Looking to replace my old FR8111 with a 6.5' antenna. This has been the main radar on the boat. There is a NavNet 3D with a DSR6a as the second radar. What are the differences between the 8125 and the 8122? From what I can see from the information on line the 8125 is a UHD radar and operates on 24 volts. What else am I missing?
Thanks
