Gitzo GT-531 Replaces: GT-530Ever since then they’ve set the standard for performance and quality. The main feature of the range is the new 6X carbon fiber tube, made of a unique structure of 6 crossed layers that maximizes rigidity, vibration absorption and lightweight performance. 6X tube has a high density structure made of top quality ultra-thin carbon fibers. Built-in Anti Leg Rotation is now a feature of the whole carbon fiber range. Mountaineer tripods have been further improved with features and details that increase performance, versatility and quality.Recommended for compact cameras, lightweight camcorders and DSLRs with 75mm lens or 135mm maximum. Given its small size and extremely light weight, this tripod offers a interesting compact solution for the latest generation of small scale digital equipment. The G-Lock system and improved tube structure give good performance in terms of torsional rigidity.All Mountaineer tripods come with a convenient anti dust bag for storage and packing. The textile anti dust bag is also an answer to environmental protection, aiming to reduce the amount of plastic bags that world industry is introducing into the market yearly.Features:ALR - Gitzo has introduced a Anti Leg Rotation System that allows for ultra fast and smooth operation. Thanks to this new system, it is possible to operate all the locks at the same time and then the sections in a single move. With the new ALR it is possible to open a 5-section Traveler tripod in less than 15 seconds.Hook- This built-in accessory allows you to hang a stabilizing weight (e.g. a full camera bag or a sand/water bag) from the bottom of the tripod center column. Useful with long heavy lenses, on uneven ground or in windy conditions. The hook can hold up to 18kg (39.7lb).Ground level set - This feature allows you to remove the center column to save weight and get the camera closer to the ground. Uses existing components: the upper disc with reversible 1/4” - 3/8” bolt and the column hook assembly: remove column and fix the disk directly to the upper casting using the column hook. No tools needed.G-Lock - G-Lock is the Gitzo leg locking system. The locking mechanism has been completely redesigned in order to achieve 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 - The 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.Reversible column hook - The rapid column can easily be inverted for an alternative shooting angle or low level macro work.Leg ends - All tripods and monopods in Series 1 and above are provided with removable rubber feet. This feature allows you to easily change worn out rubber feet or to fit other accessories, such as spiked feet or snow/sand shoes. (4 section tripods in Series 1 are excluded because the final leg section is too narrow to fit these ends).Power disc - The tripod upper disc is called “Power Disc”. It is made of machined solid aluminum and it now features two locking screws, one to lock the head, the other to safely lock the disc onto the column. The “Power Disc” gives a rock solid connection of the whole system for additional safety and stability.
