The Ultra 4 is made for the archer looking for absolute peak performance in their stabilizers, optimally balancing the needs of a wind efficient small diameter, stiff carbon layup, and lightweight system. The Ultra 4 is less affected by wind than any other rod on the market, including the already incredibly narrow Ultra 3 and Vektor rods, making it ideal for unpredictable outdoor competition. Its light weight allows archers to shift the overall mass of their system further out to the end of the rod, maximizing performance for any given total weight, all while still retaining a crisp feel thanks to the stiffer carbon weave.

• Steve Wijler Edition Tungsten Damping option includes 3oz of tungsten powder added into the distal end of the rod, doubling as a dual-density vibration damper and internal weight, further cutting down wind drag by reducing the number of weights on your rod.

• C-Spine stabilizer spine measures how much a stabilizer flexes under load - Higher C-Spine indicates a weaker stabilizer and lower C-Spine indicates a stiffer stabilizer.
