What device is used to time the third return wave when sagging a wire?

Timing the third return wave is about capturing the exact interval between when the signal is sent and when the third reflection arrives. A stop watch is the most practical choice here because it offers simple, portable timing with enough accuracy for field use, without needing specialized equipment. The other devices measure different things: a dynamometer tracks tension in the conductor, a sag scope visualizes the sag geometry, and a specialized Unisag watch would be used for specific sagging procedures but isn’t the standard tool for timing this particular transient event. So, using a stop watch directly provides the needed timing to identify the third return wave interval.
