The Systematic head is a low-profile, wide, stable quick release ball-type head that fits into the shoulder of a Systematic tripod. It allows a camera to be mounted very close to the top of the tripod for optimal support, and lets the camera be levelled or angled accurately with 28° of tilt. The Systematic head features a hydraulic locking system, which allows faster control, great locking speed and exceptional smoothness. The Systematic Head can be attached to any tripod using the 3/8” thread, or can be fitted into the upper casting of any Systematic Tripod to guarantee an ultra-stable platform. The ring adaptor (GS5300S) is included and is required when using this head with a Series 5 Systematic Tripod. This head also has the new Systematic safety catch: when used together with the latest Systematic tripods equipped with the safety button, the head is held safely in place until the release button is pushed, so that it – and any camera equipment attached to it – is secure even if the tripod top casting is inadvertently left open. The GH5381SQD features the D profile Arca-style quick release plate, which allows the camera and plate to be snapped into the head from above, much quicker than trying to slide it in from the side.
