Cross Staff-

Essentially, the cross staff allowed you to determine your altitude while at sea as well as your latitude and longitude In the cross staff the man would line up the cross staff and the sea. The way to use this tool is by lining up the bottom half of the cross staff. Also the man must line up the top of the tool with the sun. The horizon is lined up with the bottom half Of the cross bar. Once you find the altitude and depth you can then mathematically find your latitude and longitude. At this tool's core, it helped sailors for latitude and longitude. This enabled them to navigate. This was made possible because of the scale that was on the graph. This was revolutionary because once you knew where you were, then you could travel to different places in the world. If you knew where you were than u knew where you could be.
