    This product is for…

    Multi-pitch and trad climbers who need one device for lead belaying, top/anchor belaying in guide mode, and rappelling. Suits anyone wanting a single plaquette-style device instead of carrying multiple tools.

    Worth noting…

    Wider aperture than key competitors is a noted functional advantage for two-follower top belaying. One host mentioned wearing out a first unit and returning to this model, suggesting normal long-term wear is expected.
