Grass Height Prism Measuring Gauge is made from stainless steel that retains a solid high quality glass prism that bends light at 90 degrees to measure the height of fine grass in metric and imperial.
You can compare it with mower settings to see if the results you are getting are acceptable.
The quality of cut may also be checked by comparing the turf over the viewing plane of the prism.
It is ideal for inspecting golf greens, bowling greens, baseball infields, cricket pitches, grass tennis courts or any fine turf surfaces where mowing accuracy is important.
It comes complete with protective box.
It measures from 1/16th - 1 5/8 inch (1 mm - 40 mm).
