The GT1542T tripod combines the compactness and light weight of the Gitzo Traveler System with the stability and size of a regular Mountaineer Series 1 tripod. It is perfect for anyone seeking a highly portable support with no compromise. Features:Ground Level Set - allows you to remove the center column to save weight and get the camera closer to the ground. No tools needed. G-Lock Leg Locking System - redesigned locking mechanism achieves a 20% increase in rigidity, faster operation and stronger, safer locking. G-Lock's special design also provides a ''gravity lock'' effect: the higher the load applied vertically to the leg, the stronger the lock. Rapid Column - center column locking collar above the tripod shoulder makes it easier to adjust the column quickly. Series 1 and above are built with an anti-rotation grooved center column for improved stability. Column Hook - built-in accessory hook allows you to hang a stabilizing weight (e.g. a full camera bag or a sand/shot bag) from the bottom of the tripod center column. Useful with long, heavy lenses, on uneven ground or in windy conditions.Anti Leg Rotation (ALR) System - tripod can be opened in less than 15 seconds. Simply loosen all the twist locks on each leg at the same time, then pull the leg down and tighten the locks individually.
