  • Gerald W. Mahun


Surveying instruments are very durable, but delicate and precise pieces of equipment. No matter how well an instrument has been adjusted, rough handling, temperature variations, humidity, and a host of other factors can quickly affect its precision. The safest rule a surveyor can follow is to keep an instrument adjusted, but then use it as if it is not adjusted.
