The Gitzo Series 2 Traveler Ball Head with QR Plate are designed more compactly to fit between the feet of the Traveler Series 2 tripod when it is collapsed. The head can support up to 15.4 lb, while weighing only 1.3 lb, thanks in part to its hollow Bubble Ball technology, which achieves a significant reduction in weight. The Series 2 Traveler ball head features an updated quick-release system that accepts both Gitzo C-profile plates, and Arca compatible plates. This QR system allows the plate to be snapped into the head from above, which is faster than sliding it in. With smooth operation, strong-locking materials, and a compact, lightweight design to provide a low-profile ball head that's small and light enough to earn it a spot in any travel bag. Like the bushings, the ball is treated with PTFE, a smooth material that coats the metal ball to enable accurate, low-friction adjustments to your camera's positioning. Bubble levels on the ball head help ensure your camera will be aligned with the horizon.
