Default Simrad Radar Dome vs Open

Simrad has a 4kw dome for $2000. The next upgrade is an open 6kw array for $4000. It goes from 48 miles to 64. Is it really worth an extra 2 k for this?

Not unless you want to find birds with it. You need at least 6kw to find birds well as a minimum. The range won't matter if you have it mounted on a 10 ish foot surface above the water either, the curvature of the earth limits the range. You would need to mount pretty high to achieve 48 or 64 miles of range.

You can find birds with a 4kw, but it's just not as proficient at it.

You also hae to consider the size and weight of an open array. Often overlooked.

So, Birdman you think the extra $2000 for a 6kW open is worth it rather than a 4kW dome?

These questions are very subjective - it all depends on what you want to use it for, it's not a simple yes or no answer. All of these is this better is that better, is this worth it is that worth it one liner questions are useless without more specifics such as boat size, primary use, what you want the radar to be able to do, what system you're hooking it up to, model #'s, etc. etc.

Why don't you go for a Broadband Radar instead?

As mentioned, it's a very subjective question. I currently have a 4kw 24" HD dome. I'm very happy with it, it does all of what I need to do. It was ALLOT cheaper ($4k more for array + $2k more for motor), and after rigging the rest of the boat, I was at the end of the line!

Over the last 4 years, there has been maybe 3 or 4 times I said "man, wish I had an open array right now". Those were times I was in really bad fog or on a very dark night, going though some very tight channels with crab pots..... An array would do a better job picking them out and giving me better target separation on some of them... Over a 4 year period, would that have made it worth it? Probably not.

If I were commercial, a charter, or a more serious fisherman, I would likely be sure to spend the extra cash on an open array. But for the average rec guy, I think it's really not needed.

I also do not like the whole Bird finding thing with radar. Do a search for Bird finding on here, you will find your better off spending the money on a good pair of stabilized binocs like the Nikon 14x40's then trying to use radar. But again, if I were doing it for a living, I'd opt for the radar as well.

So in summary for me if I had the beans to throw away, and had the room and weight wasn't a restriction on my hardtop, I would get an open array. But if any of those were a concern, I'd go for a 4kw HD dome. That's exactly what I did, and have been happy with my decision. The new HD domes are very good.

good luck!

If you have the cash for it, the array is excellent. I have the 6kw (package deal on the NSE's was Great when they weren't all that popular) array, and I would never go back to a dome.

The 4kw dome shouldn't even be a consideration. The choice is between the broadband and the open array. If you want to find birds and have long range capability, spring for the open array. Otherwise get the broadband.

I have both the 6kw open and 4g on my boat.
I use the broadband 99% of the time. It's so good in close quarters and in the fog can't be beat. A 4 kw open won't show that log 15 feet in front of your boat.
I use the open array when I'm trying to find the shrimp boats.
I have a 6 month old 3G radar I will let go for 1100.00

Its going on a 40 Ocean Express with a hardtop, no bridge. Used for recreational offshore fishing in the NE canyons from the Cape ,maybe 10-15 trips year. I really dont care whats 64 miles away...Ill see it when I get closer. But would like to pick up birds within 10 -15 miles or just out of visual range---whatever that is.....

Then your only option is a big powerful open array. 6kw is marginal at best. I think you're better off going for the broadband first and if you later decide using radar to find birds is worth the thousands of dollars it costs, add a 10kw+ system later. The broadband will still serve its main purpose of close range navigation--no money wasted.

To get 10-15 miles of spotting birds range will take way more than a 6kw 4' open array. You are looking at a minimum of 6' antenna - 8' would be better and 10kw minimum. Assuming our antenna will be about 13' off the water, you might get 15 nm of birding from a Simrad 10kw 6' open array unit.
I run a Garmin 6kw 4' HD open array, and pull in birds at about 6-8 nm.

my 2 cents is spring for the open array if the budget will allow it. When it is pitch dark and there are hazards floating around, you will wish you had it even if it is only one time. Any radar will pick up a cruise ship. What you want is something that will pick up a small panga with no lights, a buoy where the lights have failed (common in Mexico) and one that will track that freighter moving at 20 knots that may or may not intersect you.
Others see birds, I see fuzz.

If a 6Kw can barely find birds then maybe the Broadband 4G is the way to go---better clarity and safer up close
