Stopwatch

What this one is for

• Counts up from zero
• Lap and split times
• Hundredths of a second

Counting up answers a different question from counting down: not how long you have, but how long it actually took. Laps record the pieces along the way.

Worth knowing

• Counts up from zero with lap and split times.
• Use it to find out how long something takes, then set a timer for that.
• Hundredths of a second, which is enough for anything short of sport science.
