Stable and durable, the Sokkia ATP1 360 degree prism is one of the industry's best in prism accuracy. Its reinforced center post supports a range of quick-release mechanisms on tribrachs, standard poles, and other accessories. It is also an essential accessory for the Sokkia SX Robotic Total Station and useful for most robotic work.
The Sokkia ATP1 robotic prism has a 5/8" female mounting thread on the top and bottom of the prism for dual attachments. Designed for surveying tasks requiring a survey pole, the prism works in a 360° radius and an accuracy of ≤5 sec. This is accomplished by six precision-machined corner cubes mounted in a rugged housing with solid metalcore. It has the same -7mm offset and sizing with the current ATP1 prism. There is no need for extra spaces to make it compatible with other robotic pole graduations.
The Sokkia prism answers in finding a practical and compatible accessory for the Sokkia and Topcon robotic total stations. With a silver reflective coating, the device also comes with a protective velcro prism sleeve, a padded carrying case, and stainless steel adapters on each end of the prism with molded end cap covers.
