This exclusive design makes extracting soil samples easier than ever. the Linksmaster Soil Profile sampler gives you an undisturbed soil profile 6 in. (15.2cm) deep, 3 in. (7.6cm) wide and 1/2 in. (1.3cm) thick. The hinge allows you to easily view the root zone and thatch clearly, with no bolts or screws to get in the way. The innovative design not only keeps the blades from separating when inserted into the turf, but also makes it easier to replace the sample after viewing.
