If there is another object in the water in the area, mine, CM, etc, yes.

Otherwise, there are certain sonar conditions that will create duplicate returns, at the same bearing but varying the distance. Usually the fake return will not persist over a couple more pings. (It will move to some other location) (Besides, you can't mark the false one)
