Arrow 3S Overshot

The Arrow 3S auto-lock overshot combines with the DiscovOre head assembly combine to create a revolutionary new core barrel system that provides safety, speed and simplicity. The design of the system has eliminated the weak and potentially hazardous components of a standard core barrel, the spearhead and spring pins.

The Arrow 3S offers a much faster descent into the borehole. It features an arrow-shaped, spearhead design for minimal water resistance and has a smaller cross-section area, both of which allow it to cut through water quickly and reach the target faster. Depending on the size of the borehole, the Arrow 3S is up to 50% faster. It is designed to be centralized in the drill string for a faster, smoother pump.

Designed for use with the DiscovOre head assembly, an adaptor is available so the Arrow 3S can also be used with all standard head assemblies on the market.

Faster descent
Improved conversion head for all hole orientations
