Our extension cords were made to accomodate those who need a longer than normal distance from their camera.
Our extension cords have a "male" end connector and a "female" end connector.
Simply plug the male end of your controllers built-in cord into the female end of the extension cord.
The male end of the extension cord then plugs into the female receptical on your lens, camera or pan and tilt head.
