Default Best radar package for small boats ( 21 CC with T top ) ?


Actually two questions:

1. What's the best radar package - unit and arc for small center consoles ( 21' has T Top ) ?

2. When is the radar most useful - given my boat has a top end GPS and two radio's.....

Appreciated.

1: For a stand alone unit the small JRC unit is pretty good for the money as are the Furuno units

2: Fog and at night.....it shows you what is actually there as opposed to what is supposed to be there like the data on you top end gps/ or the boat with out running lights coming straight at you

Okay: You asked for it. Don't waste your money. In order to have a decent (furuno 4KW or better) unit. You need the ability to mount a CRT and either a large radome or (preferably) an open array antenna. To do that you need voltage that your outboard doesn't produce. What you will wind up doing is buying a LCD unit that has 1.5 or so KW of power. That's about all your outboard can keep the voltage to.

Why not to buy a 1.5 KW LCD? Your buddy has one and the picture is great...right? Here's the real deal. A wimpy LCD unit will give GREAT resolution on a clear day or a clear night. BUT: Heavy rain? Forgetaboutit. Doesn't have the power to punch through the heavy stuff. Which incidentally...That's when you NEED your radar.

The typical center console does not have the height above the water to give you decent range on a radar unit anyway. For example even my 37' Lafitte skiff can't see real good detail beyond the 6 mile range. It's open array antenna is at least 15' above the water and it is a 4KW unit (36 mile range). I could only imagine an LCD unit with less than 2KW 8' above the water.

Besides.....how often do you navigate crowded anchorages in near zero visibilty anyway? If your answer is very frequently.... then ignore everything I just said. But for the most part...when it's that crappy outside, do you really go anyway?

I have a Garmin Radome 18" radar and it works fine with my outboard engine. I have it running with a Garmin 4212 MFD.

Works great, no problems, my boat is 21' 8" with a T-Top putting the radar right at 9 feet above the water. I recommend you get the 18" Garmin radar unit and a Garmin MFD.

Best bang for the buck on a small boat- one that will work with your fishfinder or gps unit. If your existing equipment is
compatible you should be able to buy a add on radar unit for 900 to 1500 bucks. As mentioned above no more height
above the water than you will have the range will be limited but, it will give you some warning of what is approaching you.
Unless you will use it frequently I would not spend more than this.

First of all LCD or CRT make no difrence ( other then crt is over weght and dated for small boat use and crt wastes power) on how well it works . I would take a LCD easier for4 me to see and take up less room as far as range do you really care whats more then a few miles away ?? its whats near you you have to worry about , with that said a 4 kw woul be great but you would befine with a 2kw and 18" dome I have used some with a 15" and the don't work that well ( bottom line furno and JRC ) 1715 furno works very well , the only time I use my radar on long range is looking for storms . when I really need radar I set it on 1 or 2 miles .

I'm not worried about running over 4 good ole boys in an unlit jon boat heading to their favorite trout hole if they are 6 miles away. But at 5 in the morning with no moon I will miss them when they cross the waterway ahead of me because my radar saw them . How much do you trust your GPS, was that thud you just heard and felt a buoy that your GPS says is way over there but has been moved in the years since those charts were made, my radar showed me its exact position.
People give two reasons for having radar; collision avoidance (like I said I'm not worried about hitting something 6 miles away) and storm tracking. My Furuno 1715 on my 21 and a half ft boat does a good job of tracking storms alot further out then 6 miles. But there is a third reason to have radar; navigation, at 5 in the morning with no moon I have my radar to back up what I see on my GPS, and I have my GPS to back up what I see on my radar. I know that on a pitch dark morning without my GPS I can navigate out the creek, up the waterway and out the inlet using just my radar.

To the OP, get one of the JRC or Furuno units and learn how to use it, its an invaluable aid to navigating in low vis situations.

Thanks - seems to me that radar would be useful for a mile or two most. Anything beyond that really isn't a threat - yet.
I think I'll pass on radar. I've been in some fog, but tend to fish good weather, and navigate ok with the big Lowrance X-111.

Good point , seeing birds on a 2kW is possable if you play with it but it realy it not good at it ( if you see the birds on radar you can see them with your eyes) a 4KW is fair better if its open array yes a 6KW would be much better
But rember we are talking about a 21 foot boat here a 6KW radar maybe a liltle large for it I do not think you will find a 6KW thats not a open array .

I used to have that 2.2kw furuno on my old contender...that radar was awesome and very affordable. Picked up structures as small as little grass mats floating on the surface. Also picked up weather very nicely. I now have a furuno 4kw and I can't seem to make it work as well as my old 2.2K. Definetely take a look at it

I have Furuno 1712 which is I guess similar to the 1715.It`s 18" dome 2.2 kw does exactly what I purchased it for.

I have the Garmin 2KW, 18" enclosed radome black box radar (I can't remember the model number) with my new 4212, and too tell you the truth, it isn't very impressive. I have heard lots of good things about Furuno, I would but that if I had it to do again.
