F5 Falcon receiver (locator) is a handheld unit used for locating and tracking a Falcon wideband transmitter. It converts signals from the transmitter to display depth, pitch, roll, temperature, and battery level, plus sends this information to the remote display on the drill rig. The receiver and transmitter must meet specific operational requirements for different global regions. A regional designation number is located on the receiver’s startup screen. This number must match the one stamped on the transmitter for proper communication.
