The DiscovOre head assembly and the Arrow 3S auto-lock overshot combine to create a revolutionary new core barrel system that provides safety, speed and simplicity. The new design has eliminated the weak and potentially hazardous components of a standard core barrel, the spearhead and spring pins.
The DiscovOre ‘s safety measures are automatic so no hands-on interaction is needed. It does not add time to the coring cycle so productivity is maintained. It features a unique latch design that is robust and easy to replace. With its leveraged latches, inner tube jamming is virtually eliminated. A reduced length makes it ideal for underground drilling. What’s more, it converts quickly from underground to surface applications.
The Arrow 3 S features an arrow-shaped design for minimal water resistance and has a smaller cross-section area, both of which allow for a faster descent in to the bore hole. Depending on the size of the bore hole, the system is reported to be up to 35% faster going down the hole. It is designed to be centralized in the drill string for a faster, smoother pump.
