National Geographic NGEH1 Expedition Hydrostatic Head RC2

The NGEH1 head is simply the most advanced ball head in the world, incorporating the innovative hydrostatic locking system to produce an absolute rock-solid lock with the small turn of a knob. Using hydraulics instead of a mechanical approach produces a super-tight lock with minimal amounts of knob turning. The effect produced is a smooth moving ball, but when locked, essentially becomes a solid part with the head. This revolutionary head uses the latest materials for silky smooth operation and its magnesium shell produces feather light weight. Ideal for photographers using large telephoto lenses, the NGEH1 is easy to operate, with a newly designed large ergonomic handle with precise friction adjustment. A rubber bellows system prevents dirt and debris from entering the ball area ensuring problem-free photography even in the most extreme locations.
