Summary:Devices, systems, and methods for retrieving inner tubes following core sampling are disclosed. Exemplary systems include a drill rig having a drilling axis. The drill rig can have a mast having a longitudinal axis and opposed first and second ends, the first end of the mast being configured for positioning proximate a drilling formation. A drill head can be configured to impart rotation to a drill string. The drill head can be configured for movement about and between a first position in which the drilling axis extends through the drill head; and a second position in which drill head is spaced from the drilling axis.
