Navigational compass, the direction finding machinery, is effective in finding direction that contains a magnetic pointer to align itself accurately with earth's magnetic field and act as a pivot to locate the direction. Modern navigational compasses, the measuring tool that consist of base plates with rulings measures the distances on map, and a rotating bezel to measure the distance of different objects and also possess a mirror to see the needle and the distant object at the same time. Now-a-days navigational compasses are marked in degrees rather than cardinal points. Gyrocompasses, the marine compass are preferred to magnetic compasses because of its multiple advantages in large ships and fluxgate compass is widely employed in small vessels. Far from these applications the shipbuilding industries and maritime business or travel use this mariners compass as a key tool, which is also effective in survey and for research in the navigation field. Common households as well as the corporate houses use it as a multiuse magnetic compass.
