I have the CP180, Its a nice machine but a bit difficult to learn, Not very user friendly. small 5" screen.
I have been looking into new units myself and the Lowrance is looking great, CB has a older one he got in a deal with 7" screen and he likes it, a friend just bought one and loves it.
He also bought the Navionics charts and says it has great detail. Has a nice 6.4" screen
I believe this is the model?? I will try to call him and make sure as I am about ready to pull the trigger on one.
