When the inner-tube is full, a device called an overshot is lowered down the hole via a wireline cable and brought to the surface by use of a winch.
Once the inner-tube assembly is at the surface, an empty inner tube is lowered into the hole so drilling can resume
There is one overshot for each size of core barrel. This is a recovery device lowered on the wire rope to recover the inner tube assembly containing the core.
