If one is trying out the MTC version without first mounting it to a rifle, it may seem impossible to stop on a desired setting. It is much more user friendly once the MTC is mounted. Having said that, of the Schmidts I own, all are standard DT's except for one. With adequate time spent shooting and dialing I believe it to be a minor issue. My lone MTC is the locking version which is unnecessary for my applications. As with everything else, there is inherent subjectivity as well as variances in user needs and preferences.
