Take the guesswork out of estimating canopy coverage. Sample forest canopy composition vertically, or sample ground cover and surface conditions horizontally. An excellent ecosystem management tool, the GRS Densitometer is simple and accurate, with repeatable results. Use by gathering data from equally spaced points on a transect. Sight through the densitometer, leveling the horizontal and vertical bubble-vials, and aligning the sighting marks. If vegetation intersects the vertical line of sight, the characteristics of that point can be recorded.
Includes a lanyard and instructions for use and maintenance.
