This product offering is for the Locator USBL Receiver - 100m only.

A complete system requires both a USBL receiver and a (beacon) transmitter. After calibration, transmitters are paired with specific receivers and should not be interchanged. The system works by syncing the clocks of a transmitter and receiver. The transmitter then sends a sound pulse once per second. The receiver uses time-of-flight to calculate slant range to the transmitter and phase measurements to determine the arrival angle of the sound pulse.
