Designed for undisturbed samples from very soft and preferably very wet soils with minimal disturbance of soft cohesive layers such as wet clay or peat. Constructed from a long, tapered stainless steel, semi-cylindrical chamber, which is pushed into the soil, twisted and recovered to display a full and virtually undisturbed profile of peaty soil. Sharp cutting edges ensure easy penetration without twisting or turning which could agitate the sample. 

Requires attachment to cross handles or slide hammer for use.
