The Triple Prism Holder is a precision surveying accessory designed to securely hold three prisms for use with total stations and other optical instruments. This rugged holder tilts a full ±360°, allowing surveyors to rotate and position the prisms precisely for accurate measurements on site. It offers selectable prism offsets of –30 mm or 0 mm, enabling flexibility depending on your instrument’s calibration and measurement setup. The holder is fitted with a 5/8″ x 11 prism pole adapter at the base, making it compatible with standard prism poles or tribrach adapters for fast deployment in the field. This accessory is ideal for land surveying, construction layout, and geodetic work where multi-prism reflector setups improve visibility and data quality.
