The SquidRig 3.0 adds 3 extendable poseable arms for LED lights and shotgun microphone to any standard tripod with a 3/8 -16 screw head mount. An excellent alternative to carrying multiple light and mic stands. Great for video interviews and still photography head shots. Less to carry and setup in minutes! The three rotating brackets allow you to set the position of the light and mic arms both horizontally and vertically and lock into place. Uses ball bearings for smooth rotation.
