By popular demand, we merged our award winning Alta Pro tripod with our popular PH photo pan heads. Alta Pro tripod kit has unmatched versatility and stability and enables more angle possibilities than ever. Its innovative Multi-Angle Central Column (MACC) System allows users to move the central column from 0 to 180-degree angles in variable vertical and horizontal positions, making macro-photography and special-angle shots a breeze. The Instant Swivel Stop-n-Lock (ISSL) System quickly and securely repositions the central column in one simple movement while maintaining the tripod"s stability.
