Gitzo developed a special technical polymer compound, Soulid 238 (R), in order to achieve such a compact size and low weight. The G2180 head incorporates an adjustable counter-balance system with a choice of seven positions that allow the head to be levelled quickly and makes for easy spotting and tracking of birds in flight. The removable pan bar gives the head a more compact look and allows the head to be used with long photographic lenses.
