This function was especially developed for the needs of airplane pilots. Even during timing, with a single press of a button, the stopwatch can be started again from zero instantly. This allows for several split times to be recorded without any delay.
This timer is used for timing the start of a regatta. The countdown timer can be set for up to 10 minutes. It emits a sound signal for each elapsed minute and for each of the last 10 seconds. Automatic reset after the time has elapsed.
