UTFAN- I had to send my 787(front finder) back. We updated it with Version 4.48 which came from HB. Richard Williams looked at it and said it was fine but i know for sure there is not a spot on KY Lake that is 1267 ft deep. Our display is messed up and with tvg off it is solid red & blue from top to bottom. Our 997 was messing up until richard updated with his card. I will know the verdict tommorrow of it from Eddie Kenddrick. I will report on it. We had solid blue line across at 3 ft deep and would loose bottom quick or have light blue(weak) returns.
