Not all surveying tools are the same, and some are better for certain jobs than others. Optical or laser plummets, for example, might be better options than plumb bobs in situations where the environment is too windy, or the job needs to be done more quickly. Tribrachs enable the use of optical or laser plummets, but they can also help surveyors switch instruments without having to change the instruments’ location.
There are a lot of manufacturers of surveying instruments in the world, but Sokkia has proven itself to be one of the world’s leading brands. Find Sokkia tribrachs and more here on Engineer Warehouse.
