now i need the cable and dome and anything else...is there software i need to download...is there a website to get pretty good prices...the 18" dome is about $900 at boaters world.
Get Quotes from all vendors....
you should not need and software downloads unless you looking for waypoint transfer ...
you will need a whole list of items
DSM300
GPS 125 antenna
Chip for your area
Transducer
Dome
Heading sensor
the list goes on and on .....lol
Congrats on getting that sweet deal for TeamProSports....
The heading sensor is required for Radar - Chart overlay & advanced features (MARPA). If you are just using it for basic radar, it's not necessary. If you travel offshore, I would suggest adding the GPS antenna for redundancy. It's a really nice display.
Yes, the C80 won't be a backup GPS until you add the antenna, Elusive is saying you will have two full systems by going this route. The heading sensor is not needed by any means, just improves things. I use radar overlay on my C120 all the time but don't have a heading sensor. If you are cruising fairly straight and not making tight turns the heading sensor won't do much. It only comes into play when making tight turns, but even then it only takes a couple of revolutions of the radar before the chart and radar line up again.

Radar overlay done properly shouldn't take alot of turns to catch up. The GPS update is too slow. It may not mean a great deal in the bay, but if you are going offshore, or anywhere that wind and current affect your COG then using GPS is wrong. Radar should line up with your bow not your drift.
Yes, your method works OK, but if your serious on the water you should strive for correct, not just OK.

Well I guess I was put in my place. And to think I thought I was serious What did we do before radar and gps?
Despite the obvious advice here that a heading sensor will give more accurate overlay than gps alone as I stated previously the Raymarine C & E Series systems do not need a heading sensor for overlay to work unlike some other systems that do.

I understand that. He knows that already. I just put whatelse he needs to make that system work. I meant for the gps antenna to feed his position only.For heading for the overlay I recommended to him the E12102 Raymarine heading sensor. You could also do the KVH Azimuth 1000 to save a couple of bucks. I did not mean to confuse anyone by that last post. I have seen some overlays that work ok with just gps for the feed but I always recommend the sensor to do it right.
That was my point, it pays to do it right the first time.
Sorry, if you or Jim thought I was "putting someone in their place" because I most certainly wasn't. You guys are a valuable help (and source) for many of the forum visitors.
I realize that the C & E series from RM allow you to do overlay without a sensor, but it is still wrong and could cause a probelm/error under certain circumstances.
I used to advise my customers to do it right and if you can't afford it, wait until you can.
But relying strictly on your GPS could cause a problem/error at certain times. Simply put, electronics should never be relied on 100%. All these little tools we add exist to make things easier. Doing it right in one person's opinion is not right in anothers. I'm sure there are plenty of people that laugh at my electronics setup while there are probably many others that will ooohh and aaahhh over it. In reality it is much more than I need considering I could do it safely with a compass, clock, chart and a spotlight (for at night). And it just so happens that my radar overlay works great to boot! Granted, I will not be drifting with the current in the ocean anytime soon, but if I ever did I could just switch the window setup on my c-series to go to a dedicated radar screen in which case the display does line up with the bow. If none of us had a budget then yes, we should have a heading sensor on every boat, in fact we should have a gps heading sensor like the JRC JLR-10 GPS Compass Heading Sensor if we were serious, but funds are not unlimited so we can all afford different levels of electronics. The C and e Series do a very good job without the heading sensor while underway which is when I use my radar, it works for me. I know it is accurate because when Navionics says there should be a buoy it is surrounded by a big purple splotch saying there is a buoy there. I have a lot of things higher on my priority list to buy with that $600, such as fuel

What did we do before radar and gps?
