I'm looking at putting a radar on my 26 ft boat. It is used out of Valdez. I've been looking at JRC 1500 - 2kW w/16nm range. Boatersworld has a great deal on the entire set-up (under $900). Seems like 16 miles is plenty of range to avoid things that go bump in the sound and even out to Knowles Head. Reviews I've read seem really good on this JRC unit. Do I need to step up to the 24nm unit? Any feedback on the JRC radars?
