E series as I did not have a need for the video card or camera and no need to watch tv/dvd on the screens (as I have a 15" lcd flatscreen tv/dvd in the cutty). I agree with you that having duplication is a good thing. Taking the money saved (from buying the E series) and buying something for the wife is priceless!

Thanks mtcfish. I have the TR-1 autopilot -the black rectangle left of the sounder is the controller and all the other equipment is mounted out of the way. Never found a use for a display on an autopilot, the chartplotter does that for me...

Jim Z - Great looking install Mfgs have finally started thinking about the ergonomics of the console - space and angle. I've been thinking of adding one of these to get SeaTalk data at a glance




Seanile - Looks like you have room for 2 E80's ! 1 for cockpit camera and 1 for Sat TV Also a great looking install

As for the twin GPS antennas although failure is remote, IMO the best setup for reduncancy would be 2 antennas. Power for the antennas would be controlled by a SPDT switch allowing either one or the other to be on, thus "saving" one as a backup

Seatalk is a beautiful thing. Plug and play!

Elusive, I agree with adding a Tridata. I like to see the speed, temp., and depth all in one large easy to read location. This way you do not loose room on the main unit. People argue the screen is so big, why worry, well I like the larger view of the Tridata.

I'm getting ready to purchase 2 e80's and 1 e120. Have any of you had any problems with your e series machines? The E120 is going in a tower and will be exposed to everything. How would you judge you fishfinder? Any feed back would be helpful. Thanks

Jim,

I also have a hard time justifying the $3,000 difference for the twin E 120, vs C-120. The platinum chips are kind of gimmicky, and I don't plan on watching DVDs from the helm. I stopped by the Raymarine booth at the NE Boat Show, and the rep told me that the Sirius weather would be available for the C series in April. You can get the GPS redundancy a lot cheaper than relying on the E-series network capability.

The only other reason I could see for buying the E series is the screen brightness. Do you find that the C series is bright enough for use in sunlight?

Thanks,

Joe
