This stopwatch has a calendar display, 12/24-hr. clock display (conventional/military time), and an alarm. The countdown timer counts down from a preset start point, and the lap counter tracks the number of laps completed. The elapsed time feature measures the total amount of time between the start and finish of an event. The split time feature allows time to be taken at different intervals during a race or test. The memory recall function allows multiple lap times to be stored for future review. The temperature/humidity/heat index display provides relative humidity, ambient temperature (in °F or °C), and the calculated heat index. A lanyard and battery are included.
