Introduction:
Leica GMP111-0 mini reflector prism with bubble, pole and spike set.
The GMP111-0 offers high positional accuracy due to its small size. It is mounted in a polymer holder with 1/4" thread fittings, has a built-in leveling bubble and is supplied with the GLS115 four-section pole and attachable spike (1/4" thread).
This setup allows a point to be measured with very high precision.

Prism Holder Accuracy
Prism accuracy is determined by the physical location of the prism in its canister and then to the prism holder. Certificates of compliance are available upon request. Leosurve prism accuracy is 1 mm or less.
Survey Prism Offsets
Some Surveying Prisms have an offset due to the fact that the transmitted beam from the EDM takes longer to enter and exit the prism. The longer time translates to a longer distance measured. The distance is corrected by using an 'offset' and/or positioning the prism in relationship to the plumb line of the prism holder. Common offsets are 0, -17.5 mm, -30 mm, -34 mm, and -40 mm. The offset is determined by multiplying the height of the prism against the refractive index of the glass used.
