The U.N Underwater Selfie StickⅡ is useful for underwater shooting with a GoPro or Action Cam in shallow water. It can also be used as a grip for a small light. The U.N. Underwater Selfie StickⅡ is made with machined stainless steel screws for better rust resistance and water resistance than conventional products. The Ultra-Lock mechanism allows you to set up a quick extension/contraction and fixation by simply turning the pipe about half a turn.
