Surveying and construction has been at the forefront of all successful human civilizations since the beginning of time. Evidence of this is written down in plenty of history books; all one has to do is open and read to understand the significance of surveying and the extent of which construction work depends on it.
Traditionally explained as the science and technique of calculating the positions of 3D points and calculating the distance between them, the Egyptians are the ones who first used it (in recorded history) back in 1400BC, the purpose of which was to separate lands into plots so that they could tax people over it. In 1200BC the Greeks gave birth to geometry and used it to take surveying a step further. They also developed the Diopter; a unit that could be used to measure the optical power of lens, making it the first surveying equipment to be invented. The true importance of surveying was realized in 1800 A.D, when the boom of the industrial revolution increased the need for exact borders and governments realized the importance of improving roads, railway stations, canals and other public buildings. From such humble beginnings, surveying and construction have risen to one of the largest job opportunities in the world. Today surveying is used for anything from preparing maps to constructing bridges. A multitude of equipment has been developed to assist and make the job easier. Surveying tripods, magnetic locators and GPS equipment are some of the little equipment required for success. A green beam laser level is also one of the most critical pieces of equipment needed in the field of surveying and construction. It houses a projector that projects a laser beam, and can be fixed to a tripod.The end result is that a green beam is projected along the horizontal or if needed the vertical surface.
A green beam laser level is preferred to a red beam due to the proven fact that the human eye can detect the color green up to four times more than it can detect the color red. In construction and engineering terms, this means the beam emitted can be seen at a further distance in comparison with red laser beam levels and hence in most cases, don’t require detectors which save you a great deal in money.
Green diodes are excellent for interior designing and such, but they are generally more expensive than red diodes. For firms or workers who do all round tasks, green diodes are the best option. Online websites allow you to search deep so you can find the sweetest deals out there. Most diodes also comes with a great selection of enhancements that make it easier to view the beam and include large batteries for long battery lives and are constructed with a rugged body to withstand the harsh environments of construction work places.
