Arm section lengths (pivot-center to pivot-center) in PRO, Tiffen, Xarm, and NB models: whether larger boom range derives from longer sections or wider opening angles.

What the thread found

  • PRO arm section measures approximately 9 15/16 inches overall length, with pivot-center to pivot-center distance of approximately 9 3/16 inches.
  • The NB arm achieves its large range primarily through thinner bones that collapse further, comparing roughly equal or slightly shorter in length than a PRO Titan arm.
  • Tiffen G-70 sections are estimated slightly longer than the Titan.
  • When measuring arm sections, always measure from pivot-center to pivot-center for consistent comparison.

Depends on

  • Exact specifications vary by arm generation and configuration.
