I have this thing made by a company called Calculated Industries, the Dimension Master Plus (TM) Tapeless Measure/Calculator that's designed for architects I think. It has a phased array of three sonar actuators (they're 1inch diameter), and it advertises roughly a 3deg. beamwidth, which is believable based on playing with it. Good resolution too--it gives millimeters...not that anyone would care. I don't know how we got it or where, so don't ask, but it probably cost a few hundred $$$. Dimensions are about 3"x6"x1", weighs less than a pound with batteries.
