Leica GRZ4 Original Special Reflector


Leica GRZ122 360 Degree prism Total stations that use automated target recognition and lock technology are best paired with an omni-directional prism. This type of prism is more convenient for operators because they do not have to constantly align the prism to the instrument.


  • Professional GPR121, GMP101
  • Mounted in metal holders for the best centering accuracy, stability, and longevity.
  • The Beam Deviation of the GPR121 is less than 2" and for the GMP101 is less than 6".
  • Ideal for precision and long range distance measurement.
  • Basic GPR111, GMP111
  • Mounted in polymer holders which are unaffected by the elements, even when exposed for long periods.
  • The GPR111 has a Beam Deviation of less than 8".
  • These light-weight prisms provide sufficient accuracy for normal surveying applications.
  • Choice CPR105
  • The CPR105 patented Flat Prism provides two back-to-back reflectors, both having 0-constants.
  • The unique Cat-eye reflector provides an RL measurement range of 250 m.
  • Ideal for traversing, since the prism can be measured from both sides without requiring rotation.
  • GRZ4, 360° Reflector: Suitable for all robotic TPS work performed with a survey pole. Large rubber mountings protect the prism. Overall 3D pointing accuracy of 5.0mm. When aiming on a side marked by a yellow arrow, an accuracy of better than 2.0mm can be achieved. ATR range of 600m (2000ft).
