Surveying Prisms unleash the full potential of electronic distance measuring devices (such as total stations) by increasing their range and accuracy. Surveying prisms come in various shapes, sizes, styles, and materials. All the prisms have high-quality optical reflective glass covered with a coating that resists and protects your prism from dirt, scratches, and fogging. It also maintains surveying prisms’ degrees of reflection. Whatever prism you decide on, you will be more than satisfied with the useful and efficient features our survey prisms have to offer.
