Any of the current round of garmin radars will work with it. You should probably focus on the 18 or 24 hd, and probably the 24hd.

The non-hd's are barely adequate (in the domes). You probably don't need an open array.

Thank you for the reply. I am new to radar and dont know much about it. Should I buy new or used? does it matter, are the units pretty reliable ? are there any used ones out there?

You can find them used, but for someone new to radar I'd recommend new, and have someone who knows the system install it and set it up. It's pretty easy, but there are a few things that will make it more reliable in the long run.

New will get you a warranty. New won't be getting you a potentially buggy unit that mostly works but sometimes doesn't.

The main issue people have had (outside of early death) is the units will sometimes plague you with a "Radar Service Lost" error. These can be installation related, or just internal errors.

Otherwise they work ok. It's not commercial grade but you aren't paying for that.

Well, Here is the next question ,,,,, Is my 3210 even worth putting one on? or is that an old outdated unit that should sold and updated ??

If it is still in good working order than you can add a new radar.
Those were very reliable units.
I agree with Gerg..a new radar is best...a GMR18 will work nicely.

I would say yes. If need be, you can always upgrade the 3210 later.

the 3210 is still a pretty good unit, imho. I really like mine.

Of course, there are newer, better units out there, but like buying a computer or laptop, there always will be..

Thanks for the replys. I just need to find out all that is needed to add a 24 hd dome

i just added a radar a few weeks ago.

I'm assuming you have something else on your boat hooked up to the 3210? maybe a sounder (gsd 20/21/22)?

If so, if you don't already have a GMS10, you'll need one of those. It's basically just a hub. You plug your 3210 into the GMS10, and then any network peripheral you have also goes into the GMS10.

Once you have a network, then you can focus on the radar itself. Most people would recommend you get a stand for the radar to raise it up a bit. You'll want to raise it for a couple of reasons, primarily:

1) To lift it above any gps or xm antennas (you dont want them on the same plane)

2) To make the radar a little more effective, the higher the better, also, most stands usually have a bit of down tilt to them so that when your boat is running on plane, the radar is level to the water as opposed to pointing up at the sky.

You'll also probably want to get a stand that has an anchor light attachment to it since more than likely the radar will become the tallest point on the boat and you'll need to make the necessary modifications.

On my radar, there are only two connections to worry about. one is the red/black power cable, the other is the ethernet cable that plugs into the GMS10.

its really a simple install.. for me, the only real hard part was running cables through the top and into the console.

I have a 3206 with a 18HD dome. For a low cost radar unit it works very good. It also does radar overlay. I just use it for radar. The 6.5 inch screen is a little small, so on very foggy days I run it at 1 mile, but it will go out to 36 but you can't see much. Your 10 inch screen will be much better.

It sounds like an easy hook up. I will likely go with the 24 hd for a tighter beam width. I won't really need it for distance, (furthest I have ever gone from shore was 20 miles.)
Thanks everyone for your replies.

I have a Garmin 3010C with a GMR18 (not HD) radar mounted on the mast of my catamaran. It works for me, and the MARPA feature is great.

I suggest you play with http://www.furunousa.com/LearningCenter/Radar-Horizon-Calculator.aspx to see how high the antenna needs to be. If you can't mount it high enough to use the range of a GMR 24, you should step down to the 18HD.

I wanted to see shoreline and low islands as far out as possible, but I had to settle for displaying things that stand 6 feet above the water. With my 18 antenna 30' high I can see 10 miles, but at 7 knots that gives me a 1.5 hour warning. I can see barges at that distance, and pick out fish weirs at a mile, big bouys 10 miles away, and crab trap floats at a half mile in fairly calm water. The longest non terrain target I've spotted was a Coast Guard Helo at 1500' with an AIS signal at 28 miles. The AIS symbol and the radar return were in almost the same place on the screen, and MARPA tracked it! Amazing!

I looked. I do have a gms 10 box.

perfect. all you need is an ethernet cable running down into the gms10 and then somewhere to hook up a positive/negative cable... and a radar stand.. done deal.

this is what mine looked like mocked up on the stand i got with the light attachment.
