A double quick release safety system prevents camera equipment from suddenly dropping out of the head when the quick release locking knob is released. Extremely useful with heavy equipment, long lenses and spotting scopes.
The levelling bubble helps you to get your photographs, film or scope viewing perfectly horizontal or vertical.
Safe Grip is a material that gives a safer lock between your camera and the head plate, preventing the camera from moving or slipping. It is used on quick release plates and in applications where the camera equipment is screwed to the support to reduce pivoting and twisting.
