There is a ultrasonic sensor made by parallax that is pretty precise, to increase precision though you should probably know what temperature it is in the operating environment and code for that accordingly.
I was curious of how the resolution of sonar was when sensing objects ~1m away. Could it be used to map a thin pole that was an inch or so in diameter?
