knowing that accuracy is at your fingertips. Whether you’re on-site or in the field,
this prism is an essential tool for successful surveying.
Features
High quality 360° degree prism.
Ideal for all robotic work performed with a survey pole.
Includes a padded case for safe transportation.
ATR range of up to 600m.
This reflector is designed for use with all robotic Total Station (TPS) work involving a survey pole.
It features durable rubber mountings that protect the prism. The overall 3D pointing accuracy is 5.0mm,
but when aimed at a side marked with a yellow arrow, an impressive accuracy of better than 2.0mm can be achieved.
The ATR (Automatic Target Recognition) range is 600m.
The lightweight reflector is passive, making it ideal for efficient operation without needing to direct
the reflector toward the instrument. It includes a 360° prism configuration, consisting of six corner-cube prisms.
This arrangement allows the measuring beam to reflect directly back to its source from any prism position,
ensuring uniform offset and accuracy readings from all sides.
Recommended for all robotic tasks with a survey pole, the reflector’s rubber mountings offer added
protection in case the pole falls. It comes in a padded case for secure transportation.
The GRZ4 provides an overall pointing accuracy of 5mm. However, aiming directly at one of
the three yellow-arrow-marked prisms can achieve an accuracy of better than 2mm.
