Default Garmin CMR 404 Radar- will it see birds?

I've been working on some specs for a new boat, and I like the Garmin network system. However, they don't make a 6 kw open array radar, only a 4 kw. The sales reps are telling me that since the Garmin CMR 404 open array radar has a narrow beam (1.8 degrees), I will be able to find birds. My other option is the Furuno system. It costs a little more, but has 6 kw, and will not have XM weather.

Since I'm not inclined to believe a salesman outright, does anyone have any practical experience seeing birds with the Garmin CMR 404 open array radar?? Does his logic about the narrow beam sound plausible to any electronics experts out there?

I am interested in any replies also, because I have the Garmin network now with the radome and would love to have the open array. Very happy with the network so far.

Have you looked at the JRC monochrome 6K open array for around $3200. They used to make furuno's stuff.

They include the instructions for seeing birds on their website.

Sorry no experience with the Garmin.

Correction- JRC made all the major components for RAYTHEON...

I was this close to getting the 404 unit unitl I looked at the dimensions - almost two foot high off the t-top - too much for my bridge I gotta get under.....

Still trying to get some first hand info, but the indirect information I've been getting so far has all been positive. The Garmin does have a narrower bandwith than any other 4kw I've looked at. It's even slightly narrower than the Furuno 6kw, which seems to be the standard for tracking birds on a small center console.

The information I've been reading about marine radars and tracking birds in general, suggests that almost any radar will track birds, depending on the right conditions, calm seas, clear visability, distance from the vessel, etc. At this point, I'm about 70% positive I'll be able to track birds with the Garmin under the conditions I'd want to be out fishing in anyway. I have one other expert to talk to today, and I'll chat with the Garmin people at the Fort Lauderdale Boat show later in the month before making a final decision. I'll keep everyone posted.

I know that the 4k units with open arrays wfrom raymarine and furuno will work, but with more power you will pick up smaller and fewer targets at a slighty greater distance.

So with the 4 kw you just need to be more educated and have better conditions like you say.

But the commercial units designed specifically for this service on tuna seiners are from JRC, and I believe these are 200kw systems

With the garmin 4K system, you will be able to see the birds by the time you are able to see them on the radar. Finding birds is not only a function of beamwidth, but also power. You are better off going with the Furuno 10.4" navnet with a 6KW or 12KW system. A 4KW is only good for navigating and weather.
