The Gitzo Gimbal Fluid Head is an ideal place to mount your spotting scope for birdwatching and wildlife photography. With a safety payload weight of 17.64 lbs, you'll struggle to find a scope or large camera lens that this head can't support! It incorporates fluid cartridge technology to absorb external vibrations and provide smoother movement over the full 360° rotational field. The Whip-Pan system ensures this smoothness is maintained for both fast rotations, slow rotations and everything in between. The horizontal and vertical balancing systems make this head a breeze to use with any large lens or scope regardless of how weirdly shaped or unbalanced they may be; the Gimbal Fluid Head compensates for it perfectly. Soft-touch knobs, a detachable pan bar, and lightweight magnesium construction maximize ergonomics so you can focus less on handling and more on shooting! The head features a built-in Arca Swiss long plate with a standard 1/4" screw.
