The Sirui VH-15 Fluid Video Head, pronounced Soo-Ray, is a precision-machined aluminum video head that supports up to 22 pounds. It features a fixed spring counterbalance that helps bring the head to a neutral position and variable tilt drag, with 0 drag for fast tilt positioning; pan drag is preset and fixed. The pan and tilt locks allow you to set a shot and lock off the head so it doesn't move for lock-off shots.
