Thats about what I got from my Furuno 4KW dome. I have a oportunity for around $2,000 to change over to a 10KW 4' Open Array. Now on a big tall sporty or sailboat clealy this would give me more of everything. But on a CC with the radar being only T top high how much is there to gain?
Beamwidth is allot narrower so separation will be better, but I have no issues with my current setup distinguishing between targets at my normal operating range of 1.5-3 miles. What I'd be looking for is extending my bird finding out to say 5 miles or so. I used an online calculator to see what the radar horizon is and I show about 4.5 miles to a water level target and around 8-9 to a target 5' high (birds tight to the water) Is this a reality to "see" birds at this kind of distance from a CC with only a T top regardless of how much power I push?
The only down sides other than wasting $2000, is the Array setup is about 50# heavier on my T top and it will suck a TON of juice compared to the dome. But to double my bird finding range I'd be willing to deal with that.
Opinions? Anyone made this upgrade?
