The deep search metal detector range includes detectors for detecting arms, ammunition, mines and improvised explosive devices up to 7ft underground. These detectors are based on the internationally proven principle of low frequency pulse induction for high reliability and operational simplicity. It is suitable for detection of underground ferrous and non-ferrous metals such as copper, brass, silver and aluminum.

Deep soil compaction is a method of ground improvement and to stabilization of wastes and slopes with danger of liquefaction, determining the modulus of deformation and shear strength parameters of loose rock. This process is carried out by vibration, falling weight and blasting methods. It can occur where equipment traffic is heavy, or cultivation occurs repeatedly at the same depth.
