I used the 520c last night with the Michigan Lakemaster chip and it was dead on. Passing over a hump, it showed us right on it. This is our local lake that has an enhanced version on this chip. Others wont be as detailed. Shows our breakwater arms and buoys that are not on our background maps. It would be nice if both could use the one card but.....
