As one of the four great inventions of china, compass not only has possessed great promoting function for the politics, economy and the development of culture in ancient china. After being spread to the west by various ways, it has also had a great effect on the history of world civilization. In modern society, compass plays an important role in cross-country orienteering. |
Compass always reminds me of my cross-country orienteering teammates and the days we have spent together. The most memorable day must be the day of my first orienteering on a mountain. It rained heavily the day before the game. Therefore, the mountain roads were muddy and slippery. It was the day shortly after I had joined in the team. I could not use the compass and the map location identification was quite poor. In the single player race, I ran to find the order point mere with my poor location identification. Back and forth as I ran and found the wrong points again and again, still could not find the thirteenth point out. I knew that I must have taken the wrong information. My shoes were wet and tore, so did my trousers and clothes. Finally, I had to give it up.
When the race was over, not surprisingly, I was the final one. And I was the only one who had not finished the game. It made me feel frustrated. My teammate asked me what had cost me so much time. When the reason was being told, he almost screamed at me:“why not used the compass to find whether your direction is right or not”? No why, I just didn’t know how to use it. This race had afforded me a useful lesson and after that, I practiced used compass in every orienteering that I took part in. If you are an orienteering enthusiast, the compass will be an essential teammate.
Before using the compass, you should match the map with your actual location. It can help you to detect your location and your destination. What you need to do is finding out one or two symbolic targets to help you realize the correct position. Besides, the apparatus should not be located near the magnetic material so as to avoid the loss of magnetism. For keeping the appearance of the compass clean, please don’t wipe it with your hand or dirty cloth.
It is widely used not merely in orienteering, also in other outdoor sports items like hiking and mountain climbing.
