A matter of preference. Sail boats like them because they don't have to worry about the sails getting caught. You can have them on and no one will know... Often people will tell you to turn it off in a harbor when you forget. I actually like to see the array turning. The radome is only available on the small units anyway.

The advantage to the dome is that they cost less.
The open array gives a narrower beam width so you get better target discrimination. (2 targets close by may show as one with a dome)

I don't think you can get a dome with greater then 4kw, but you can get them with up to 15" displays.

BTW, if installed properly an open array will not get water inside.

The arrays are stonger and MUCH better. You get much better detail when using an array. Much higher resolution.

PS- Why would ya turn off the radar when in harbor? I like to take the paint off the neighbords boats!! [img]/infopop/emoticons/icon_biggrin.gif[/img]
