1. A core barrel head assembly comprising:
a proximal end portion comprising a check valve assembly;
a distal end portion; and
a hollow spindle extending between and coupled to each of the proximal end portion and the distal end portion, wherein the hollow spindle has a proximal end, a distal end, and a bore that extends continuously through the hollow spindle from the proximal end to the distal end; and
at least one bearing received within a proximal end of the distal end portion, wherein the at least one bearing is configured to rotatably support the hollow spindle relative to the distal end portion,
wherein the distal end portion comprises an interior wall, wherein the hollow spindle has an exterior surface, wherein the interior wall and the hollow spindle cooperate to at least partly define an interior cavity that is configured to receive at least one electronic instrument therein, and
wherein the bore that extends continuously through the hollow spindle provides fluid communication through the distal end portion of the core barrel head assembly to the check valve assembly.
