What is the primary function of the "target lock" feature on a radar gun?

The primary function of the "target lock" feature on a radar gun is to confirm and hold the speed reading for a specific vehicle. This feature enables the operator to pinpoint a particular vehicle's speed and capture that reading, ensuring that the data recorded is accurate and reliable. When the target lock is engaged, it minimizes the risk of interference from other vehicles or objects, which can lead to erroneous speed readings. This capability is crucial for law enforcement to gather precise evidence when monitoring traffic speeds.

In addition to confirming the speed, the target lock feature ensures that the speed data is maintained on the display even if the vehicle briefly moves out of the radar beam. This function is especially important in dynamic traffic situations, where multiple vehicles may be present, and quick calculations are needed to focus on a specific target vehicle.
