RSMP390 Mini-Prism - Perfect for Leica & Geo-Max Total Stations

The RSMP390 is a twistable, extensible 25.4 mm mini-prism made with a rugged plastic housing system.

When using the mini-prism RSMP390, the prism can always be aligned precisely with the measuring instrument. The 25.4 mm prism can be turned in a radius of 360º so the same survey point can be measured from different directions. Bridges, rail lines, buildings and other structures can be measured more quickly and precisely.  Mounting adhesive enables quick and simple installation even on difficult surfaces while provided holes enable attachment with dowels or screws.

Reflectorless measurement ranges of 600 m and more are possible when using the RSMP390 mini-prism and when sighting known measuring points with robotic total stations, it is possible to achieve ranges of up to 1000 m.
