Requires two ranging poles and an assistant.

The prism is held steady over the corner point, and a ranging pole is set up at the far end of the baseline.

An assistant then holds a second pole in approximately the correct position at 90° off the baseline.

The person holding the prism views the two pole images in the split-view window, and when the two two images appear in-line in the window, they are at 90° on site.
