When you don't have a tripod, you'll want to have the Vanguard PH-210 Window Mount around to be sure you don't miss the shot. The PH-210 includes a quick release plate (QS-36) and a 3-way pan head so that it can be easily attached to car and truck windows, fences, tree branches, tubular objects or even tripods, providing smooth panning and tilting with a camera, camcorder or spotter scope. The maximum width of the material the clamp will fit onto is approximately 0.87" (22 mm).
