The Promaster PH25 Panoramic Head allows for specific rotational pan movements on a tripod. The upper pan control moves a full 360 degrees smoothly and the bottom has pre-determined stops that are adjustable with the knob inserted into the side. The PH25 can be mounted to most tripods and heads using its common 3/8" threads. A camera is mounted to the PH25 using the included dovetail quick release plate, which is also compatible with a variety of arca-swiss type accessories.
