SINGLE TIME ONLY
This selection will show only the time to the last shot
in a large format.
ROUNDS PER MINUTE
This mode is used for measuring the rate of fire
rather than time intervals. The screen layout is
similar to REVIEW DIRECT. After the start beep, fire
shots; the timer will display the rounds per minute
based on the number of shots and the time between
the first and the last shot. Shots recorded more than
199 .99 seconds after the start beep will render
readings invalid until the unit is restarted. The
ProTimer BT can detect shots at rates up to 1800
RPM.
