A tubular extension is coupled to the shroud and is slidably coupled to a main body. The main body includes first and second latches. The first latches releasably lock the device to a core lifter case assembly disposed within the core drill, to selectively prevent the device from advancing in an uphole direction within the core drill. The latching system operates to prevent the device from falling out of the core drill. Face orientator includes a plurality of pins which can move axially to provide a plurality of profile reference points to a facing surface of a hole to be drilled. The bottom orientator includes a plurality of balls disposed within respective braces.
