Abstract: The present invention provides a viewing scope adapted to be mounted on a device, such as a rifle or camera. The viewing scope may include a body module, an objective module, a test module, and a control module. The test module may be configured to test the performance of the scope. The control module may include a series of user inputs that can be accessed and activated by a user without requiring the user to move his or her visual focus from the scope.
