Off shore, you are correct. Its a woods power grip with female 1/4 thread attached to 1/4" ram "c" (1.5")ball. Connected to radpole 29" which is connect to camera via a ram "b" (1") ball with garmin virb mount. Gpccity.com has a bunch of ram mounts. Always loctite the threads. I always mount cameras to the board when I get to the water. The c ball can snap if bumped by a branch etc...have fun!
