The hardware is limited to 31.5' (~ 10 meters). The limitation is on the design of the receive amplifier's gain module (and noise floor). Generally scaling this to an integer of 32767 results in a precision of just over 1 tenth of an inch (or 1/3 (...) (25 years ago, 26-Mar-00, to lugnet.robotics.handyboard)
