Cone penetrometers, generally referred to as cones, are pushed into the ground at a constant rate on the end of a series of rods.  Measurements, which are instantly available, are taken every 2cm (see guide to CPT).  A huge range of soil parameters can be gained as evidenced by the list of cones below.

To date, Lankelma has a repertoire of 17 cones.  The most frequently used  are the CF cone and the Piezocone.
