The Davis & Sanford ProVista Airlift Tripod w/FM18 Head and W3 Dolly w/3" Wheels Kit from B&H Photo provides rigid support for those who need strength more than versatility in height options. The Airlift version features a pneumatic cylinder in the center post which provides smooth and easy floating action height adjustment for cameras weighing from 2 to 12 pounds.
The Davis & Sanford W3 Universal Folding Dolly can be used with all standard tripods, is adjustable, and can be folded up to a compact 24 x 7" size. 3" ball-bearing rubber/metal wheels feature "step on brakes" that lock and unlock the rolling and swivel movement of the wheels.
The ProVista Airlift tripod assembles to its working height very quickly, thanks to twist locks that only require 50% of a rotation. With double-strut top leg sections for extra stability, a center brace with lock, and non-skid rubber feet, this tripod is perfect for field, studio, educational or industrial applications.
