Abstract
A turf inspection instrument offering an expandable depth of field and enhanced vertical scale for observing and assessing turf conditions is provided wherein the instrument includes an end wall having a gauge surface carrying graduated measuring indicia thereon, opposing longitudinal ends, and arms extending therefrom to form a substantially U-shaped frame having an open end opposite the end wall. The end wall further has a beveled bottom edge for satisfactory turf penetration. A selectively adjustable viewing assembly is carried by the frame (i.e., between the arms) substantially parallel to the end wall for movement with respect thereto. The viewing assembly includes a prism and arm engaging members adapted to support the prism moveably upon the arms, with the prism being tiltably received by the arm engaging members. A turnbuckle assembly connects the arms near the open end of the frame. Rotation of the link of the turnbuckle assembly permits binding of the selectively adjustable viewing assembly in a fixed position between the arms.
