    6m Sensor

    Beyond transducers, increasing range needs high sensitivity op amps and a good bit of noise rejection. The unit above has a good deal of it set up, but it is the cost of 4 basic ultrasonic rangefinders.

    For anything beyond 20 feet, you'll more than likely end up using a laser ranging solution.

    Expense goes up by a factor of 10 or so.
