Set up for most chronographs at the range takes a few minutes - the Magnetospeed being the exception in this thread.
The overwhelming majority of users simply want to know how fast their bullets are traveling. I suppose it all depends on whether or not you use a busy public range, or have a quiet place to test.
Safe Shooting!
