1A20.60 Reaction Time

Cover 3/4 of a stop clock face. Push the stop button when the hand shows. Reaction time stick works much better.

This image shows a large box-style plug-in stopwatch with three-quarters of the dial covered with paper. The stopwatch appears to have a trigger switch. A ruler, the 'reaction time stick', also appears.
