I am considering purchasing a new HB 798ci HD SI. Some of the outlets are marking these units down below $700 since HB is discontinuing the 700 series. My concern is this: is the screen to small on the aforementioned unit to see much detail in the side imaging mode? Would I be better of with just a down imaging unit? I am currently using an old 727 unit that is black and white. I would really appreciate hearing from some 798 users.
