For years, L-Bar mini prisms have been an industry standard among surveyors. With most models offering a copper-coated prism made from high-quality optical glass, these products have been prized for generally long working ranges and accuracy.
But L-Bar prisms aren’t always ideal––especially when it comes to attachment, flexibility, and protection from the elements.
Temporary use on anything but a completely flat surface, for example, is virtually impossible to pull off with an L-Bar. While the prism is detachable, surveyors still need to drill and screw to mount the L-Bar itself.
As newer, more advanced surveying tools enable crews to be more efficient on-site, surveyors are increasingly switching out their L-Bar prisms for lighter, more portable alternatives. Chief among these are Rothbucher’s line of 180º tilting and 360º rotatable mini prisms, which offer a number of major advantages over traditional L-Bar prisms.
