    Abstract: A soil or snow probe which incorporates a load cell in the probe head and also an accelerometer so that a vertical strength profile of the snow or soil can be established. The device does not need to be driven at a constant speed and can be manually driven into the soil or snow. The resistance to penetration is measured using a load cell which incorporates a low duro polymer selected for its ability to behave like a non compressible fluid. The device is portable and provides data quickly.
