What To Look For In Used Surveying Equipment

Before starting a construction project, the building area needs to be surveyed in details by experienced and qualified land surveyors. Surveying is a tough job that requires a wide range of high quality surveying tools to be used, such as: levels, total stations, geodimeter, theodolite, recievers, planimeter, GPS equipment, and many other surveying tools. All these pieces of surveying equipment can be extremely expensive if are purchased all in once. If your financial budget is tight, it may be more reasonable to look for a used surveying equipment for sale. Today there is a broad range of available used surveying equipment from which you can choose, instead of buying brand new models which can be quite expensive. Even on the Internet, you can search, compare and buy the surveying equipment that you are looking for. Carefully maintained second hand surveying equipment can be as useful and effective as the brand new surveying equipment. But however you should pay attention when looking for a used surveying equipment for sale. What you need to look for is clearly good quality, functionality and durability. You should also be aware of certain features which are unique to a specific surveying tool. The following text will highlight briefly what to consider and what to look for when buying second hand surveying equipment.

Used Theodolite

In order to measure angles with high precision you will need a theodolite. The theodolite is used for measuring horizontal and vertical angles, and the results are shown on small LCD monitor.

When searching for a used theodolite, look for one with a clear, smooth and undamaged LCD monitor that has no cracks, abrasions or cloudy spots. You should be able to read the results with ease once they appear on the monitor. If there is some wear on the exterior of the theodolite, this may indicate that the theodolite was not maintained properly by the previous owner, or that there are some internal problems that can cause the theodolite to breakdown. It is highly recommended, if it is possible to test the theodolite before buying it.

Used Total Station

The total station is another useful piece of surveying equipment that needs to be included in your surveying toolbox. This device combines the functions of several other surveying tools into one functional unit. The total station can clearly help you a lot in many surveying tasks. Many online sites in Australia offer a broad range of available surveying equipment for sale that include total stations, either in new condition or second hand. Just like any other second hand device, there are some elements and points that need to be closely considered and checked so that a proper working total station can be purchased. You need to be sure that all elements that are included in the used total station are working properly. For example, the theodolite which is attached to the total station may not be working properly even if the distance measurement works fine.

Used Geodimeter

The geodimeters are generally used by surveyors if some measurements need to be made at night. This particular surveying device uses light waves in order to measure distances between different points. A special prism is required for the geodimeter. This prism is placed at the end of the distance that needs to be measured. The prism reflects the light waves back to the geodimeter for accurate measurement. Again, when you are looking for a used geodimeter, make sure that all elements are functioning properly. The prism, which is the most important element of the geodimeter, should be in excellent condition. That means without any cracks, marks or smudges. Also a second hand geodimeter needs to be powerful enough to measure the distance accurately.
