Quickly mount or swap your 75mm flat base head on a tripod or support with a 75mm bowl using the iFootage 75mm Bowl Head Quick Release Mount BQ-75 the half ball adapter is compatible with most 75mm bowls, including third-party bowls, and it has a 3/8 Inch-16 threaded stud that allows you to mount it on the bottom of flat base tripod heads. A threaded shaft that the tie-down attaches to holds your head in place. The tie-down has a clever release button that allows it to slide up the adapter's threaded shaft. This lets you save time tightening your head on the tripod legs or other support, as you don't have to spin the tie-down all the way up the shaft. Level your head on the tripod, slide the tie-down up, release the button, and turn the tie-down to tighten it in place. To remove, turn the tie-down on revolution and press the release button to slide it off. Remember to hold the video head so it doesn't shift when released.
