The Harpoon comes standard with both mono and dual points, and the mono point can be positioned in the center or offset to either side. The straight frame makes for somewhat awkward foot placements, but the front and secondary points are well positioned for chandeliered ice, edgy rock climbing, and torsional support. The dual points have blocky horizontal wings on their inner sides that only limited the point's purchase in steep ice. The mono point lacks these wings and provides significantly better penetration and security. Climbing performance is good and reliable with mono points.

Dual-point wings reduce crampon's purchase.
