I'm thinking about getting the Raychart 425. How do you like it? I currently have a Garmin 168s and it is a good machine but I want more detail as is available in the Navionics chip. Is the Raychart hard to use? How good is the detail on the Navionics Chip that you have. I am also considering the new Garmin 182 that is supposed to have more detail than the Navionics on the Garmin Blue Chart Chip. As far as responding to what machine is a good choice, the boater must decide for what purpose is he using the machine? Does he want to go offshore? Does he want it simply to input fishing ground numbers? For me, I want depth contours and all the channels marked b/c I'm on the Great South Bay. My Garmin does not have the detail required when I'm looking for channels, etc.
