Choice of equipment with two or three penetrometers

Choose equipment with two or three penetrometers?

Obviously the complete equipment (dynamic + static + probe group), would allow us to respond exhaustively to all the situations that can be encountered by conducting site surveys.
I believe that a static endowment + probe or dynamic group + probe group, allows to answer the 2 basic questions: “how consistent it is and what it is”.
With the static and dynamic penetrometric test a test is carried out on the geomechanical response of the land, while with the survey the nature of the land investigated is verified.
