I am looking to replace my old garmin 198c. I have it down to 2 units, the Garmin 4212 and the Raymarine c120. I like the Garmin, but the sales guy at West Marine said the Garmin came out in 07 and is pretty slow. I played with the c120 at the store and it seemed faster. I don't plan on adding radar anytime soon, but I will add the sounder. Anyone that has tried either or both, I would really appreciate some feedback. Thanks for any help.
