Now I get why the lock guys want it off as we move up or down.

We looked at a Mainship and its radar was mounted the same way.

Got to love the common sense argument.

In a fog, I need precision within one mile. I could give a crap about a fuzzy blurb 10 miles away. That's lower on the immediate priority list. I'll bang that a little later than my one mile obstacle.

You would care about the fuzzy if you were trying to find tuna, not everyone uses the radar to avoid stuff, I use the radar on my fishing boat to find thunderheads in the summer (thus the long range) and birds.

Interesting point. So what range do you have now? I have an older 24NM Sitex. Might get a newer Garmin in time. Any upgrade on my current model would be a plus.

I've got the 24mile. I've figured out the thunderheads part real good but the birds I'm working on. We fish here in the North GOM and you can sure make a day better buy running around storms. My present boat doesn't have the range to make the bird part work. My older radar set up was nice, you could scroll the pointer to a "blip" and mark it. When you mark it you could get the lat and long and go to that spot. Great for "finding" wrecks and Private reefs.

Mine 24 too, software dated, mid-90s. Not shopping actively, but browsing for next year hopefully.

I was interested but at the Seattle boat show all the major bands had no plans for broad band. I was interested as abackup for shorter range and better detail

I like the detail that broadband offers, but also have an affinity to Garmin, and gradually will likely have a Garmin network going. Broadband detail is awfully attractive, but also anything improving my current mid-90s set up is a boost. Software, resolution, and processing power nowadays is pretty impressive.

While our Furuno NavNet radar has, IIRC, a 36 mile range, the reason I have to type IIRC before that statement is that we never use it at ranges more then 6 miles. And most of the time it is on 3 or less. In the islands, it is often on 0.5 or even 0.25 miles (it will go down to 0.125 and we've used it at that on a few occasions in the fog).

Range can be important on the ocean or in large open bodies of water like the Strait of Georgia or the Juan de Fuca Strait. But in our waters, not only is the range limited anyway by all the islands but the stuff we're really interested in seeing is generally quite close to us---- crab pot floats, small fishing boats, etc.

Broadband could be a real benefit in this area where these kinds of short ranges are what's important. As we already have the Furuno and it's relatively new we have no reason or inclination to change it. But were we starting from scratch we would definitely check out what the broadband sets had to offer.

Range: When we scan at night we usually only go out to 12 miles and then step down to 3 miles. The Simrad Broadband 4G Radar advertised range is 36 miles. Talking to people in the industry, they say functionally to 32-34 miles. That works for us!

Also, there is no magnetron in the HD/broadband radars, so no exposure issues plus instant on and low amp usage.

Our Furuno 1931 is on it's last legs so this is a timely discussion.

Is the close-in resolution everything that you hoped/expected it to be? Any screen shots you can share?

Not sure if there's a way to plug through some kind of NMEA 2000 interface and have it show up on my Garmin 740s screen I suppose

Ben, I think it highly likely that it would be NMEA 2000 compliant, and therefore probably able to link with your current display. However, even if not, can you see a company like Garmin being left behind in the tech race. Mark my words, they will have broadband version out before long.

On my last boat I had a Simrad radar/gps setup. I liked having the ability to split the MFD screen to show a short range (1-3 miles) and a long range (24-32 miles) at the same time. The long range was nice when trying to pick up land forms and the short range obviously for avoiding unpleasant encounters.

As to tipping the radar down using a shim when mounting it, as one who cruises a bit faster, I like having the radar beam aligned with the surface of the sea rather than shooting up into the sky neuterizing passing sea gulls.

Ben: We haven't replaced the Furuno yet but everyone we have talked to and what we have read seems that the Simrad 4G Broadband would be a good fit for us. We don't use the long ranges and if we did 24 or 30 miles would be more than adequate.

The close up resolution is suppose to be one of the strong points.

It is NEMA 2000 compliant but I have no idea if you can interface it with a Garmin system. Simrad is good about emails. If you find out, let us know.

Hi Larry - ok I thought you already had the 4G. I'm in no urgent hurry. I've got a good old Sitex unit now that works. My need is more close-in safety than long range weather or bird flock-detection for fishing. So a year ahead of a potential purchase, the broadband resolution difference is very compelling.

If I take the easy route with my Garmin, I can buy an 18HD radar from them for around a grand and plug straight into the back of my 740s.

But currently my route to broadband is likely buying a NMEA router to plug all components into, at some extra cost.

Again, not there yet, just thinking ahead.

This is a great discussion on radar.. I'd like to see the same on chart plotters.

Ya, I was looking at larger or smaller screens and thought to go with a Garmin 4208 for screen size, but the 740s was slightly more modern.

Plus, I got a deal since the owner was selling his new unit on Craigslist. He bought his, but as he partnered his boat with a friend, and friends girlfriend bought his, he had to sell. So I got a boxed unit with transducer for like 25% off. Made the purchase easy. Works like a charm.

Only down side is touchscreen loves my fingerprints. So if you're a messy eater like I am, think twice about touch screen. (Actually, I made all the prints early, testing and playing, so maybe better in regular use.)

The sonar data and graphics are outstanding. Beats the detail of the GPS part. I just need to finish transducer install.

Here are a couple of 4G screen shots. I don't have a heading compass hooked in, so I can't do overlays. One of the most annoying "features" of the Simrad is that I can't lock the scales of non-overlayed displays. In fact the scale settings usually don't match, as you can see here, one is 0.1 nm, the other is 1/4.

The other interesting thing about resolution. I can often see the wake of boats (including my own). It took me a while to figure out why I was seeing two or three hits on boats 1/2 mile away.

As you can see from the marina plot, the close in range is amazing. If you look, you can even see the walkway down the center of my dock (covered).

Bob that's pretty impressive. Thanks for the shots. I can only imagine in the slip there's a lot to bounce off of. Good pic that one. The channel shot is real crisp too.
