If you want to see out 30 miles you are going to have to mount your antenna pretty high. My radar is 19' above the waterline. Based on Furuno's radar horizon calculator (Radar Horizon Calculator) I can see a 10' high target at 9 miles and a 40' high target (ship) at 13 miles. So 30 miles range is of no value to me except that a 30 mile range capable radar will give better returns at my 9-10 mile maximum usable range.
