Had my Furuno color video on my Grady for over eleven years, sold the boat and it still works like new. I don't know much about others but, I'm sold on Furuno's and am installing a NavNet system on my new boat. Two 10.4's and a 7" with the works. RadarMarine knows there stuff also. Talk to Bill Pulse (bpulse@radarmarine.com) Most of the guys I know that fish Alaska also recommend Furuno's. smile
