Methods and apparatus for integrating an electromagnetic navigation system and a tool and aligning the tool with a target are presented, including a sensor tool, a tool, a field generator, a display, and a computer. The sensor tool attaches to a target component in a unique position relative to target features. The field generator is fixed relative to the tool except in rotation about a tool axis. The display is adjustably mounted to the tool and automatically adjusts image parameters. Target registration and error compensation methods are provided. The system detects magnetic field and signal disturbances that may lead to inaccurate navigation, filters navigation data, and adjusts filtering parameters based on detected conditions. Apparatus for proximally locking an IM nail such that a clear passage through the cannulation of the nail is maintained are provided.
