The Smith-Victor GH-100 Pistol Grip Tripod Panhead is a double-action pistol grip made of high impact polycarbonate--the ball head and platform assemblies are made from aircraft aluminum. By squeezing the handle, you can tilt the camera to any angle up to 90° in any direction. Release the handle and the camera locks instantly. Release the side lock and the camera platform can pan 360° left or right. The side lock can be tightened to increase tension for fluid panning. The 2" x 1.5" quick release plate has a non-slip rubber insert along with a spring pin and screw locks for increased camera safety. A bubble level is built-in.
