Wireline core barrels eliminate the major time consuming operation of using standard double tube core barrels - pulling, stacking and lowering drill rods each time the core barrel is full.
 
Using a wireline system, core is recovered quickly by retrieving the core-laden inner tube directly through the drill string. The rods remain in the hole until the bit needs to be replaced. This has major cost advantages when drilling deep holes for mineral exploration.
 
The new MKII™ Spearhead Assembly consists of a redesigned spearpoint and spearhead body for added strength and safety. The new innovative design features:

70% increase in pull strength and 50% increase in bend strength that prevents the assembly from working loose

Self-lubricating plunger that eliminates corrosion and jamming, and keeps the spearpoint centered in multiple detent positions

Full compatibility with current Boart Longyear head assemblies and the Q wireline system

Fully assembled spearhead available for purchase or individual parts offered for easy assembly

Core barrel head assemblies can be upgraded through a simple conversion in the field by removing a single pin, replacing the spearhead assembly, and returning the spring pin
