  • The tool can be opened hydraulically without a free-fall opening cone, which enables operations in highly deviated wells
  • Shear pins can be adjusted at the rig site, which enables the operator to adjust opening pressures to specific well requirements
  • The absence of an opening cone along with PDC-drillable materials accelerates drill-out and saves costly rig time
