The 501HDV pro video head incorporates a number of improvements and updates in its design that provide for greater equipment safety and ease of use. One feature is a spring loaded counterbalance that can easily be engaged or disengaged for different filming setups via an easy to reach switch. The counterbalance ensures smoother tilt movements while protecting your equipment even when the tilt locks are accidentally left off. Improved ergonomics for the locks and knobs provide a more solid grip and better fingertip control. A secondary security lock stops the quick release lever from opening fully keeping you from accidentally releasing the plate (and camera) without meaning to.
The 501HDV has retained all of the best features of its predecessor which include separate pan and tilt locks, gradual tilt friction adjustment system, a flat base (with standard 3/8” thread), quick release camera plate and repositionable pan bar.
