HOW DOES LAND SURVEYING WORK?
Land surveyors have to make precise measurements with special equipment, so they can determine the exact location of boundary lines. In fact, almost every property development project starts with a survey. There are several different land surveying processes, depending on the type of surveying that needs to be done. Construction or engineering surveyors study changes in property lines and identify the location of boundaries or roads. Geodetic surveys use satellites and aerial imaging to measure large portions of the earth, while boundary or land surveys are used to determine the location of property lines. Surveyors often use a theodolite, which measures horizontal and vertical angles between points. But they can also use different levels to help them with their work.
HOW TO MAINTAIN A TRIPOD OR BIPOD
A Seco tripod is easy to maintain without any tools. Start by unscrewing the stop guide, which separates the inner part of the leg from the outer. And once that’s completed, you’ll be able to slide out the outer leg. Over time, you may see the presence of small dings that can prevent movement and sliding, but it can be replaced as a part. You can clean the outer leg by flushing it with fresh water or by using an air hose. The point should also be cleaned and lubed, so it doesn’t get stuck. The design of the inner leg is simple, with a cone and cam that's located on the end. The spring forces the cone into the cam, which pushes it into the outer wall. This mechanism can occasionally get unlubricated. And if that happens, it won’t turn properly. You should occasionally take it apart, so it can be cleaned and lubed.
