Positioned between compact lightweight investigation rigs and larger drilling units, the GEO 305 is designed as a true multipurpose platform capable of performing a wide range of drilling methods, including wireline coring, hollow stem augering, rotary drilling, DTH hammer drilling, SPT testing, dynamic sampling and monitoring well installation. Its flexible hydraulic architecture and modular configuration allow flexible configuration according to drilling conditions and project requirements. Despite its compact footprint and transport-friendly dimensions, the GEO 305 delivers drilling performance typically associated with rigs of a higher class and enables deeper boreholes and improved performance in more complex ground conditions.
