What is it?
The PRISM-GAGE™ is a right angle prism with precision measurement lines inscribed on one face of the prism. When viewing through the PRISM-GAGE™, these graduated lines are superimposed on the turf so the viewer may measure the actual height of the turfgrass and thus be able to compare it with mower bench settings. The observer may also inspect the "quality" of cut by comparing the turf over the viewing plane of the prism.

How it works
Lines are inscribed at .10 intervals to .5 inch, then at .75, 1.0, and 1.5 inch. They appear superimposed on the turf enabling the observer to determine actual height of cut. By slightly tilting the prism, a larger overview of the turf may be seen to observe the "quality" of cut.

Optional Film Transparency
The film transparency is an overlay with graduation lines at .025 inch intervals which allow the user to more closely measure the height of cut.
