The Pole Cam from Beneath the Surface is a 42.0" long underwater camera arm made specifically for GoPro cameras that allows you to shoot photos or videos while snorkeling or scuba diving. The pole is made up of three parts that are connected by an elastic cord so that it can be broken down like a tent pole. When collapsed, the pole measures only 16" long, and when assembled it is 42" long. A 1/4"-20 threaded hole is located on the end of the pole for attaching a camera mount. A rubber grip helps you keep hold of the arm while underwater.
