The Gitzo Mountaineer Series 1 3-Section Carbon Fiber Tripods dampen vibrations better than previous models thanks to the use of larger diameter lower leg sections. The center column on the tripod can be removed for Ground Level Set, which enables the tripod to reach its lowest height of 6.7". Its three-section legs are secured with twist locks that incorporate an internal O-ring to prevent dust and particles from entering the leg system which prevents long term damage. New large leg angle selectors give you more area to grip when readjusting leg angles. Additionally ballast hook on the center column allows you to add weight to increase the tripod's stability.
